The results showed matic hammers in the drill bits, effec- that large well yields are available only where aquifers have localized increases in permeability. This occurs mainly in tively preventing deeper drilling. Twenty-five wells in the report area are known to derive water from bottom-hole 1 fractures, all of which are believed to be horizontal stress relief fractures. Other wells in the area are reported to derive water from bottom-hole fractures, which also are believed to be stress relief fractures. These wells occupy a variety of topographic settings, including broad valleys, ridge crests, steep slopes, and bare-rock areas, indicating that stress relief fractures are present beneath uplands and lowlands alike. Wells deriving water from stress relief fractures have much greater average depths than wells reported from other crystalline rock areas. Many of the wells are 400 to 550 feet or more deep and derive water from a single fracture at the bottom of the hole. In one area, 62 percent of the wells that supply 50 gallons per minute or more are from 400 to more than 600 feet deep. The chance of obtaining large well yields from stress relief fractures is significantly increased by drilling to about 620 feet. In general, moderate quantities of ground water presently are available in the report area. Most of the 1,165 highyielding wells that were inventoried during this study supply from 40 to more than 200 gallons per minute. The distri~ution of these wells with respect to topography and geology indicates that most were located for the convenience of the users and that the large yields resulted mainly from chance, rather than from thoughtful site selection. By employing the site selection methods outlined in this report, it should be possible to develop large supplemental ground-water supplies in most of the area from comparatively few wells. Coweta, Fayette, Henry, and Clayton Counties in the south part of the area that include the communities of Newnan, Shenandoah, Peachtree City, and Fayetteville are expected to grow rapidly during the next 25 years. Because of unfavorable quality conditions in the Chattahoochee River, these communities and surrounding areas are being forced to turn to small, marginal streams as watersupply sources. These streams are vulnerable to pollution from nonpoint sources and are seriously affected by prolonged drought. For these reasons, the southern Atlanta area is one that can benefit greatly from supplemental groundwater supplies. At present, all of Coweta County outside the city of Newnan. uses ground water exclusively, and much of the four-county area soon may require ground water for supplemental or primary sources of supply. Large quantities of ground water are available in the four counties, as indicated by the presence of 168 wells that supply 40 to more than 200 gallons per minute. Contrary to popular belief, many wells in the Greater Atlanta Region are highly dependable and have records of sustaining large yields for many years. Sixty-six mainly industrial and municipal wells have been in use for periods of 12 to more than 30 years without experiencing declining yields. Well water in the area generally is of good chemical quality and is suitable for drinking and most other uses. Concentrations of dissolved constituents are fairly consistent throughout the area, and except for iron, rarely exceed drinking water standards. INTRODUCTION Municipal and industrial water supplies in the Greater Atlanta Region (GAR) are derived almost exclusively from surface water taken from rivers, streams, and impoundments. Large withdrawals now and predictions for future needs are causing concern about the present metropolitan area systems being able to meet the anticipated demand. Public pressure is mounting against drawing down recreation and power generation reservoirs to obtain additional water. Thus, there is a great need to assess the availability of ground water in the crystalline rocks of the GAR as a possible alternative 2 source of supply for communities and potential industry outside the existing surface systems. Because of generally low permeability, crystalline rocks have the reputation for furnishing only small quantities of ground water, generally 2 to 30 gal/min, suitable mainly for domestic and farm purposes. As a result, many engineering firms and consultants no longer consider ground water a practical source of supply. This has severely limited the economic development of vast areas not served by municipal or county water systems. There are, however, a significant number of wells in the GAR that produce 100 to almost 500 gal/min. The fact that most of these wells were located without regard to topography or geology indicates that other high-yielding wells could be developed at numerous selected sites in the GAR. A study was needed that would provide methods for locating wells in the GAR that could be expected to supply large quantities of ground water for supplementing the existing surface-water sources. This project was part of a long-range plan to appraise the ground-water resources of Georgia, with particular emphasis on high-growth areas. The data collected and used will be entered into the U.S. Geological Survey computerstored data bank and, along with the published report, will be available to answer information requests and help municipal, industrial, and other planning agencies. Area of Study The GAR as used in this report includes an area of about 6,000 mi2 in west-central Georgia (fig. 1). The study initially was limited to the area covered by the U.S. Geological Survey "Greater Atlanta Region" (1974), 1:100,000-scale topographic map, but later was expanded to include counties along the southern border of the map. As the study is concerned only with metamorphic and igneous rocks of the Piedmont physiographic province, it excludes the northwestern part of the mapped area, which is in the Valley and Ridge physiographic province. All or parts of 27 counties comprise the study area: Barrow, Bartow, Butts, Carroll, Cherokee, Clayton, Cobb, Coweta, Dawson, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Haralson, Heard, Henry, Jasper, Newton, Paulding, Pickens, Polk, Rockdale, Spalding, and Walton Counties. The 1980 population of the GAR was about 2,000,000. Objectives and Scope The objectives of the study were to assess the quantity and chemical quality of ground water available in the GAR, and to develop methods for locating highyielding well sites in various geologic and topographic settings throughout the area. In the GAR, more than 1,165 highyielding wells (yielding a minimum of 20 gal/min) were inventoried and accurately located on topographic maps by field checking. All of the well sites were analyzed to evaluate the correlation between well yield and topographic setting. Detailed field studies were conducted on 1,051 well sites to learn the types of geologic and topographic settings that supply large well yields. These studies assessed (1) the local geology and structure of each site to identify the wells that derive water from fault zones, contact zones, and similar features; (2) the rel'ation between topographic setting and geology, to detect sites where the large yields result from a relation of topography to small-scale structures in the rocks; and (3) the relation of the highyielding wells to the depth and yield of nearby wells to define and delineate the water-bearing openings that supply the large yields. These determinations were used to develop methods for selecting 3 80 MILES Figure 1. Location of study area. 4 high-yielding well sites in a variety of geologic and topographic settings throughout the GAR. The nature and occurrence of waterbearing openings in various rock types were studied by using borehole geophysical techniques. Sonic televiewer logs of well bores were the best -available means of learning the character of deep-seated fractures that supply large well yields in places of seemingly low yield potential. Three test wells were drilled to investigate the yield potential of different geologic settings and to learn the nature of water-bearing openings. Pumping tests were run on two of the test wells to provide drawdown and recovery data needed to estimate yields. Core drilling was done beside two wells to confirm the horizontal nature of waterbearing fractures observed by borehole geophysical logs. A fourth test well was drilled to learn whether a linear feature was underlain by a zone of fracture concentration. High-yielding well sites and waterbearing units were studied in detail in Coweta, Fayette, Clayton, and Henry Counties in an attempt to discover methods for locating sites capable of supplying large quantities of well water. Large quantities of well water soon may be needed in these counties for supplemental supply. Physiography and Climate Most of the report area is a broad rolling upland or plateau that, as a whole, is topographically homogeneous. Almost all of the cities and larger towns are on uplands, away from the rivers and broad valleys (LaForge and others, 1925). The plateau is inclined to the southeast, having average altitudes of 1,000 to 1,200 ft in the northwest and about 700 ft in the southeast. The maximum altitude is 2,300 ft on Pinelog Mountain in Cherokee County; the minimum altitude is 527 ft at Jackson Lake in Newton County. The average altitude of the report area is about 1,000 ft. The northwestern part of the area is drained by the Chattahoochee and Coosa Rivers. The southeastern part is drained by the Flint and Ocmulgee Rivers. Major cities in the area include Atlanta, Gainesville, Marietta, Decatur, Newnan, Carrollton, Conyers, Covington, Canton, Cumming, and Lawrenceville. The area has a mild climate with slightly cooler temperatues and a little less rainfall than the State averages. In Fulton County, the average January temperature is 44F and the average July temperature is 78F. Average annual rainfall is 47 to 48 inches, compared to a State average of 54 inches. There are two peak-rainfall periods: late winter and midsummer. Previous Investigations One of the earliest reports on ground water in the GAR appeared in McCallie's "Underground Waters of Georgia" (1908). A report by Herrick and LeGrand (1949) discussed the geology and ground-water resources of the Atlanta area. Their report covered 2, 055 mi 2 of the "Atlanta area" and included data on dug, bored, and drilled wells. A 1951 report by Carter and Herrick on water resources of the Atlanta rietropolitan Area summarized ground-water data from the Herrick and LeGrand (1949) report, and also discussed availability and quality of surface water in the area. Thomson and others (1956) reported on "The Availability and Use of Water in Georgia," in which the occurrence of ground water in the Piedmont was briefly discussed. Stewart and Herrick (1963) reported on emergency water supplies for the Atlanta area. McCollum (1966) investigated the ground-water resources and geology of Rockdale County, one of the 27 counties included in the present study. 5 Cressler (1970) rep,)rted on the geology and ground-water resources of Floyd and Polk Counties. Cressler and others (1979) presented results of a study on geohydrology in Cherokee, Forsyth, and eastern Bartow Counties. LaForge and others (1925) discussed the drainage systems of the Georgia Piedmont. Staheli (1976) reported on drainage styles of the area's streams that have a bearing on the distribution of ground water in the GAR.

Well-Numbering System The GAR is covered by 111 7.5-minute topographic quadrangles and parts of quadrangles. Wells in this report are numbered according to a system based on the 7.5-minute topographic quadrangle maps of the U.S. Geological Survey. Each 7.5-minute quadrangle in Georgia has been given a number and a letter designation according to its location. The numbers begin in the southwest corner of the State and increase numerically eastward. The letters begin in the same place, but progress alphabetically to the north, following the rule of "read right up." Because the alphabet contains fewer letters than there are quadrangles, those in the northern part of the State have double letter designations, as in 9HH. (Refer to fig. 37.) Wells in each quadrangle are numbered consecutively, beginning with number 1, as in 8CC1. Complete well numbers, as in 5CC11, are used in well tables and most illustrations. On plate 1 the well numbers lack quadrangle designations because of space limitations. The quadrangle designations for these wells can be obtained from figure 37 and from the inset on plate 1. 6 In table 7, which lists chemical analyses of well water, some wells retain numbers used in previous reports. WATER-BEARING UNITS ANU THEIR HYDROLOGIC PROPERTIES The part of the GAR included in this study lies wholly within the Piedmont physiographic province (Clark and Zisa, 1976; Fenneman, 1938). The area is underlain by a complex of metamorphic and igneous rocks that have been divided by various workers into more than 50 named formations and unnamed mappable units. Individual rock units range in thickness from less than 10 ft to possibly more than 10,000 ft. Regional stresses have warped the rocks into complex folds and refolded folds, and the sequence has been injected by igneous plutons and dikes and broken by faults. Erosion of these folded and faulted rocks produced the complex outcrop patterns that exist today. The large number of rock types in the area and their varied outcrop patterns greatly complicate the occurrence and availability of ground water in the area. Nevertheless, many of the more than 50 named formations and unnamed mappable units in the GAR are made up of rocks that have similar physical properties and yield water of comparable quantity and chemical quality. Thus, for convenience, the rocks in the report area have been grouped into nine principal water-bearing units and assigned letter designations.

