Summary
On April 23, 1997, the Georgia Environmental Protection Division (EPD) issued its Interim Strategy for Managing Salt Water Intrusion in the Upper Floridan aquifer of Southeast Georgia. The Interim Strategy, which will apply to 24 coastal counties of Georgia and affect adjacent parts of South Carolina and Florida, specifically calls for EPD to:
Conduct expanded scientific and feasibility studies to determine with certainty how to permanently stop the salt water intrusion moving towards Hilton Head Island, South

Carolina and how to prevent the existing salt water intrusion at Brunswick, Georgia from worsening As part of the Interim Strategy, the EPD is conducting an investigation of the Upper Floridan aquifer at Brunswick, Georgia. When the investigation of the Upper Floridan aquifer at Brunswick, Georgia is completed, the results are expected to partially answer one group of questions posed by the Upper Floridan Technical Advisory Committee (TAC):
Where are the known locations where salt water is entering the Upper Floridan aquifer and why is salt water entering at these locations?
Can a long-term monitoring system be established so that changes in salt water intrusion can be monitored?
To achieve these results, EPD entered into a contract with LAW Engineering and Environmental Services, Inc. (LAW) to design and construct two 900'-1,000' salt-water monitoring wells in the Upper Floridan aquifer of Brunswick, Georgia, and to continuously monitor water levels and salinity until June 30, 2006. The general objective of the proposed project is to provide quarterly electronic reports on the chloride content in these wells to EPD and the United States Geological Survey (USGS).
The first well (TW34H504/505) was completed before December 31, 2001. The well designation TW34H504 corresponds to the upper permeable zone and TW34H505 corresponds to the lower permeable zone. In the final report issued for this well, the designation TW34H504/505 corresponds to the combined well facility constructed on the Southside Baptist Church property. A second well (TW33H324/325) was completed before March 31, 2002. The well designation TW33H324 corresponds to the upper permeable zone and TW33H325 corresponds to the lower permeable zone. In the final report the designation TW33H324/325 corresponds to the combined well facility constructed at a Georgia Pacific property location.

1.0 BAckground and INTRODUCTION
On April 23, 1997, the Georgia Environmental Protection Division (EPD) issued its Interim Strategy for Managing Salt Water Intrusion in the Upper Floridan aquifer of Southeast Georgia. The Interim Strategy, which will apply to 24 coastal counties of Georgia and affect adjacent parts of South Carolina and Florida, specifically calls for EPD to:
Conduct expanded scientific and feasibility studies to determine with certainty how to permanently stop the salt water intrusion moving towards Hilton Head Island, South Carolina and how to prevent the existing salt water intrusion at Brunswick, Georgia from worsening
As part of the Interim Strategy, the EPD is conducting an investigation of the Upper Floridan aquifer at Brunswick, Georgia. When the investigation of the Upper Floridan aquifer at Brunswick, Georgia is

completed, the results are expected to partially answer one group of questions posed by the Upper Floridan Technical Advisory Committee (TAC):



Where are the known locations where salt water is entering the Upper Floridan aquifer

and why is salt water entering at these locations?



Can a long-term monitoring system be established so that changes in salt water intrusion

can be monitored?

To achieve these results, EPD entered into a contract with LAW Engineering and Environmental Services, Inc. (LAW) to design and construct two 900'-1,000' salt-water monitoring wells in the Upper Floridan aquifer of Brunswick, Georgia, and to continuously monitor water levels and salinity until June 30, 2006. The general objective of the proposed project is to:

... provide quarterly electronic reports on the chloride content in these wells to EPD and the United States Geological Survey (USGS).

2.0 GENERAL APPROACH

As specified in the EPD Scope of Work, the work performed in phase 2 of this project involved the drilling, logging, and initial monitoring of a salt-water monitoring well in the Upper Floridan aquifer in Brunswick, Georgia. The monitoring well was drilled and constructed by a Georgia-licensed water well contractor (Woodrow Sapp Water Well Contractor, Inc.). The Southside Baptist Church site was selected (see Figure 1) and permission for drilling was obtained by EPD. The well was cased off through the Miocene and younger confining units and completed as an open hole well in two separate permeable zones within the Upper Floridan aquifer. The well was geophysically logged prior to completion. Water level and conductivity measuring instruments that are capable of making digital measurements a minimum of once per hour were installed downhole in each of the two zones. Upon completion and final instrumenting of this well, LAW prepared a draft report describing and illustrating site geologic conditions (including lithologic and geophysical logs), stratigraphic and hydrostratigraphic identifications, "as-built" conditions, instrumentation settings, and preliminary water level and salinity data. After review of this draft report by the EPD, LAW prepared the necessary modifications to submit this final report. In accordance with EPD's March 12, 2001 revised work plan, monitoring of the upper-water bearing zone will continue until December 31, 2005, and monitoring of the lower water-bearing zone will continue for a minimum of six continuous months after well completion. LAW will submit quarterly reports of water level and salinity data in digital format to EPD and the USGS for the calendar years 2002, 2003, 2004, and 2005. Each report will provide a short narrative description and water level and salinity data in a graphical format.