This recharge is from precipitation that falls in the area. Unweathered and unfractured bedrock in the report area has very low porosity and permeability. Thus, the quantity of water that a rock unit can store is determined by the capacity and distribution of joints, fractures, and other types of secondary openings. The quantity of stored water that can be withdrawn by wells depends largely on the extent to which the rock openings are interconnected. The size, spacing, and interconnection of openings differ greatly from one type of rock to another and with depth below land surface. Open joints and fractures tend to become tighter and more widely spaced with increasing depth. Joints and other openings in soft rocks such as phyllite tend to be tight and poorly connected; wells in rocks of this character generally have small yields. On the other hand, openings in more brittle rocks such as quartzite and graywacke tend to be larger and are better connected; wells in these rocks normally supply greater yields. Other rocks, including amphibolite, schist, and gneiss, are variable in the size and connection of secondary openings and generally yield small to moderate quantities of water to wells. Carbonate rocks, which include marble, can contain much larger and more extensively interconnected fracture systems. Openings in carbonate rocks commonly are enlarged by solution, and are capable of transmitting large quantities of water. Effects of Drainage Style The GAR is divided nearly in half by the Chattahoochee River, which follows a comparatively straight southwesterly course for nearly 110 miles across the area (fig. 1). Streams in the north half of the area, including the Chattahoochee River and its tributaries, mainly have rectangular and trellis drainage styles. In contrast, streams in the south half of the area, beginning at about the south edge of the Chattahoochee River basin, have a dendritic drainage style (Staheli 1976). , Streams having rectangular drainage style flow in strongly angular courses that follow the rectangular pattern of the joints that break up the rocks. Areas having trellis drainage style are characterized by strongly folded and dipping rocks; the larger streams follow the outcrops of less resistant rocks and tributaries enter at right angles across the dip of the strata (Lobeck, 1939, P 175). All of the streams in the north half of the area show the influence of geologic control, their drainage styles reflecting the varied outcrop pattern, the different lithologies present, and the geologic structure. In the south half of the area, the dendritic drainage style is indicative of streams that developed independently of the underlying geology (LaForge and others, 1925; Staheli, 1976). According to Staheli (1976, p. 451), dendritic drainage, in which streams run in all directions like the branches of a tree, probably was established on some preexisting surface and later superimposed on the underlying crystalline rocks. Such streams are said to be superimposed when they acquire a course on nearly flat-lying material that covered the rocks beneath. Streams flowing on the veneer of material that covers the bedrock are superimposed above the concealed rocks. When rejuvenated by uplift, they become incised and develop courses without.regard to the structure or lithology of the underlying rocks. Eventually, the cover material may be entirely removed and then only the physiographic pattern of the streams will suggest their having been let down from a superimposed position (Lobeck, 1939, P 173). According to Staheli (1976, p. 451), to explain the different drainage styles in regions underlain by similar rocks and 9 structures, it is suggested that an earlier Coastal Plain sedimentary cover buried the Piedmont and extended inland at least to the Chattahoochee River valley. Thus, according to Staheli, drainage to the north developed originally on Piedmont rocks and so reflects their structural orientations. Staheli believes that streams south-of the Chattahoochee River valley developed as consequent streams on a flat Coastal Plain cover. These streams extended headward as sea levels lowered, developed dendritic drainage, and eventually became superimposed across regional Piedmont structures. Thus, the general area of the Chattahoochee River valley might well coincide with a fossil Fall Line in Georgia (Staheli, 1976, P 451). As Staheli points out, in areas near the Chattahoochee River, the drainage pattern suggests that higher, more resistant rocks could have existed as islands that locally controlled stream development even though the lower areas were covered by Coastal Plain sediment. For example, drainage obviously has been diverted by such prominences as Stone Mountain. Observations made during the present study indicate that in the south half of the GAR, many of the smaller elements of the drainages, such as draws, hollows, and intermittent streams in the uppermost headwaters areas seem to have developed under geologic control. The presence of geologic control is indicated by smaller drainages that parallel prominent joint sets or that are alined with bedrock foliation. Presumably these late-forming drainages were established after removal of a preexisting cover and, therefore, developed under geologic control. The fact that the smaller drainages may reflect bedrock weaknesses, whereas the larger streams generally may not, has a profound influence on the occurrence of ground water in the south half of the GAR and on the methods that can be used successfully to locate large ground-water supplies. The relations between drainage styles and the occurrence of ground water, and the effects that drainage styles have on the methods that can be used to locate sites for high-yielding wells, are discussed in later sections of this report. AVAILABILITY OF LARGE GROUND-WATER SUPPLIES The quantity of ground water available in the GAR varies greatly with the location, rock type, topographic setting, drainage style, and the geologic structure. In some areas, most wells yield less than 3 gal/min, which generally is considered a minimum requirement for domestic and stock supplies. In more favorable areas, yields commonly range between 3 and 10 gal/min. It should be pointed out, however, that obtaining this quantity may require drilling in more than one site. High-yielding wells--ones that supply 20 gal/min or more--generally can be developed only where the rocks possess localized increases in permeability. This occurs mainly in association with certain structural and stratigraphic features, includiqg: (1) contact zones between rock units of contrasting character, (2) contact zones within multilayered rock units, (3) fault zones, (4) stress relief fractures, (5) zones of fracture concentration, (6) small-scale structures, including joints, foliation planes, and fold axes, that localize drainage development, (7) folds that produce concentrated jointing, and (8) shear zones. Other factors, such as topographic setting, drainage style, rock type, depth of weathering, thickness of soil cover, and the pervasiveness and orientation of foliation can interact to increase or decrease the availability of ground water. The nature and occurrence of structural and stratigraphic features known to increase bedrock permeability, and the relation of these features to drainage style, topography, and other factors, are discussed in the following sections. 10 Contact Zones Yields of 50 to 200 gal/min may be obtained from contact zones between rock units of contrasting character. The largest yields generally are obtained where massive homogeneous rocks such as granite, which are very resistant to weathering, are in contact with foliated rocks of high feldspar content that weather rapidly and deeply. The most productive contacts generally are ones in which a resistant rock is overlain by a rapidly weathering rock (T. J. Crawford, West Georgia College, oral commun., 1979). Examples of rock types and certain physical characteristics of rocks that form productive contact zones are shown below: 1. Granite or granitic gneiss overlain by schist low in quartz content. 2. Granite overlain by hornblende, feldspar (50 percent) gneiss. 3. Granite overlain by feldspar gneiss. 4. Hassive granite overlain by foliated gneiss. 5. Hassive, homogeneous rocks, poorly jointed and foliated and resistant to weathering, overlain by foliated, well-jointed, deeply weathering rocks (feldspar-rich and foliated rocks weather most rapidly and deeply). To produce the highest yields, the rocks overlying the massive homogeneous rock should be: (1) foliated, (2) have a high feldspar content, the higher the be~ter, (3) differ mineralogically, and (4) occupy a topographic position favorable to recharge. Contact zones occur throughout the GAR. Many potentially high-yielding contacts are shown on plate 1, and on detailed geologic maps that are available for parts of the area. (See references.) Contact zones between rock units of contrasting character generally may be recognized in road cuts, quarries, and freshly scraped areas, and their presence also may be indicated by changes in the character of the saprolite and by changes in topography. For example, the contact between granite or granitic gneiss and a feldspathic schist may be indicated by sandy soil or saprolite containing small mica flakes derived from the granite or gneiss, that abruptly changes to a clay soil containing large mica flakes derived from the schist. Also, the area underlain by granite or gneiss may be characterized by numerous exposures of fresh rock, whereas the schist area may have no rock exposed. Contact zones between resistant and less resistant rocks also may be indicated by subtle changes in topography. The terrain over the weaker rocks may be slightly lower and flatter than that over the resistant rocks. Valleys and draws may trend parallel to the contact zone. In the north half of the GAR, wells derive large yields from several types of contact zones. Well 12H:-I6 furnishes 150 gal/min to the city of Cumming, Forsyth County, from quartzite of Unit H at the contact with schist of Unit c. Well 5CC- 39 in Carroll County supplies a subdivision with 100 gal/min from a contact zone between "granite" of Unit F and schist of Unit C. In the south half of the area, comparatively few wells supply water from contact zones between rock units of contrasting character. This probably is because in an area dominated by dendritic drainage, the contacts rarely occupy topographic settings that favor increased ground-water circulation. Large yields are, however, supplied by wells that tap contact zones between mafic rocks of Unit E and various types of country rock. Well 14DD2, near Milstead in Rock~ale County, supplies 100 gal/min from a contact between a diabase dike (Unit E) and granitic gneiss of Unit B. Contact zones between differing rock units are widespread in the south half of the area and 11 may be productive where they underlie draws, stream valleys, and other low areas that fa-vor increased ground-water circulation and provide adequate recharge. Other potentially permeable contact zones occur between rock layers of different character within multilayered rock units such as Unit A. Areas underlain by Unit A are shown on plate 1. Although individual contact zones cannot be shown on maps of the scale used in this report, they may be located by field surveys. Contact zones of this type supply water to wells in both the north and south halves of the area. Well 12HH7 in. Forsyth County derives 90 gal/min from contact zones within the multilayered rock of Unit A. The yield potential of individual contact zones may be estimated from their topographic settings, especially their relation to local drainages. The largest yields generally can be expected from contacts that lie in and trend parallel to draws and stream valleys that are downgradient from sizable catchment areas overlain by deep soil. Contacts that cross such drainages at various angles also may be productive. Contact zones in multilayered rock units generally supply the largest yields to wells drilled on the downdip side of draws and stream valleys that parallel the contacts. Construction of the "people mover" tunnel at Hartsfield-Atlanta International Airport provided an opportunity to observe firsthand the effects that topographic setting, catchment area size, and quantity of available recharge have on the long-term yield potential of contact zones in multilayered rocks. The tunnel site, which extended in an east-west direction for nearly a mile (fig. 2) over interlayered schist, gneiss, and amphibolite of Unit A and gneiss of Unit B, was being dewatered along the north and south sides by wells drilled at intervals of about 100 ft. The dewatering wells were 110 ft deep, gravel packed to the top of rock, and lined with slotted casing to total depth. Observation wells 60 ft or more deep and gravel packed to total depth were spaced every 200 ft along both sides of the tunnel site to permit the monitoring of water levels. The initial yields of the dewatering wells reportedly ranged from near 0 to about 70 gal/min, averaging about 10 gal/min. Submersible pumps installed in each well discharged water at the rate of about 17 gal/min, cycling on and off as needed to prevent excessive drawdown. As the dewatering operation progressed, many pumps were off most of the time; only the highest yielding wells pumped steadily. Because new groups of wells were intermittently completed and brought on line, and older wells were pumping less often, the most practical means of determining the total pumpage of the dewatering wells was to measure the flow in discharge ditches that collected water from wells on the north and south sides of the tunnel site. The first measurement, made February 2, 1977, showed the total pumpage to be about 100 gal/min (not accounting for evapotranspiration or seepage). With the addition of more pumping wells, the discharge increased to about 1,000 gal/min on August 1. By October 10, many wells had stopped pumping and the total discharge declined to about 500 gal/min. On January 11, 1978, the flow was reduced to about 100 gal/min and by Harch 31 the flow, which was too small to measure with a pigmy current meter, was estimated to be less than 50 gal/min. The flow in the discharge ditches remained too low to measure for the remainder of the dewatering operation. By June 28, 1978, most wells had stopped pumping and the highest yielding wells were cycling irregularly. The dewatering operation proved successful for the intended purpose of lowering the water table below the bottom of the construction ditch. Ground-water levels at the beginning of the operation ranged from about 4 to 12 ft below land surface. With the start of pumping, the 12 0E~-3.--.E-3~--,E-~3~-------------.' MILE CONTOUR INTERVAL 20 FEET NATIONAL GEODETIC VERTICAL DATUM OF 1929 Figure 2. Well sites in the "people mover" tunnel area, Hartsfield-Atlanta International Airport. Sites A and B are downgradient from catchment areas supplying recharge; sites C and D are in interstream areas receiving little recharge. 13 water level in some ob1:ervation wells declined more than a foot per day. Other wells responded slowly and showed little change in water level after 4 days of pumping. With continued pumping, however, the water levels in all observation wells declined, and by May 25, 1978, were drawn down to depths of 16 to 38 ft below land surface. By August 1978 the water level was generally in the range of 27 to 39 ft below land surface, well below the bottom of the construction ditch. The low water level kept the ditch free of seepage except immediately following heavy rains. This decline in water levels and the reduced yield of the few active wells, clearly indicated that ground-water storage in the saprolite largely had been depleted. The monitoring of water levels also revealed that saprolite of layered rocks at the site (amphibolite, gneiss, and schist) has strong preferential permeability. Observation wells that had shown little response to nearby pumping wells located across the strike of the rocks immediately began drawing down with the start-up of wells along the strike. Preferential permeability in the saprolite of layered rocks (documented by Stewart, 1964) accounts for differing rates of drawdown that occurred during the dewatering operation. The highest yielding well (70 gal/min at site A, fig. 2) penetrated interlayered schist, gneiss, and amphibolite and probably derived water from more than one interformational contact zone. Other wells in the 20-30 gal/min yield range (sites B, C, and D, fig. 2) penetrated interlayered schist, granite gneiss, and some amphibolite. The dewatering operation demonstrated the importance of locating high-yielding wells in topographic settings that can supply recharge in quantities large enough to balance intended withdrawals. After months of pumping, only the wells in stream valleys downgradient from sizable catchment areas (sites A and B, fig. 2) continued to supply significant yields. Wells in interstream areas (sites C and D, fig. 2), on the other hand, where the quantity of recharge is limited, declined in yield and eventually were pumped dry. The response of this well field to pumping was much the same as others in the GAR and adjacent areas of the Georgia Piedmont. Over the long term, wells tapping permeable contact zones or other types of permeable zones, no matter how large the initial yield, can supply water only at the rate it is replaced by recharge. Normally, the recharge needed to sustain high well yields for extended periods, and especially through prolonged droughts, is available only in stream valleys, drainages, and draws that receive constant recharge from large catchment areas, or in broad flat areas covered by deep saturated soil. A leading cause of declining well yields in the report area is the practice of locating wells without regard to the adequacy of available recharge. For this reason, successful methods for locating highyielding well sites emphasize the importance of considering the adequacy of available recharge. Fault Zones Faults in the report area consist of two types: (1) large fault zones, such as the Brevard Zone (Unit G, plate 1), that have extensive rock deformation (cataclasis) and numerous small faults within the zones, and (2) faults that displace rock units without extensive deformation around the fault zone. In large fault zones, shearing and deformation within the zone may reduce the overall permeability of some types of rock and increase the permeability of others. Limited data indicate that wells in broad lowland settings may be highly productive in the Brevard Zone. Owing to the small number of wells and to poor exposures in lowland areas, however, data are not available to indicate which lithologies within the Brevard Zone are the most productive. 14 Faults that displace rock units without extensive deformation may be highly permeable and supply large well yields. The largest yields generally are available from faults that involve both resistant rocks such as massive gneiss or granite (Units B and F) and less resistant rocks such as feldspathic schist (Unit C). Increases in permeability along these faults result from differential weathering of the contrasting rock types, much the same as occurs in permeable contact zones. Although fractures produced by movement on the faults typically have been healed by mineralization and no longer are fully open, the shearing and mixing of rock types contribute to increasing the permeability along the faults. A good example of a permeable fault zone is the one that extends from eastern Carrollton, Carroll County, southwestward more than 5 miles, involving schist (Unit C) and granite (Unit F). Several wells in the fault zone yield 20 to 80 gal/min. Work in crystalline rocks in eastern Georgia by David C. Prowell (U.S. Geological Survey, oral commun., 1980) has shown that relatively recent faults are unmineralized and contain open fractures. The faults consist of one or more zones 10 to 30 ft wide in which the rock is broken by numerous vertical or nearly vertical fractures 1 to 4 inches apart. Between the individual fractures, the rock commonly is brecciated and the pieces are rotated at various angles. A 4- to 6-inch wide zone of fault gouge (rock flour) generally occurs near the middle of each fracture zone. The fractures in the fault zone are open and should be capable of storing and transmitting large volumes of ground water. Although no recent faults were recognized during the present study, they may be present in the GAR. Where they project into topographically low areas favoring increased recharge, recent faults should supply large well yields. According to Prowell (U.S. Geological Survey, oral commun., 1980), except in fresh-rock exposures such as in deep road cuts and quarries, these recent faults are difficult to recognize. Their presence cannot be detected in the soil horizon, but relicts of breccia or variously oriented rock fragments may remain visible in saprolite. It is not known whether the faults would produce a surface trace recognizable as a topographic feature such as a lineament, but it seems likely that they might bring about noticeable changes in vegetative vigor. The likelihood of their producing lineaments probably would be greater in the north half of the area than in the south half. Stress Relief Fractures Water-bearing openings in crystalline rocks traditionally have been described as steeply inclined and "X"-shaped fractures and joints similar to those pictured in figure 3 (LeGrand, 1967, p. 6). These openings are reported to be most numerous and to have the largest waterbearing capacity near the surface and to become tighter and more widely spaced with increasing depth. According to LeGrand (1967, p. 5), most of the interconnecting openings occur less than 150 ft below land surface and few extend deeper than 300 ft. Tradition also has held, as stated by LeGrand (1967, p. 1-2), that high-yielding wells are common where relatively low topographic areas and thick residual soils are combined, and low-yielding wells are common where hilltops and thin soils are combined. Accordingly, sites having the largest yield potential are assumed to be draws and valleys in or downgradient from large catchment areas having a deep soil cover. Sites having the lowest yield potential are narrow ridge tops and upland steep slopes having little, if any, soil cover. From the beginning of this study, it was apparent that many high-yielding wells, particularly in the south half of the GAR, occupy topographic settings indicated by previous workers to have low 15 A 3 percent 8 20 percent c 15 percent 32 percent E 2 5 percent 5 percent Figure 3. Six types of ground conditions showing distribution of fractures that influence the yields of wells. The stippled pattern represents soils and soft rock; the dashed line is the water table. The degree of frequency of the different types is shown in percentage. (LeGrand, 1967). yield potential. These wells are on hilltops, ridge crests, and steep slopes, and many are in areas that have extensive rock outcrops and little or no soil cover. According to the statistical data presented by LeGrand (1967, P 3), such sites should have only a slight chance of supplying large well yields. Moreover, about 14 percent of the high-yielding wells throughout the report area derive water from depths of 400 ft or more (table 9). Thus in the GAR, particularly in the south half of the area, a large percentage of the high-yielding wells derive water from bedrock openings more than 400 ft deep, which is a significant departure from the findings presented by LeGrand for wells in other crystalline rock areas. Because of the inconsistancies between the occurrence of ground water in the GAR, especially in the south half of the area, and those reported from other crystalline rock areas, the authors decided to investigate the nature of waterbearing openings that supply large well yields. The intent was to identify whatever differences might exist between water-bearing openings in the GAR and those in other areas that could explain these inconsistencies. Borehole Geophysical Logs The most practical means available to study the nature of water-bearing openings in wells was borehole geophysical logs. A complete set of geophysical logs was run by the u.s. Geological Survey Southeast Region logger on test well 2 (8CC8) and 3 (9DD1). Logs also were run on high-yielding municipal wells in Turin, Coweta County, and Demorest in Habersham County and Blairsville in Union County northeast of the GAR. The results showed that the nature of bedrock openings could best be studied by using caliper and sonic televiewer logs. Caliper and sonic televiewer logs were run on five additional wells in different types 16 of crystalline rocks and different topographic settings to learn more about the character of water-bearing openings. The caliper log is a graph of wellbore diameter, and it is useful because it indicates fractures and other bedrock openings, and gives a general indication of the vertical dimension of each opening (fig. 4). By matching the caliper log with driller's records of where water entered the well, it generally is possible to identify water-bearing openings. However, the caliper log is unable to reveal details about the nature of the openings. The sonic televiewer log makes possible the visual inspection of the entire well bore, providing detailed information about rock texture, foliation, and bedrock openings. The log is made by a geophysical probe transmitting a rotating sonic beam that reflects off the inside of the well bore and the walls of fractures and other openings. The reflected signal is electronically converted into visual images of the well bore, projected on a video screen, and photographed to provide a permanent record of the image. The photographs show variations in rock texture, layering, and foliation as shades of gray; and open fractures, deep voids, and eroded zones as areas of black (figs. 5 and 6). The images on the photographs are at a known vertical scale and are oriented with respect to north, providing a means for measuring the approximate height of openings, determining whether they are flat lying or inclined, and measuring the strike and dip of inclined features. Televiewer logs revealed that waterbearing openings in high-yielding wells supplying 40 gal/min or more differed from what had been reported for crystalline rocks. The logs showed that in granitic gneiss and biotite gneiss and in quartz-mica schist, water-bearing openings consist of horizontal or nearly horizontal fractures 1 to 8 inches in vertical dimension and range in depth 80 1w - w LL 100 u w ~ 120 n:: ::::> (f) 0 z <( _J 140 ~ w_J CD I I- Cw... 160 0 180 200 4 6 8 DIAMETER OF WELL BORE, IN INCHES Figure 4.

Drill Cores To verify that the televiewer logs were being correctly interpreted and to examine the surfaces of horizontal fractures for possible slickensides or other evidence of horizontal movement, the bedrock was core drilled at two well sites. The core drilling was done by the U.S. Geological Survey using a special triple tube core barrel to insure that all of the core would remain intact so that the extent of fracturing and the weathering of fracture surfaces could be properly evaluated. During the coring process, changes in drilling rate, rotation pressure, and water pressure, which indicated the presence of openings in the rock, were precisely recorded relative to hole depth so that the exact vertical dimension of the void could be calculated. Accordingly, coring runs were exactly 10 ft in length and the amount of void space indicated by measuring the actual rock core was compared with the drilling records about the voids. These measurements of the void spaces were within 10 to 20 percent of each other. One core, from the site of well 13DD90, Rockdale County, penetrated granitic gneiss and confirmed that the horizontal fractures and the enlarged soft zones had been correctly identified and measured (fig. 7). The other core, from the site of test well 2 (8CC8), Fulton County, penetrated interlayered gneiss and schist and confirmed correct identification and measurements of horizontal fractures in that well. The core also revealed weathered foliation-plane openings, mostly at the contacts of schist and gneiss layers, that had not been recognized as openings in the televiewer pictures (fig. 8). No evidence of horizontal displacement was found on any surfaces of the openings. The horizontal nature of the observed water-bearing fractures, the range of depths at which they occur, the types of topographic settings they underlie, and the rock types in which they are present, all suggest that the openings may be stress relief fractures (Wyrick and Borchers, 1981). The mechanism for forming horizontal stress relief fractures seems to be the upward expansion of the rock column in response to erosional unloading (Billings, 1955, p. 93; Wyrick and Borchers, 1981, p. 12), as shown in figure 9. The formation of stress relief fractures seems to be dependent on the volume of overburden removed relative to the area being eroded, as in a broad stream valley (fig. 28), or from the area adjacent to a ridge or upland area, as commonly occurs with divide ridges. Stress relief fractures probably do not lie entirely along a horizontal plane, but are very low dome-shaped structures that in cross section would appear as low arches (fig. 10). The fractures probably are circular or elliptical in plan view, are slightly inclined near the outer edges, and have the maximum void space near the center. Televiewer pictures indicate that stress relief fractures an inch or so high (which could be near the outer edge of the fracture) are inclined about 5 degrees. Th~ arching may produce vertical fractures that extend toward the surface, providing avenues of recharge. They also may serve to connect two or more stress relief fractures, thereby forming a network of interconnected fractures. Horizontal stress relief fractures seem to occur mainly in large bodies of granitic and biotite gneiss (waterbearing Units B and D), but they also are important in units consisting of gneiss interlayered with schist (Unit A) and in schist (Unit C) and amphibolite (Unit E). 19 LLI u <( aL:L: 25 e:::n:> 0z 26 <( ..J ~ 27 0 ..J LLI m 28 1- LLI LLI LL z 29 ~ J: 1ll. 30 LLI 0 - .. -- --:--- -----~ .,.._ .....,.---- ...... - - -.. . ... --. - . . r .... - N Es wN -GRANITIC GNEISS VOID 6 in. ,-:it'lil-- GRANITIC GNEISS ~<-- 1.9 in.--~> Figure 7.