In accordance with the EPD Scope of Work, this first well (TW34H504/505) was completed before December 31, 2001. Well designation TW34H504 corresponds to the upper permeable zone and TW34H505 corresponds to the lower permeable zone. In this report the designation TW34H504/505 corresponds to the combined well facility constructed at the Southside Baptist Church location.

3.0 Drilling AND Well Construction METHODS

Prior to initiating field work, LAW visited the Georgia District of the Water Resources Division of the U.S. Geological Survey (USGS) and the Georgia Geologic Survey (GGS) to review relevant files, data, and publications and to discuss technical matters concerning geology, hydrogeology, well construction and water quality within the Floridan aquifer in the Brunswick area. Following these meetings, LAW discussed drilling strategies with the drilling subcontractor. Based on these meetings, LAW prepared and presented to EPD for approval the project design for well drilling, construction, and instrumentation (Phase 1 of this project).

GEOLOGY

The geology, to a depth of 1,000 feet, was studied from publications and unpublished government records to provide site-specific geologic and hydrogeologic interpretation for the Southside Baptist Church site. To accomplish this, LAW obtained lithological and geophysical logs and viewed televiewer recordings of various wells located in the vicinity of the proposed drill site. The location of the first deep monitoring well (TW34H504/505) at the Southside Baptist Church site was confirmed on July 12, 2001, by the GGS.

Southside Baptist Church Drill Site

The lithology encountered at the Southside Baptist Church drill site is summarized in Table 1. Well 34H504/505 was drilled to a depth of 1,000 feet. The lithologic log is presented in Appendix A, and the geophysical logs are presented in Appendix B.

The geophysical logs from Well TW34H504/505 exhibit a reasonable correlation with the lithological log from this well. The base of the Miocene and younger formations is noted by a "C-marker" on gamma-ray logs and the base of the Oligocene is marked by the presence of a "D-marker" on gamma-ray logs (Jones and Maslia, 1994). At Well TW34H504/505, the "C-marker" is present at a depth of 568 feet and also represents the horizon at which the top of the Oligocene Suwannee Limestone is encountered. The Suwannee Limestone extends to a depth of 592 feet, as noted by a "D marker" (Jones and Maslia, 1994). This marker also represents the horizon where the upper Eocene Ocala Limestone is encountered. The Ocala Limestone extends to approximately 921 feet where the middle Eocene Avon Park Formation is encountered.
Using gamma-ray logs, this geologic framework can be correlated to other wells around the Southside Baptist Church drill site. The nearest well to the Southside Baptist Church drill site is Well 34H100, a 786-foot deep well located 400 feet to the southeast of TW34H504/505. Based on the geophysical logs for Well 34H100, the base of the Miocene and younger formations is at a depth of 570 feet and the base of the Oligocene Suwannee Limestone is at a depth of 595 feet in this well.
LOCAL HYDROGEOLOGY
In the Brunswick area, the general hydrostratigraphy consists of a surficial aquifer, the Upper and Lower Brunswick aquifers, and the Upper and Lower Floridan aquifers, each separated by distinct semiconfining units (Jones and Maslia, 1994). Since the Miocene and younger formations were cased off in monitoring well TW34H504 and the well did not penetrate to the Lower Floridan aquifer, only the hydrogeology of the Upper Floridan aquifer was studied. The top of the Upper Floridan aquifer coincides with the C-marker at the top of the Oligocene Suwannee Limestone (Clarke and others, 1990), and the base is within the top part of the middle Eocene dolomitic limestone of the Avon Park Formation (Jones and Maslia, 1994).
In the Brunswick area, the Upper Floridan aquifer is confined at the top by Miocene silty clay and dense, phosphatic limestone or dolostone (Clarke and others, 1990) and is confined at the base by dolomitic limestone that occurs between 1,000 and 1,050 feet (Wait and Gregg, 1973). The Upper Floridan aquifer in the Brunswick area consists of an upper and lower water bearing, or permeable, zone (Wait and Gregg, 1973). The two permeable zones are separated by a low-permeability, semiconfining, upper Eocene dolostone unit that partially restricts flow between the zones (Clarke and others, 1990). The upper zone is recognizable on geophysical logs by a series of "kicks" to the left on spontaneous potential (SP) logs and to the right on resistivity logs and can yield up to 70% of the water to wells that penetrate both zones (Wait and Gregg, 1973). The lower zone, which is typically cavernous (Wait and Gregg,

1973), can be discerned using caliper logs in conjunction with acoustic televiewer logs (Jones, 2001). It may also be possible to discern the lower zone by a similar, yet discrete, series of SP and resistivity "kicks" exhibited in the upper zone. The entire Upper Floridan aquifer at Well 34H337 (located approximately 2,000 feet north of Well TW34H504/505) has an average transmissivity and storativity of 1.4 million gallons per day per foot (gpd/ft) and 0.0005, respectively (Wait and Gregg, 1973).
Southside Baptist Church Drill Site
The hydrogeology of the Upper Floridan aquifer encountered at the Southside Baptist Church well site was interpreted from geologic and geophysical data obtained during drilling of the well.
The top of the Oligocene (base of the "C-marker") was encountered at approximately 568 feet below ground surface (bgs) and marks the top of the Suwanee Limestone. The Oligocene-Eocene boundary ("D-marker") was encountered at 592 feet bgs, and marks the bottom of the Suwanee Limestone and top of the upper Eocene Ocala Limestone. The upper-middle Eocene boundary between the Ocala Limestone and Avon Park Formation was encountered around 920 feet bgs at the contact of limestone and dolostone. The upper Floridan aquifer includes the Suwanee Limestone, Ocala Limestone and Avon Park Formation and extends from 570 feet bgs to below well termination at 1000 feet bgs.
UPPER FLORIDAN SALT-WATER MONITORING WELLS Prior to drilling at the TW34H504/505 location, LAW secured a work area that roughly measured 100 by 150 feet. The site was secured with six-foot high chain link fencing and sanitary facilities were provided. Well construction began on September 19, 2001 and was completed on November 17, 2001.
Drilling Methods and Well Construction To construct the Upper Floridan salt-water monitoring well at the Southside Baptist Church site (TW34H504/505), three casings were set at depths that corresponded to significant geologic horizons. The casings included a 20-inch diameter outer surface casing for upper borehole stability, a 14-inch diameter inner casing installed to 585 feet, and an 8-inch diameter well casing installed to 831 feet. Initially, a 12-inch diameter pilot hole was drilled (using mud rotary methods) into surficial sediments until a suitable geologic horizon upon which to set the 20-inch surface casing was encountered (this horizon is typically encountered at a depth between 60 and 150 feet in the Brunswick area, and was encountered at a depth of 55 feet below ground surface (bgs) at TWH34H504/505). After this horizon was encountered, the pilot hole was reamed out to a 24-inch diameter borehole to this depth using mud rotary drilling techniques. To stabilize the boring, 55 feet of 20-inch surface casing constructed of standard steel was installed within the 24-inch boring and grouted along the entire length with Type II neat cement grout (ASTM C 150 Type II). The surface casing was grouted by placing cement directly into the annular space between the borehole wall and the casing, while pumping mud from the bottom of the annular space.
Following installation and grouting of the 20-inch casing, a nominal 19-inch diameter boring was advanced to the top of the Upper Floridan aquifer using mud rotary drilling techniques. Near the