The frac- tures probably are low arches that have the largest opening near the center. Horizontal fractures probably form significant water-bearing openings in large bodies of gneiss in the south half of the area and possibly area-wide. Horizontal fractures were observed in one well (at Demorest, Habersham County, northeast of the GAR) in quartz-mica schist, and they may be a common occurrence in schist units having a high quartz content. Water-bearing stress relief fractures also may occur in granites, although none were identified during this study. Bottom-Hole Fracture Wells Driller's records show 25 wells in the report area that unquestionably derive large yields from openings at or near the bottom of the well. All of the wells share the characteristic of remaining dry, or essentially dry, during drilling until they penetrated one or two highyielding fractures. The high-yielding fractures are at or near the bottom of wells because: (1) the large yields were in excess of the desired quantity and, therefore, drilling ceased, or (2) in deep wells yielding SO to 100 gal/min or more the large volume of water from the fracture(s) "drowned out" the pneumatic hammers in the drill bits, effectively preventing deeper drilling. Four wells having identical characteristics were shown by sonic televiewer logs to derive water from horizontal fractures. Therefore, the writers believe that the bottom-hole fracture wells derive water from horizontal stress relief fractures. Bottom-hole fracture wells are of particular interest because they include the highest-yielding wells in the study area. Construction data, topographic settings, and geology for 25 wells that derive water from bottom-hole fractures are given in table 4. The general locations of the wells are shown in figure 11. In addition to the 25 wells listed in table 4, several other wells in the GAR share the characteristic of remaining nearly dry during drilling until they 23 Table 4.--Construction data, topographic setting, and water-bearing units of bottom-hole fracture wells WaterWell bearing number unit Yield (gal/min) Depth (ft) Casing depth (ft) Depth of water- bearing fracture (ft) Topography 4CC2 c 7BB42 D 8AA10 A 9CC18 A 9HH5 A 10AA9 A 10CC11 B 10CC12 B 10EE5 D 10EE29 G 10HH2 A,C 11CC8 A 12BBS A 12CC14 B 13CCS8 A 13DDS5 B 13DDS6 B 13DD69 B 13DD89 B 14CC14 A 14FF3 B 14FF7 E 14FF8 E 14FF9 E 14FF10 E 100 328 -- 87 330 52 200 352 85 30 405 so 200 526 12 200 175 -- 100 160 18 50 150 30 110 450 27 100 430 so 150 346 92 40 345 56 100 105 55 150 146 126 100+ 340 -- 120 550 34 348 410 103 172 435 25 150 230 12 34 200 10 100 398 46 254 265 54 471 302 30 400 352 40 270 386 20 325 Near head of large draw on slope of divide ridge. 330 Near head of draw on divide ridge. 320 Divide ridge surrounded by stream heads. 110 Point of land. 526 Do. -- Point of land projecting into stream valley and shear zone. 150 Saddle on ridge at head of two draws. 140 Point of land. 443 Head of draw on ridge slope. 430 Point of land projecting into flood plain. 330 Broad point of land; at head of draw on ridge slope. 335 Head of draw on ridge slope. 65 Crest of broad ridge. 140 Head of draw near crest of narrow ridge. 335 Point of land. 540 Crest of divide ridge sur- rounded by steam heads. 400 Head of draw on divide ridge surrounded by stream heads. 430 Crest of divide ridge sur- rounded by stream heads. 220 Do. 173 Do. 395 Ridge crest. 250 Draw on ridge slope. 290 Near head of draw on slope of divide ridge. 340 Base of ridge in stream valley. 330 Stream valley. 24 500,000, 1970 0 10 20 30 40 MILES Figure 11.

According to the memories of their owners and drillers, these wells derived their entire yields from one or two openings at or very near the bottom of the holes. The writers believe these wells also are bottom-hole fracture wells that derive water from stress relief fractures, but they were omitted from the table because no written records of the wells were available. Areal Extent of Stress Relief Fractures No practical means was found to measure the areal extent of stress relief fractures. Conyers well 13DD56, which is 410 ft deep and supplies 348 gal/min, is known to be connected with a 470-foot deep residential well about 400 ft to the north-northeast. The connection between the two wells was discovered when compressed air used to drill the residential well began escaping from the Conyers well. Well 13DD90, about 2 miles southwest of Conyers, which derives water from horizontal fractures, is affected by wells 300 and 600 ft to the south, and seems to interfere with a well about 1,000 ft to the west. Conyers wells 13DD54 and 13DD55, on the other hand, are about 1,500 ft apart and tap separate horizontal fractures. The spacing of these and other wells indicates that horizontal stress relief fractures probably range from as little as 100ft to more than 1,000 ft across. The areal extent of individual fractures may be controlled by rock type, the size of the rock body, the geologic structure, and the amount of overburden removed relative to the area of the fracture. Locating Horizontal Stress Relief Fractures Because of their horizontal nature and the fact that they occur mainly at depths of 150 to more than 600 ft, stress relief fractures are not revealed by structural and stratigraphic features normally associated with increased bedrock permeability. The only clue to their presence, recognized thus far, is topographic setting. Although wells tapping horizontal fractures occupy a variety of topographic settings ranging from ridge crests to broad stream valleys, a large percentage of the wells occur in three rather distinct types of topographic settings. A knowledge of these settings may aid in selecting sites for high-yielding wells in areas having horizontal fractures. The types of topographic settings are: A. Points of land formed by (1) two streams converging at acute angles (fig. 12B, C), (2) two subparallel tributaries entering a large stream (fig. 12A, D), and (3) land protruding into the wide flood plains of large streams (fig. 12E). In 1 and 2, the points of land generally are less than 2,000 ft across. B. Broad, relatively flat ridge areas, commonly on divide ridges, that are surrounded by stream heads (figs. 13 and 14). The wells are on the ridge crests and in the upper reaches of streams flowing off the ridges. Such areas are the sites of many towns and communities and, therefore, are centers of municipal and industrial pumpage. C. Broad valleys formed by the removal of large volumes of material relative to the land on either side (fig. 28). 26 Base from U.S. Geological Survey Brooks 1:24,000, 1965 E Or-Ed-..,----,I==I---.--....,F3--r-----------,l MILE CONTOUR INTERVAL 20 FEET NATIONAL GEODETIC VERTICAL DATUM OF 1929 EXPLANATION IOCCI2 e WELL AND IDENTIFICATION NUMBER 50 Well depth, in feet 30 Casing depth, in feet 50 Yield, in gallons per minute Figure 12.

Wells 1, 2, and 3, each 600 feet deep, are dry. 29 Zones of Fracture Concentration Aquifers of low to moderate productivity may yield large quantities of water to wells from localized zones of increased porosity and permeability created by the concentration of fractures. These zones of fracture concentration generally are between 30 and 200 ft wide, along which the bedrock is shattered to an indefinite depth by numerous, nearly vertical, closely spaced fractures or faults of small displacement that.~ are alined approximately parallel to the long axis of the fracture zone (fig. 15). The zones of fracture concentration extend in straight or slightly curved lines that range in length from a few hundred feet to several miles. Straight or slightly curved linear features a mile or more long, associated with these fracture zones, are visible on aerial photographs and topographic maps and are known as lineaments; shorter features are called linears. Zones of fracture concentration tend to localize valley development. Rock weathering is greatest along these fracture zones because they transmit large quantities of moving water. The increased chemical weathering, coupled with the erosive action of surface water, localizes the valleys over these fracture zones (fig. 16). The chances of obtaining a high-yielding well are good in the floors of valleys developed over a fracture zone (Parizek, 1971, p. 28-56). Valleys developed over fracture zones commonly possess distinctive characteristics that make them recognizable on topographic maps, aerial photographs, and satellite imagery. Among the features most easily recognized are: (1) straight stream and valley segments, (2) abrupt, angular changes in valley alinement, and (3) alinement of gullies, small depressions, or sinkholes (in marble). In the GAR, zones of fracture concentration have localized valley development mainly in the north part of the area where topographic features developed Figure 15. Zones of fracture concentration consist of nearly vertical closely spaced fractures.

Valley development localized along zones of fracture concentration. Modified from Parizek (1971). 31 under geologic control. Several highyielding wells in the north part of the area occupy sites on the floors of straight stream valleys that seem to have developed over fracture zones. For example, the water supply for the Lake Arrowhead resort community, in northwest Cherokee County, was successfully developed in rugged terrain characterized by generally low-yielding wells, by drilling into zones of fracture concentration. Six production wells that penetrate zones of fracture concentration supply a combined total yield of about 560 gal/min. Driller's. logs revealed that all of the wells having yields between 50 and 200 gal/min penetrated sizable fracture systems consisting of one or more large fractures or zones of closely spaced fractures. The largest yields came from zones of closely spaced fractures. All the high-yielding wells occupy sites along straight stream segments, or where valleys make abrupt, angular changes in direction. Figure 17 is a map of part of the Lake Arrowhead area showing the locations of high-yielding and low-yielding wells, to illustrate how yields relate to topographic settings. All of the high-yielding wells are in settings that strongly suggest the presence of zones of fracture concentration. As most zones of fracture concentration are rather narrow--30 to 200 ft wide --precision in locating wells was required to insure penetration of the water-bearing fractures. For example, wells 9JJ6 and 9JJ8 penetrated a fracture zone and yielded 80 and 200 gal/min, whereas well 9JJ12, which is situated slightly off the fracture zone, penetrated mainly solid rock and yielded only 13 gal/min. Valleys possessing the distinctive characteristics of those developed over zones of fracture concentration--straight stream and valley segments; abrupt, angular changes in valley alinement; and alinement of gulleys, small depressions, and gaps in ridges--are common in the north part of the GAR. Many of these features overlie permeable fracture zones and may be capable of supplying large yields to wells. For example, wells llGGll and 11GG12 in Forsyth County each supply 200 gal/min from a fracture zone in amphibolite of water-bearing Unit E. The fracture zone, which runs at nearly right angles to the strike of the rock, underlies two straight stream segments that are alined with a gap in the intervening ridge (fig. 18). Numerous straight stream segments of similar character occur in the north part of the area and may supply large quantities of water to wells. Field investigations showed, however, that not all linear features in the north part of the area overlie permeable fracture zones. Several straight stream and valley segments in the Sweetwater Creek area of Douglas County were found to be on rock having an average spacing of joints and fractures. None of the valleys was found to be associated with a zone of fracture concentration. Possibly, these valleys were localized over fracture zones that subsequently eroded away, leaving rock of average permeability. Depending on the depth of soil cover and the amount of rock exposed, it may not be possible to verify the presence of concentrated fractures by field examination. Zones of fracture concentration also occur in the south half of the area, but all that were identified in the field occupied hills and ridges and were not associated with valley development. The superimposed dendritic drainage in that part of the area seems to have greatly limited ,the localization of valleys by zones of fract~re concentration. Valleys localized over fracture zones may be limited to the headwaters areas of drainages where stream courses, draws, and other depressions were formed after removal of any preexisting cover and drainages were established under geologic control.

Permeable zones of fracture concentration commonly lie along straight valley segments that aline with gaps in ridges. 34 may explain why most high-yielding wells in the south part of the area that occupy valley settings are in headwaters areas. Early in the study the writers ob- served that many straight stream and val- ley segments in the south half of the area have a persistent strike of N. 35- w. 400 Near Milstead in Rockdale County, several linear valleys having this strike are coincident with or closely associated with diabase dikes .. Southwest of Atlanta, between Forest Park and Newnan, several straight stream and valley seg- ments also strike N. 35-40 w., but are not associated with diabase dikes. Be- cause of their nearly identical strike with the dikes, the writers considered the possibility that these valley seg- ments could have developed along the same system of tension joints that was in- truded by the diabase to the east and, therefore, could overlie zones of in- creased permeability. A test well was drilled in a linear valley formed by a segment of Camp Creek south of Riverdale, Clayton County (fig. 19), to check bed- rock permeability. The well, which is 600 ft deep, penetrated nearly solid gneiss and schist (Unit A) and yielded less than 10 gal/min. The results of this test provided the first hard evi- dence that these linear valleys were not localized over zones of fracture concen- tration and that their common strike was not a product of geologic control. This raised the question: could the parallel streams in the area having a common strike be a product of dendritic drainage? In an attempt to answer this question, topographic maps of parts of the Georgia Coastal Plain were examined to see whether in other areas of dendritic drainage, streams assume parallel courses and maintain a similar strike over large areas. The maps showed that in the Coastal Plain, streams have a common tendency to form several straight valley segments that follow essentially parallel courses. Thus, the parallelism of several straight valley segments in the south half of the GAR seems to be a normal development of dentritic drainage style and may not be related to bedrock permeability. Small-Scale Structures that Localize Drainage Development Small-scale structures that localize drainage development play a major role in determining the availability of ground water. The structures include joints, bedding or compositional layering, foliation, cleavage, and the axial planes of small folds. Such structures represent inhomogeneity in rocks and form planes of weakness that enhance the rapidity and depth of weathering, bringing about increases in permeability. Rocks generally are more permeable in directions parallel to these structures than across them. Preferential permeability in weathered schists and foliated rocks has been documented by Stewart (1964) and was observed during this study. (See section on contact zones under "Availability", this report.) As rocks weather, water moves through planar openings and establishes paths of circulation that increase the rate and depth of weathering. Weathering progresses rapidly and deeply along planes of bedrock weakness, tending to localize drainage development in much the same way as discussed for zones of fracture concentration. Where small-scale structures underlie and trend parallel to stream valleys, drainages, and draws that concentrate the flow of water, they can be avenues of greatly increased permeability. Wells drilled into drainages that flow parallel to structural features in the underlying bedrock commonly supply large yields. Relating small-scale structures to the topography and drainage is a very successful method of selecting high-yielding well sites. 35 0 I MILE ._E3_--J__.._F3_--J__.,.F='I._-_-_i_-.._-_-_-_-_-_-_-_-_-_-_-_-_-_-=._-_-_-_~ CONTOUR INTERVAL 20 FEET NATIONAL GEODETIC VERTICAL DATUM OF 1929 Figure 19. Topographic setting of the test well drilled in the linear valley formed by a segment of Camp Creek south of Riverdale, Clayton County. 36 Because small-scale structural features must localize drainage development in order to bring about significant increases in permeability, they are most useful in the north half of the report area where streams have developed under geologic control. They also may be useful in headwaters areas in the south. In the south half of the report area, some high-yielding wells are obtained by drilling in small draws and drainages in the headwaters areas of large streams. Commonly, where wells on hilltops and ridge crests furnished insufficient yields, successful wells resulted from moving to sites in the nearest draw or headwater drainage. Because these uppermost drainages formed after removal of any preexisting cover, their locations have been influenced by the underlying bedrock structure and, therefore, they occupy relatively permeable zones. Folds Rocks in the GAR were too ductile during periods of major deformation to develop open joints. The latest two fold sets, however, occurred after the rocks cooled and were under less pressure, producing open joints that are concentrated along the fold axes (Michael W. Higgins, U.S. Geological Survey, oral commun., 1981). The folds, which are east-west and north-south trending open fqlds ranging from less than 75 to more than 600 ft across, are recognizable in road cuts and quarries (fig. 20), from where they can be projected into low areas favoring deep weathering and increased recharge. In the absence of more productive features, concentrations of joints along fold axes in the right topographic settings may be capable of supplying large well yields. Shear Zones The Geologic Hap of Georgia (Georgia Geological Survey, 1976) shows a number of major shear zones south and southeast of Atlanta, in northern Spalding County and in Rockdale, Newton, and Walton Counties (plate 1). In relating well locations and yields to geology and structure, some of the highest yielding wells (100 gal/min to more than 200 gal/min) were found to be in these and other shear zones. Driller's logs of some of these wells report "broken rock" and "flint rock" in the wells, indicating that the wells penetrate shear zones. Other highyielding wells are near shear zones and also penetrate permeable rock, although details about the type of rock penetrated were unavailable. Many of the shear zones strike northeast and dip steeply to the southeast. They vary in length from less than 1 mile to about 7 miles. Although the geologic map shows shear zones to be continuous, field observations indicate that the longer shears may consist of a series of discontinuous zones that trend nearly parallel. The shear zones form prominent topographic lineaments and linears, generally consisting of low, narrow ridges flanking long, fairly straight valleys. The lineaments can be traced for miles in the field and are readily visible on topographic maps. Thicknesses of the shear zones are unknown, but the width of the associated valleys indicates that they may be as much as several hundred feet thick. The shear zones occur in a variety of rock types, though most are in granitic gneiss (Unit B). The sheared rock consists of two types: flinty crush rock and sheared country rock. The flinty crush rock is light-tan or buff colored, is very fine grained to cryptocrystalline, and breaks into small angular blocks. In hand samples it is easily distinguished from vein quartz. The more intensely sheared flinty crush rock weathers to small, flat, diamondshaped pieces produced by intersecting shear ~lanes. This is the single most consistent feature found in nearly all of the shear zones. Buff-colored flinty crush rock most commonly is associated with felsic granites and granitic 37 Figure 20. Concentrated jointing along the axis of a late fold. 38 r gneisses. Dark-gray to black flinty crush rock occurs in association with more mafic rocks, such as diabase. The sheared country rock generally shows little or no replacement mineralization. Shearing of biotite-rich gneisses commonly results in a rock having a schistose texture containing a large proportion of platy minerals (muscovite or biotite). Sheared amphibolites retain the same mineralogy but undergo abrupt textural changes that produce the previously mentioned diamondshaped fragments. Schist that has been sheared may weather into small diskshaped pieces and is referred to as "button schist." HIGH-YIELDING WELLS In this report, the term "high-yielding wells" refers to ones that supply a minimum of 20 gal/min, except in the belt extending from College Park through Atlanta, where the minimum yield is 50 gal/min. The maximum yields of the wells range from 35 to 470 gal/min, the wide range in yields resulting from differences in rock type, geologic structure, and topographic settings. The distribution of high-yielding wells in the report area is shown on plate 1. Data on more than 1,500 high-yielding wells in the GAR were obtained from files of the u.s. Geological Survey, local drilling contractors, and ground-water hydrologists, and from previous publications. The location of each high-yielding well used in this report was confirmed by field checking and plotted on topographic maps for determination of latitude, longitude, and topographic setting. Construction and yield data were confirmed, where possible, by interviews with well owners. About 400 reportedly high-yielding wells were excluded from use in this report because the wells could not be located within the alloted time or significant questions remained about the accuracy of yield or construction data. SELECTING SITES FOR HIGH-YIELDING WELLS Selecting sites for high-yielding wells requires a knowledge of the character of the underlying bedrock, the structural and stratigraphic features present, and the relation of these features to the topography and drainage. This knowledge generally is obtained by a foot traverse of the area, during which structural and stratigraphic features such as fault zones, contact zones, zones of fracture concentration, the dip and strike of foliation and layering, the strike and plunge of fold axes; and other clues to localized increases in bedrock permeability are plotted on a topographic map. Locating observed features on a topographic map is a good way to understand their relation to the topography and drainage. The appropriate method ( s) to use for selecting high-yielding well sites depends on (1) the quantity of water needed, (2) the topography and the drainage style of the area, (3) the rock type, (4) the types and character of structural and stratigraphic features present in the rock, and (5) imposed constraints, such as being limited to a small area or to specific pieces of property, or the requirement that the sites be near pipelines or other facilities. Site selection methods that can be applied to most combinations of geology, topography, and drainage are presented below. The reader also should understand that the successful siting of high-yielding wells in the GAR is not particularly good. Drilling of multiple wells to obtain required yields is common. Also, it should be recognized that some sites, for practical purposes, are virtually "barren" of ground water. Topography and Soil Thickness Because the yields of individual wells in the GAR vary greatly within short distances, estimating the potential yield of prospective sites can be very difficult. 39 Most methods for selecting well sites require a knowledge of geology and structure, which restricts their use primarily to hydrologists. A method was developed by LeGrand (1967) that utilizes only topography and soil thickness, and is suitable for use by nonhydrologists. The method provides a means for estimating, on a percentage basis, the chances of obtaining certain yields from prospective well sites in a variety of settings. The LeGrand ~1ethod "Although many factors determine the yield of a well, two ground conditions when used together serve as a good index for rating a well site. These conditions are topography and soil thickness. The ratings are based on the following statement: High-yielding wells are common where thick residual soils and relatively low topographic areas are combined, and low-yielding wells are common where thin soils and hilltops are combined. By comparing conditions of a site according to the topographic and soil conditions one gets a relative rating value. For example, the following topographic conditions are assigned point values: Points Topography 0 Steep ridge top 2 Upland steep slope 4 Pronounced rounded upland 5 Hidpoint ridge slope 7 Gentle upland slope 8 Broad flat upland 9 Lower part of upland slope 12 Valley bottom or flood plain 15 Draw in narrow catchment area 18 Draw in large catchment area "Figure 21 shows values for certain topographic conditions. Figure 22 shows rating values for soil thickness. The soil zone in this report includes the normal soils and also the relatively soft or weathered rock.