completion of the nominal 19-inch diameter borehole, LAW contacted the EPD to provide downhole geophysical logging services of the Miocene deposits. Downhole digital SP, resistivity, gamma, caliper, and temperature logs were collected on September 28, 2001. The logs are presented in Appendix B. Following the geophysical logging, a 14-inch standard steel casing was installed within this borehole to a depth of 585 feet bgs. This depth roughly corresponds to the top of the Ocala Limestone, where the first continuous competent limestone formation was encountered at 592 feet bgs. The annular space around the casing and the borehole wall and the surface casing was cemented its entire length by pressuregrouting Type II neat cement grout through the inside diameter of the 14-inch steel casing.
Next, a 9-inch diameter pilot boring was advanced into the limestone using reverse air rotary drilling techniques. The nominal 9-inch diameter boring penetrated the Upper Floridan aquifer and terminated at an approximate depth of 1000 feet at the base of the Upper Floridan aquifer at the Southside Baptist Church drill site. Near the completion of the nominal 9-inch diameter borehole, LAW contacted the EPD and the USGS to provide downhole geophysical logging services. Downhole digital SP, resistivity, gamma, caliper, acoustic velocity/porosity and temperature logs were collected by the EPD on October 11, 2001. The logs are presented in Appendix B. LAW, EPD, and the USGS reviewed logging results and participated in selecting the monitoring zones for the upper and the lower permeable zones of the Upper Floridan aquifer at well TW34H504/505.
A 13.5-inch diamter bit was used to ream-out the pilot boring to a depth of 835 feet bgs, which corresponds to the top of the lower permeable zone. Prior to this activity, coarse sand was tremied down the borehole to fill the entire length of the lower permeable zone in order to prevent materials produced from the subsequent drilling and grouting operations from entering the zone. An 8-inch standard steel casing was then installed within the nominal 13.5-inch borehole to a depth of 831 feet bgs, terminating near the top of the lower permeable zone. Centralizers were installed at the following locations above the bottom of the 8-inch casing: 2.5, 21, 38 and 80 feet. The remaining 42-feet long sections of pipe had a half-moon type centralizer welded 4 feet from the top of the section and staggered with respect to each other. The 8-inch casing was pressure grouted from a depth of 841 feet bgs up to 759 feet using Type II neat cement grout. After allowing the grout to harden for four days, the concrete float shoe and cement plug were drilled out using a 7-inch bit. The sand-filled 9-inch open hole was then cleaned-out using an air-lift method. This method of completing the monitoring wells was used so the grout seal between the upper and the lower permeable zones was not compromised by subsequent drilling operations. As constructed, the upper monitoring zone designated as TW34H504 extends from 606 to 759 feet bgs, and the lower monitoring zone designated as TW34H505 extends from 841 to 1,000 feet bgs. The static water level at the site is above ground surface; therefore, the well was constructed to allow the temporary "shut-in" of the well during non-drilling times so that the well could not flow. Well completion details are summarized on Figure 2 and on the lithologic log in Appendix A.
LAW oversaw all drilling activities at the drill site. During drilling operations for the well, LAW collected cuttings at a minimum of 10-foot intervals and maintained records of drilling progress and drilling conditions. Cutting samples from the well were collected in two sets and one set was provided to the USGS. The site geologist described the lithology of the cuttings using the Unified Soil Classification and

the USGS lithologic classification system. During drilling and well installation, the site geologist was in continuous communication with both the Project Manager and the Principal Investigator regarding progress of the project.
Well development procedures of the lower zone included air lifting for two hours to remove larger solid material from the test well. Development continued until "clear" water was produced and a water quality parameter (conductivity) stabilized. The upper zone was developed by allowing the well to flow for an 8hour period until "clear" water was produced and a water quality parameter (conductivity) stabilized. Drilling fluids produced during reverse air rotary drilling and development were treated using a trailermounted particulate matter filter system with a 400-gallon per minute capacity. This filter was used in conjunction with baffled settling tanks so that turbid water did not enter any surface water body. This particulate matter filter system was trailer-mounted with two primary filters (100 micron) that could be operated either in parallel or series and a bank of four polishing filters (25 to 50 micron). The water was then conveyed away from the well site so that the water did not damage the site. Piping, hay bales, and silt fencing were used as necessary to accomplish this conveyance.
Well TW34H504/505 was completed at land surface with a four-inch thick concrete pad with dimensions of five feet by five feet. The casing of the well was left at a height of three feet above the pad to accommodate the installation of valves to control artesian flow. The drill site was restored after completion of all drilling operations. Site restoration included removal of all drilling equipment and drilling debris, filling mud sumps and ruts created by drilling equipment, and seeding with a lowmaintenance grass. An as-built schematic and photographs of the completed well head are shown in Appendix C.
1.0 sampling Methods
The well was sampled so that in-situ conductivity measurements could be related to the water samples obtained from the wells. After collection, the water samples from each zone were analyzed by an EPD laboratory for TDS and chlorides. The analyses are included in Appendix E. The well was allowed to free-flow to withdraw water from the test well at each zone to be monitored. As the well flowed, the water quality parameters of pH, temperature, and specific conductivity were measured, and water samples were taken after the parameters stabilized.
2.0 long-term monitoring methods
Water Level Measurements Two Hydrolab Diver water-level loggers were installed to provide measurements of potentiometric head changes in the monitoring well. An accuracy of +/- 0.1 foot can be achieved by the water-level loggers used in the well. The instruments are programmed to record the head once per hour. The water-level loggers were initially installed for the December 2001 monitoring period to depths of 20 feet bgs in both the upper and lower monitoring zones. The logger installed in the upper monitoring zone is currently set at a depth of approximately 10 feet bgs and the logger in the lower monitoring zone is currently set at approximately 7 feet bgs. The dataloggers were reset to the shallower depths to prevent water pressure from exceeding the maximum rated range of the instruments in the event of significant increases in water level. Transducer settings with minimal depth of water cover enabled LAW to select