Site A, a pronounced rounded upland (4-point rating for topography in fig. 21) having a relatively thin soil (6-point rating for soil characteristics in fig. 22), has a total of 10 points. In table 5 the average yield for site A is 6 gal/min. This site has a 65-percent chance of yielding 3 gal/min and a 40-percent chance of yielding 10 gal/min. Site B, a draw or slight sag in topography (18-point rating) having a moderately thick soil (12-point rating), has a total of 30 points, an average yield of 50 gal/min, and a 73percent chance of yielding 25 gal/min. Referring to figure 23, we see that the 10-point site has less than 1 chance in 10 of yielding 40 gal/min, whereas the 30-point site has better than an even chance of yielding 40 gal/min. "Some topographic conditions of the region and a few topographic ratings are shown in figure 24. Wells located on concave slopes are commonly more productive than wells on convex slopes or straight slopes. Broad but slightly concave slopes near saddles in gently rolling upland areas are especially good sites for potentially high-yielding wells. On the other hand, steep V-shaped valleys of the gully type may not be especially good sites, and they should be avoided if surface drainage near the well is so poor that contamination is possible. "More difficulty is likely to occur in rating character of soil and rock than in rating topography. Everyone should be able to determine by observation if the soil is thin and if the soil is fairly thick (more than 10 soil and rock points), but the intermediate ratings are difficult to make. If the observer is unsure of the soil and rock rating above the 6-point (thin-soil) value, he may choose a 10-point value for the site with assurance that he is fairly correct. White quartz or flint is not considered a true rock in this report, because it persists in the soil zone; a quartz vein, in many cases, is considered to be a slightly favorable indication of a good well site. "The numerical rating system is not intended to be precise. One person may rate a particular site at 15 points, whereas another person may rate it at 17 points; such a small difference in rating would not be misleading. Almost everyone's rating will be within 5 points of an average rating for a site." Limitations.--LeGrand's method is especially well suited to the north half of the report area, where the topography and geology are closely related and the topographic setting and soil thickness are indicative of bedrock permeability. It can be applied there in every type of topographic setting, from the smallest draws and drainages to the larger stream valleys. The use of LeGrand's method should bring about a substantial increase in the percentage of high-yielding wells. w rGO~---r----~~-r~~~~-++---~_, :z:::> ~50r---~---+~~~--~~ aw:: 0.. w40r----+----~--~--~-r~~~~~~ z 0 _J _j 301-----+---1-1---.1~~--~..........-[.__-+r---...:H"'-I <[ (9 z - 20r----r~~r,~~~[.__r7L--+.~~~~ 0 _j w ):::: I 0 1------.~'---.ooL---,~-2f!C-~IIL-----:Ofi/F---"'"'211'"'""""'"?o. 10 15 20 25 30 TOTAL POl NTS EXAMPLE: A site with 16 points has 3 chances in 10 of yielding at least 30 gallons per minute and 6 chances in 10 of yielding 10 gallons per minute.

Countryside showing approximate ratings for topography. Numbers refer to figure 22. In the so ut h ha 1 f of the a r e a , t h e method probably will be most reliable in the uppermost headwaters areas of streams and along draws and drainages that flow down ridge slopes . In these areas , highyielding wells commonly result when a dry hole on a hilltop or ridge crest is abandoned in favor of a site in the nearest draw or saddle , or downslope midway between the hilltop and the draw . The larger superimposed streams and drainages are not necessarily located over zones of bedrock weakness and, therefore, the method may not be applicable in those areas. Contact Zones Between Rock Units of Contrasting Character Potentially permeable contact zones between rock units of contrasting character occur in the GAR wherever Units B, D, and F are in contact with Units A, C, and E and in some areas with Unit G. Some contact zones between Unit C and Units E, H, and G also may be permeable . Most contacts between these units are shown on 43 plate 1. Additional contact zones between different rock types within individual units can be found on detailed geologic maps that are available for parts of the area. (See References.) Field surveys also may reveal contact zones between individual rock layers not shown on the geologic maps. Identifying Contact Zones Permeable contact zones form between rock units that respond differently to weathering, such as granite and schist, gneiss and feldspathic schist, and massive homogeneous rock and highly foliated rock. The greatest permeability may occur where resistant rock (massive granite or gneiss) is overlain by rapidly and deeply w~athering rock (feldspathic schist). The more resistant rock may be characterized by fresh rock exposures and thin soil and may be somewhat higher topographically. The area underlain by the less resistant rock may lack exposures, have very deep soil, and be somewhat lower. Some contact zones occupy small linear depressions or show up as slight changes in slope between the two rock units. The contacts may follow small drainages or even streams, or they may cross drainages at various angles. Other contacts, particularly in the south half of the report area, have little if any surface expression and are visible mainly in road cuts and similar exposures. Selecting Well Sites High-yielding well sites should be selected so that the wells will penetrate contact zones at a depth of about 100 to 150 ft. Proper placement of the wells with respect to the dip of the contact zones is essential to avoid missing the zones completely or penetrating them at too great or too shallow a depth to obtain a large yield (fig. 25). The largest yields to wells can be expected where contact zones trend parallel to and underlie draws or drainages that are downgradient from sizable catchment areas. Contact zones croEsing broad, low areas covered by deep soil also can supply large well yields. In areas of poor exposure, it may be necessary to project contact zones into suitable topographic settings in order to select high-yielding well sites. Area of Application This method can be applied in most of the north half of the report area where drainage development and bedrock permeability are related. In the south half of the area, the method can best be applied to headwaters areas and to drainages and draws on the slopes of divide ridges. The development of these lateforming drainages probably followed the removal of any preexisting cover and thus, contact zones are more likely to have influenced drainage development. Contact Zones in Multilayered Rock Units Permeable contact zones in multilayered rock units are most likely to occur where different rock types alternate in layers a few feet to no more than a few tens of feet thick. Rock layers of suitable type and thickness are present in most areas underlain by Unit A and in some areas of Units C, D, E, and G. However, because the individual rock layers in these units are not shown on plate 1 and generally are not shown on geologic maps, they must be located and checked forsuitability by field surveys. In areas of poor exposure, it may be necessary to determine the character and thickness of the rock layers in road cuts, quarries, and similar exposures and project them along strike into favorable topographic settings. 44 0 , 85 02 0 , 33 37 0 , 85 00 0 I MILE F=-3r-~--~F=-3~~--~F=-3~~----------------, -CONTOUR INTERVAL 20 FEET NATIONAL GEODETIC VERTICAL DATUM OF 1929 A 1080' 5CC40 A' 1040' 1020' 1000' 980' 960' 940' VERTICAL SCALE GREATLY EXAGGERATED Figure 25. Well in contact zone between schist and granitic gneiss. Well SCC39 yields 100 gallons per minute from the contact zone. Well SCC40, which missed the contact zone, supplied about 1 gallon per minute. 45 Identifying Co1tact Zones Contact zones capable of supplying large well yields generally form between rock layers that respond differently to weathering, such as gneiss, schist, and amphibolite (Unit A). Permeable contact zones also may form between layers of feldspathic schist and graywacke or quartzite in Unit C, -between layers of schist or amphibolite and biotite gneiss in Unit D, and between different lithologies in Unit E. Increases in permeability generally are greatest in contacts that occupy topographic settings which concentrate the flow of ground water, such as in draws, drainages, and stream valleys. Selecting Well Sites Well sites should be located so that at a depth of 100 to 150 ft the wells will penetrate whatever contact zones project updip into the nearest streambed, draw, or area of deep soil (fig. 26). The best locations are those that increase ground-water circulation along the contact zones, as where rock layers strike parallel to local drainages. In such areas deep soil normally obscures the bedrock, requiring that the dip and strike of the rock layers be determined at nearby roadcuts or similar exposures. The largest well yields generally are obtained by drilling on the downdip side of streams or other drainages where the rock layers and drainage courses are parallel (fig. 26). It is important that well sites be placed downgradient from catchment areas large enough to supply adequate recharge. Area of Application This method is applicable mainly to the north half of the report area where bedrock weakness and drainage patterns are closely related. In the south half of the area, the method probably will be successful mainly in headwaters areas and in draws and drainages that flow off divide ridges, especially where the strike of the rock layers and drainage courses are parallel. Fault Zones Fault zones become permeable mainly where they bring into contact two or more rock types that respond differently to weathering, much the same as with contact zones. Examples would be faults that displace schist (Unit C) against granite (Unit F), amphibolite (Unit E) against schist (Unit C), or a highly foliated rock against a massive rock. Several faults are visible on detailed geologic maps available for parts of the report area. (See References.) Identifying Fault Zones Most fault zones possess characteristic features that aid field identification. These features include: (1) angular rock fragments in fresh exposures, or preserved as relicts in saprolite, (2) zones of intense shearing, (3) terminated rock units or layers, offset beds or layers, and abrupt changes in lithology, either parallel to or across the strike, (4) abrupt offsets of drainages or valleys and abrupt changes in linear topography, (5) haphazard mixing of two or more rock types in zones less than 10 ft to more than 100 ft wide, and (6) pegmatites and vein fillings such as quartz and halloysite (clay) concentrated in bedrock or saprolite. Recent faults may be recognized by the presence of vertical or near-vertical open fractures spaced 1 to 4 inches apart throughout a zone 10 ft to 30 ft wide. A 3- to 6-inch wide layer of fault gouge (rock flour or clay) may occur near the middle of the fault zone. 46 OEr"-"3-.--E.-:-3.---E.:-3-.-------------~IIMILE CONTOUR INTERVAL 20 FEET NATIONAL GEODETIC VERTICAL DATUM OF 1929 A VERTICAL EXAGGERATION X5 Figure 26. Wells tapping contact zones within multilayered rock unit. Well 13HH6 on downdip side of stream is 401 feet deep and yields 24 gallons per minute. Well 13HH15 is 660 feet deep and yields 6 gallons per minute. 47 Selecting Well Sites High-yielding well sites in fault zones are selected in much the same way as they are in contact zones. The sites should be located so the wells will penetrate inclined fault zones at a depth of about 100 to 150 ft. In broad fault zones, wells can be sited in low-lying areas within the zone, preferably in draws or drainages that parallel the fault. All well sites should be downgradient from catchment areas large enough to provide adequate recharge. Area of Application The method is most effective in the north half of the report area where there is a strong correlation between drainage development and bedrock resistance. In the south half of the area, the method may be successful in headwaters areas, especially where faults underlie and parallel drainage courses. Stress Relief Fractures Stress relief fractures seem to occur mainly in large bodies of granitic and biotite gneiss (Units Band D), but they also are important in units consisting of gneiss interlayered with schist (Unit A), schist interlayered with amphibolite (Unit A) and amphibolite-hornblende gneiss (Unit E). Stress relief fractures have been observed in quartz-mica schist and they may be a common occurrence in schist units having a high quartz content. Stress relief fractures also may occur at depth in granites (Unit F), although none were identified during this study. Identifying Stress Relief Fractures Because of their horizontal nature and depth of occurrence, the presence of stress relief fractures is not indicated by structural and stratigraphic features normally associated with increased bed- rock permeability. The only clue to their presence recognized thus far is topographic setting. Areas considered favorable for stress relief fractures include: A. Points of land formed by (1) two streams converging at acute angles (fig. 12B, C), (2) two subparallel tributaries entering a large stream (fig. 12A, D), and (3) land protruding into the wide flood plains of large streams (fig. 12E). In 1 and 2, the points of land generally are less than 2,000 ft across. B. Broad, relatively flat ridge areas, commonly on divide ridges, that are surrounded by stream heads (figs. 13 and 14). The wells are on the ridge crests and in the upper reaches of streams flowing off the ridges. Such areas are the sites of many towns and communities and, therefore, are centers of municipal and industrial pumpage. C. Broad valleys formed by the removal of large volumes of material relative to the land on either side (fig. 28). Selecting Well Sites Topographic settings considered to be favorable areas for stress relief fractures can be identified on topographic maps. On broad, relatively flat ridge areas and in wide places on divide ridges, both of which are surrounded by stream heads, well sites may prove successful on the ridge crests and in the upper reaches of streams flowing off the ridges. On points of land, successful well sites generally are on the ridge crests or the lower ridge slopes from about midway along the ridge to near the end of the land point. Most high-yielding wells on points of land projecting into wide flood plains are near the flood plains. Statistics show that a well depth of about 620 ft is needed to test the yield potential of each site. Horizontal fractures also have been identified in the north part of the area 48 beneath the broad valleys formed by the erosion of large volumes of material (fig. 28). Area of Application Stress relief fractures have been identified beneath broad ridge areas and on divide ridges surrounded by stream heads mainly in the south half of the area, but they also could occur in the north half. Relief fractures beneath points of land have been recognized only in the south part of the area. Horizontal fractures beneath broad valleys have been identified in the north part of the area, but whether they occur beneath such valleys in the south part is unknown. Zones of Fracture Concentration Zones of fracture concentration are likely to increase bedrock permeability in comparatively brittle rocks such as quartzite (Unit H), amphibolite and hornblende gneiss (Unit E), interlayered gneiss, schist, and amphibolite (Unit A), and possibly granite (Unit F). They are less likely to produce permeable zones in schist (Unit C), except where graywacke or quartzite forms a significant part of the unit. Identifying Zones of Fracture Concentration Zones of fracture concentration form linear features that appear as straight stream and valley segments; abrupt changes in valley alinement; the alinement of gulleys, small depressions, and gaps in ridges; abrupt changes in slope; and the alinement of areas having vigorous or stressed vegetation. In the south half of the area, many linear valleys are a product of dendritic drainage and are not necessarily associated with zones of fracture concentration. Selecting Well Sites Zones of fracture concentration may be less than 30 ft to about 200 ft wide. Thus, well sites must be on or as near as possible to the centerline of the fracture zone. The highest yielding wells generally are at the intersection of two fracture zones, which may be indicated by an abrupt change in valley trend or by the intersection of two valley segments (fig. 17). Sizable catchment areas upgradient from the well sites are needed to supply adequate .recharge and sustain large well yields. Area of Application The method is applicable mainly to the north half of the report area where characteristic topographic expressions can be used to identify zones of fracture concentration. Zones of fracture concentration probably are present in the south, but they are difficult to identify because of the prevalent dendritic drainage in that part of the area. Their presence may be detectable in headwaters areas where topographic development is more likely to reflect zones of bedrock weakness. Small-Scale Structures that Localize Drainage Development Small-scale structures represent inhomogenities in rocks that enhance the rapidity and depth of weathering and increase permeability. Increases in permeability generally are much greater in directions parallel to the small-scale structures than across them. This directional permeability tends to localize drainage development parallel to the small-scale structures. Where smallscale structures underlie and trend parallel to stream valleys, drainages, or draws that concentrate the flow of water, they can be avenues of greatly increased permeability capable of supplying large well yields. 49 Identifying Small-Scale Structures Small-scale structures associated with increased bedrock permeability include joints, bedding or compositional layering, foliation, cleavage, and the axial planes of small folds. Most small-scale structures are readily recognized on bedrock exposures and some are visible in saprolite. Structural data needed to select well sites are dip and strike of planar surfaces and the strike and plunge of fold axes. Generally, this type of data can best be obtained from field surveys of prospective sites, although detailed geologic maps provide structural data for parts of the area. (See References.) The relation of the small-scale structures to the topography can be determined by plotting the structural data on topographic maps. Selecting Well Sites The largest well yields can be expected from sites in stream valleys, draws, and drainages that parallel the strike of small-scale structures. Where planar structures are vertical or near vertical, as with many joint sets, the sites should be as near as practicable to the centerline of the drainage, taking into account the possibility of flooding. Where the structures are inclined, as is common with foliation and compositional layering, the most productive drilling sites may be on the downdip side of the drainages, provided the drainages are broad enough so that moving to that side does not require being on or near a steep slope or bluff, or on the nose of a ridge, no matter how small. Where possible, the sites should be downdip far enough so the well, at a depth of 100 to 150 ft, will penetrate whatever surfaces project upward into the bed of the drainage. A good combination might be a draw that parallels the strike of a welldeveloped set of joints, or the axial planes of minor folds, especially where the folds plunge in the downstream direction. Other good sites are in stream valleys and drainages that parallel the strike of the foliation, at points where tributary draws following cross structures such as joints enter at right angles on the downdip sides, or on both sides of the valleys. Of course, catchment areas of adequate size upgradient from the sites are needed to sustain large well yields. Where small-scale structures and drainages are not parallel, select sites in draws or stream valleys that are as nearly parallel as possible, staying well downgradient to insure adequate recharge. In selecting well sites, it is important to keep off any kind of crest, no matter how small or insignificant. This applies to cross ridges or ridge backs, and the noses of ridges, such as one that projects toward or into the flood plain of a stream. (This is not to be confused with much larger "points of land" described in a preceding section on Stress Relief Fractures). Where limited to a ridge top, always place the well site in a saddle or low area on the ridge top, preferably one that parallels some smallscale structure and that forms the head of a draw, no matter how slight the depression. Also, keep in mind that in a given rock type, the more gentle the slope, the softer, more readily weathering and more permeable the rock. Beneath steeper slopes, the rock is harder, less weathered, and generally less permeable. For this reason, the more gentle the slope, the larger the well yield may be. Area of Application This method is applicable to all of the north half of the report area. In the south half of the area, the method probably should be limited mainly to headwaters areas and to draws and drainages that flow off divide ridges and upland areas. To be effective, there should be a clear relationship between any topographic feature and the structure of the underlying bedrock. 50 Folds that Produce Concentrated Jointing Two sets of late folds in the GAR have open joints concentrated along their axes that should produce significant increases ih bedrock permeability. In favorable topographic settings, these zones of concentrated jointing should supply large quantities of water to wells. Identify~ng Late Folds Late folds that produce concentrated jointing along their axes are east-west and north-south trending symmetrical anticlines about 75 to 600ft across. The folds are most easily recognized on near-vertical bedrock exposures in road cuts and quarries, but they can be identified in natural exposures in stream valleys. They also may be recognized in cuts through saprolite. Selecting Well Sites Large well yields should be obtainable where zones of concentrated joints occupy topographic settings that favor increased ground-water circulation and recharge. Folds identified in road cuts and other exposures can be projected into low areas covered by deep soil, or into drainages and draws, preferably ones that parallel the fold axes. Because the greatest permeability will exist within a zone a few feet wide, wells should be centered as nearly as possible over the fold axes. Area of Application The method is applicable to the entire GAR. Shear Zones High-yielding wells are associated With major shear zones in Rockdale, Newton, Walton, and northern Spalding Counties. Smaller shear zones occur in other parts of the area and may supply large well yields. Identifying Shear Zones Major shear zones in Rockdale, Newton, Walton, and Spalding Counties are shown on plate 1. The shear zones, which vary from less than a mile to about 7 miles long, form prominent topographic lineaments, generally consisting of low, narrow ridges flanking long, fairly straight valleys. The lineaments can be traced in the field and are readily visible on topographic maps. The thickness of the shear zones is unknown, but the width of the associated lineaments indicates that they may be as much as several hundred feet thick. The shear zones occur in a variety of rock types, although most are in granitic gneiss (Unit B). Rocks within the shear zones consist of chert-like flinty crush rock and sheared country rock. Large permeabili.ty increases can be expected where the sheared rock has a high feldspar content. Selecting Well Sites The best sites for high-yielding wells should be in the linear valleys that overlie shear zones such as those shown on plate 1. Because the shear zones dip to the southeast, wells drilled near the middle or on the southeast sides of the valleys may produce the highest yields. Area of Application The major shear zones are in the south part of the area, but smaller shear zones occur throughout the GAR. Shearing is very common in the Brevard Fault Zone (Unit G) and may be responsible for highyielding wells in that feature. Small shear zones were observed in the north part of the area; and, where they occupy favorable topographic settings, they may supply large well yields, especially where they are in feldspathic rocks. 51 RELATION OF WELL YIELDS TO WELL DEPTHS It is estimated that there are more than 20,000 drilled wells in the GAR (W. A. Martin, Virginia Supply and Well Co., oral commun., 1978). Most of these wells were drilled for domestic or farm supplies, although a significant number were drilled for industrial supplies and to provide water for various commercial and public needs. These wells were located primarily for the convenience of the users, or were confined to readily available property or to areas near distribution lines and railroads. Most of the well sites were selected without regard to the suitability of geohydrologic conditions and thus, for the purposes of this study, are considered to be randomly located. The random selection of more than 20,000 drilled well sites in the GAR resulted in 1,165 wells, or approximately 5 percent, that are confirmed as being high yielding. 80 ,-------------------------------~ 60 (__/..) lLI 50 ~ u. 0 40 z1- lLI 0 30 0:: lLI a.. 20 To conclude that only about 5 percent of the wells drilled in the GAR had the potential of supplying high yields probably would, however, be incorrect. This is because most of the wells were intended for domestic and farm use and were drilled no deeper than was required to obtain the minimum acceptable yield of 2 to 10 gal/min. Thus, most of the wells are relatively shallow and did not test the full potential of each site. Had all of the wells been drilled deeper, a larger percentage likely would have been high yielding. Data obtained during this study show a strong correlation between well depths and yields. The belt extending from College Park northward through Atlanta is one area where data are available on both highyielding and low-yielding wells. In this belt, 40 percent of the industrial, commercial, and public supply wells furnish 50 gal/min or more; about 60 percent of these wells are 400 ft to more than 600 ft deep (fig. 27). In the same area, 82] PRIVATE WELLS [ [ ] INDUSTRIAL, PUBLIC SUPPLY, AND COMMERCIAL WELLS 1o0 ~~~~~~~~~~~~,~~~f~~~~ 20-50 50-100 YIELD, IN GALLONS PER MINUTE DEPTH, IN FEET Figure 27. Relation of well yields to depths in the belt from College Park through Atlanta. 52 only about 6 percent of the private wells furnish 50 gal/min or more; only about 10 percent of the private wells are as deep as 400 ft. Thus, there is a strong correlation between well depths and well yields, to a depth of about 600 ft. The data from wells in this belt indicate that the chances of obtaining a high yield from randomly located wells could be increased by consistantly drilling to depths of about 620 ft (table 9, Appendix). How this would apply to other parts of the GAR is not known, but it seems likely that deep drilling would increase the chances of obtaining large yields significantly beyond the 5-percent range. Drilling to this depth, of course, does not guarantee a high yield, as numerous wells 600 ft or more deep are reported to be dry and some wells 1,QOO to 1, 500 ft deep are low yielding. The well data indicate that drilling deeper than about 650 ft usually cannot be justified without supporting structural or stratigraphic evidence that indicates the presence of deeper openings. SAFE WELL YIELDS The safe yield of a well has been defined by Lohman (1972) as, "the amount of ground water one can withdraw without getting into trouble." In this definition, withdrawal may mean pumping a well nearly continuously, as is common with industrial and municipal supplies; seasonally, as for irrigation; or intermittently for prescribed periods each day, as to meet peak demands. Trouble may mean a number of things, including (1) running out of water, (2) declining yields, (3) muddying of the water supply during droughts, and (4) well interference. Depending on the well, the safe yield may not remain constant, but may vary With changing conditions. For example, the safe yield may temporarily diminish during a prolonged drought. Other conditions, such as interference from nearby Wells or the diversion of surface drain- age and subsequent loss of available recharge, may lower the safe yield of a well. Safe yields also may vary throughout the year between wet and dry seasons. Continuous monitoring of water levels in pumping wells is a good way to determine whether safe yields are being exceeded, and it affords an opportunity to adjust pumping rates as needed to maintain optimum water levels. Safe yield estimates on wells in the GAR generally are made from tests conducted at the time of drilling. Nearly all of the wells are drilled by the airrotary method and the yields are estimated by blowing compressed air through the drill column and measuring the volume of water that the air expells. This method can indicate safe yields of some wells but it provides no means for measuring the drawdown and recovery during testing. Drawdown and recov~ry data are needed to accurately estimate safe yields, so that wells will not be equipped with pumps whose capacities are too large. The safe yields of most wells can be estimated with reasonable accuracy from long-term pumping tests. These are tests in which the pumping rate is increased in steps or kept constant for several hours or days and the water level in the well is measured during both the pumping and the recovery phases of the tests. In general, the longer the pumping period, the more accurately safe yields can be estimated. The most accurate estimates normally are obtained from tests that run for 2 days or more, although useful estimates can be made from tests of less than 12 hours. Long-term pumping tests have been conducted on comparatively few wells in the GAR. Most of the tests were run on industrial or privately owned wells and the results were never published. Consequently, little information is available about the drawdown and recovery characteristics of wells in different topographic and geologic settings. 53 Test Wells Three test wells were drilled during this study to investigate the yield potential of different geologic settings and to learn the nature of water-bearing openings. Pumping tests were run on two of the wells to provide drawdown and recovery data needed to estimate safe yields. The test-well sites were selected in two settings: (1) a broad valley of a perennial stream formed by the erosion of a large volume of material (fig. 28) where stress relief fractures were believed likely to occur, and (2) a narrow valley eroded by a stream flowing across the strike of resistant rocks, the stream direction probably being joint controlled (fig. 32). The second site was of particular interest because valleys of the same character are common in that area, and should they prove to be suitable sites for high-yielding wells, they could supply significant quantities of ground water. Test Well 1 Test well 1 (8CC7) is in south Fulton County, on the flood plain of Bear Creek, a tributary of the Chattahoochee River (fig. 28). The area is underlain by moderately well-foliated biotite gneiss and minor mica schist (Unit B) that weathers very deeply. Bear Creek approximately parallels the strike of the foliation, which dips southwest at about 60. The well site is near the Brevard Zone, but the rocks have not been sheared or mylonitized as have rocks within the zone. Well statistics are: Depth Casing depth Diameter Static water level Yield (determined by compressed air test) 256 ft 56 ft 6 in. 3.85 ft below land surface 100 gal/min (about half of which was from the saprolite) Casing in test well 1 was mistakenly set too shallow on a resistant rock layer in the saprolite and the well caved during development. Therefore, the well could not be tested and was used as an observation well for the pumping test done on test well 2 (8CC8). Test Well 2 Test well 2 (8CC8), about 15 ft north of test well 1 (8CC7), is in the same geologic and topographic setting (fig. 28). Well statistics are: Depth Casing depth Diameter Static water level Yield (determined by compressed air test) 243 ft 78 ft 6 in. 3.85 ft below land surface 45 gal/min Most of the well water was derived from fractures at depths of 103 and 176 ft. A step-drawdown test was conducted first to determine the approximate pumping rate that could be used in the longterm test. Pumping was done in steps of 10, 20, and 30 gal/min (fig. 29). A pumping rate of 30 gal/min for a period of 135 minutes produced a drawdown of 20 ft. Recovery of the water level after pump shutdown was rapid, being about 90 percent complete after 5 minutes and complete after 100 minutes. From these data, it was concluded that a pumping rate of 36 gal/min (the maximum capacity of the pump) would be suitable for the long-term test. During the long-term test, a pumping ra~e of 36 gal/min over a period of 1,160 minutes'(19.3 hours) produced a drawdown of 31 ft, to a depth of 32 ft below land surface (fig. 30). Recovery of the water level after pumping ceased was rapid; recovery was about 93 percent complete after 10 minutes and essentially complete after 300 minutes. 54 0 '' 33 35 33 0 33 ' 0F.=-l~--~F~=--l ~--F-,------=-1-------------~1I MILE CONTOUR INTERVAL 20 FEET NATIONAL GEODETIC VERTICAL DATUM OF 1929 Figure 28.

Drawdown and recovery curve for long-term pumping test on test well 2 ( 8CC8). 56 According to LeGrand (1967, p. 4), the increase in yield of a well in crystalline rocks is not directly proportionate to an increase in drawdown of the water level. Rather, a yield of about 80 percent of the total capacity of the well results from lowering the water level only about 40 percent of the available drawdown.1 In test well 2 (8CC8), a pumping rate of 36 gal/min caused a decline in the water level of only about 30 percent of the available drawdown (to the top of the highest water-bearing fracture), indicating that.the well was being pumped at about 60 percent of capacity (fig. 31). In light of the rapid recovery of the water level after pumping ceased, and the availability of constant recharge in the valley of a perennial stream, 36 gal/min probably is a conservative safe yield for this well. Continuous monitoring of the water level in the well during production would reveal whether that yield stresses the well and the pumping rate could be adjusted accordingly. 1 LeGrand (1967, P 4) referred to the available drawdown as the total depth of the well. However, in test well 2 (8CC8) the total yield is derived from only two waterbearing fractures. Thus, it would be undesirable to draw the water level down below the uppermost water-bearing fracture because doing so could lead to iron encrustation and reduced yield. In test well 3 (9DD1), discussed next, the maximum yield would be obtained by drawing the water level down to the single water-bearing fracture. Therefore, the available drawdown in these wells is considered to be the depth of the highest waterbearing fracture, thus making the percentages of relative yield somewhat conservative. Test Well 3 Test well 3 (9DD1), in Douglas County, is on the bank of a small perennial stream that flows southeast in a narrow valley at right angles to the strike of the rocks (fig. 32). The stream is a tributary of the Chattahoochee River, which is about 0.3 mile away. The well penetrates a muscovite biotite gneiss (Unit G) containing numerous quartz veins. The well is in an area of rolling to hilly topography, which is strongly controlled by rock structure. Well statistics are: Depth Casing depth Diameter Static water level Yield (determined by compressed air test) 248 ft 12 ft 6 in. 53 in. below land surface 40 gal/min Nearly all of the yield was derived from a single fracture at a depth of 64 ft. The step drawdown test conducted on this well used pumping rates of 21, 25, 30, and 40 gal/min (fig. 33). A pumping rate of 40 gal/min over a period of 340 minutes lowered the water level to a depth of 56 ft below land surface, which is about 88 percent of the distance to the water-bearing fracture that supplies the well. According to LeGrand (1967, p. 4), 40 gal/min should represent about 98 percent of the available yield of this well, indicating that it probably exceeds the safe yield. However, the rapid recovery of the water level after pumping ceased and the ready availability of recharge in the valley of a perennial stream, suggests that the well might be able to sustain this yield, at least on an intermittent schedule. Therefore a pumping rate of 40 gal/min was selected for the long-term test to see how it would affect the drawdown and to further evaluate the yield capabilities of the well. 57 0 80 ...J 1.1.1 > >1.1.1 ~ 60 1.1.1 0::: LL.. 0 40 1.1.1 C) < 1z - 1.1.1 (.) 0::: 1.1.1 20 0.. 0~~---L--J---L-~--~--~--L-~--~ 0 20 40 60 80 100 PERCENTAGE OF DRAWDOWN OF WATER LEVEL Figure 31.

The topography and drainage are closely related to bedrock permeability and therefore conventional methods for locating highyielding well sites apply to most of the area. The south half of the area, on the other hand, has superimposed dendritic drainage style in which streams developed independently of the underlying bedrock. There, the topography and drainage are poorly related to bedrock permeability and high-yielding wells commonly occupy ridge crests, steep slopes, and bare-rock areas normally considered sites having low yield potential. 2. Geologic and topographic studies of 1,051 high-yielding well sites revealed that large well yields are available only where aquifers possess localized increases in permeability. This occurs mainly in association with specific structural and stratigraphic features: (1) contact zones between rock units of contrasting character and within multilayered rock units, (2) fault zones, (3) stress relief fractures, (4) zones of fracture concentration, (5) small-scale geologic structures that localize drainage development, (6) folds that produce concentrated jointing, and ( 7) shear zones. Methods were developed for selecting high-yielding well sites using these structural and stratigraph features. 3. Borehole sonic televiewer logs revealed that high-yielding water-bearing openings in granitic gneiss (Unit B), biotite gneiss (Unit D), gneiss interlayered with schist (Unit A), and quartzmica schist (Unit C) consist mainly of horizontal or nearly horizontal fractures 1 to 8 inches in vertical dimension. The writers believe these are stress relief rractures formed by the upward expansion of the rock column in response to erosional unloading. Core drilling at two well sites confirmed the horizontal nature of the fractures and showed no indication of lateral movement that could be interpreted as faulting. Wells that derive water from horizontal fractures characteristically remain essentially dry during drilling until they penetrate the high-yielding fracture. The high-yielding fractures are at or near the bottom of wells because: (1) the large yields were in excess of the desired quantity and, therefore, drilling ceased, or (2) in deep wells yielding 50 to 100 gal/min or more the large volume of water from the fracture(s) "drowned out" the pneumatic hammers in the drill bits, effectively preventing deeper drilling. Twenty-five wells in the report area are known to derive water from bottom-hole fractures, all of which are believed to be horizontal stress relief fractures. The wells occupy a variety of topographic settings, including broad valleys, ridge crests, steep slopes, and bare-rock areas, because horizontal fractures are present beneath uplands and lowlands alike. Wells deriving water from stress relief fractures have much greater average depth than wells reported from other crystalline rock areas. Many of the wells are 400 to 600 feet deep and derive water from a single fracture at the bottom of the hole. 4. Contrary to popular belief, many wells in the GAR are highly dependable and have records of sustaining large yields for many years. Sixty-six mainly industrial and municipal wells have been pumped continuously for periods of 12 to more than 30 years without experiencing declining yields. 5. Large supplies of ground water presently are available in the area. Most of the 1,165 high-yielding wells inventoried during the study supply from 40 to more than 200 gal/min. The distribution of these wells with respect to topography and geology indicates that most were located for the convenience of the users and that the large yields resulted mainly from chance, rather than from thoughtful site selection. By em- 66 playing the site selection methods outlined in this report, it should be possible to develop large supplemental ground-water supplies in most of the area from comparatively few wells. 6. Well water in the area generally is of good chemical quality and is suitable for drinking and most other uses. Concentrations of dissolved constituents are fairly consistent throughout the area, and except for iron and manganese, rarely exceed drinking water standards. However, in some more densely populated areas, aquifer contamination from septic tank effluent is a significant problem. SELECTED REFERENCES Atkins, R.