pressure transducers with lower pressure ratings. Since instrument accuracy is a percentage of pressure rating, application of lower pressure on the tranducers enabled LAW to use transducers with increased accuracy for measuring pressure. Information and specifications of the installed instruments are presented in Appendix D.
Salinity Measurements A datalogger/salinity measurement device was installed to monitor salinity in each zone. A Solinst Reelogger with a downhole conductivity probe was installed to monitor the upper zone, while a Hydrolab MiniSonde 4A was installed to monitor the lower zone. The measurement devices operate by measuring conductivity as a surrogate of salinity. Calibration of each device was conducted in accordance to the manufacturers instrument specifications. The instruments were programmed to record a conductivity measurement once per hour. The conductivity measurement devices are set near the mid-depth of the zone to be monitored (670 feet bgs in the upper zone, and 920 feet bgs in the lower zone). The Hydrolab MiniSonde, which has internal datalogging capability, is suspended on a stainless steel cable. The conductivity probe for the Solinst Reelogger monitoring device in the upper zone is raised and lowered through a 1-inch observation riser and screen located in the annulus between the 14-inch open hole and the 8-inch casing. Data from the Hydrolab lower zone measurement system will be downloaded on a monthly basis by lifting the MiniSonde to the surface. Retrieval of the device is accomplished by manually reeling in the stainless steel cable. Once at the surface, the data can be downloaded from the MiniSonde to a laptop computer. The MiniSonde will be calibrated while at the surface. Data from the Solinst upper zone measurement system will be downloaded on a monthly basis from the surface-mounted Reelogger datalogger unit. The Solinst probe will be lifted to the surface and calibrated and checked each month. Retrieval of the down-hole probe is accomplished by manually reeling in the data transmission cable, which contains an integral safety cable. Information and specifications of the installed instruments are presented in Appendix D.
3.0 reporting to epd
In accordance with the March 12, 2001 Scope of Work issued by the Georgia EPD, LAW is contracted to monitor the upper water-bearing zone (TW34H504) until December 31, 2005, and monitor the lower water-bearing zone (TW34H505) for a minimum of six continuous months after well completion, or as directed by EPD. LAW will submit quarterly reports of water level and salinity data to EPD and the USGS, via e-mail, for the calendar years 2002, 2003, 2004, and 2005. Each report will provide a short narrative description and water level and salinity data in both a tabular and graphical format. The yearly reports shall be provided no later than 15 days after the end of each quarter, which shall be March 31, June 30, September 30, and December 31 of each year.
This site report also includes monitoring results for 2001, which are presented in Appendix E. These results include water level monitoring data from the Hydrolab Divers, suspended in the annular space between the 14-inch and 8-inch casings (upper zone) and inside the 8-inch casing (lower zone), conductivity data from the Solinst Reelogger conductivity probe suspended at 670 feet bgs at the midpoint of the upper monitoring zone and from the Hydrolab MiniSonde suspended at 920 feet bgs at the mid-point of the lower zone, and barometric pressure data from the Hydrolab Diver installed inside the protective well house. The data series for the Hydrolab MiniSonde was terminated prematurely after

approximately three days of measurement due to a low battery condition in the MiniSonde. The Minisonde was returned to Hydrolab for repairs, where a failure of the internal battery was discovered. The MiniSonde has been repaired by Hydrolab and is now operating properly. 4.0

1.0 BACKGROUND AND INTRODUCTION

August 2002

On April 23, 1997, the Georgia Environmental Protection Division (EPD) issued its Interim Strategy for Managing Salt Water Intrusion in the Upper Floridan aquifer of Southeast Georgia. The Interim Strategy, which will apply to 24 coastal counties of Georgia and affect adjacent parts of South Carolina and Florida, specifically calls for EPD to:

Conduct expanded scientific and feasibility studies to determine with certainty how to permanently stop the salt water intrusion moving towards Hilton Head Island, South Carolina and how to prevent the existing salt water intrusion at Brunswick, Georgia from worsening
As part of the Interim Strategy, the EPD is conducting an investigation of the Upper Floridan aquifer at Brunswick, Georgia. When the investigation of the Upper Floridan aquifer at Brunswick, Georgia is completed, the results are expected to partially answer one group of questions posed by the Upper Floridan Technical Advisory Committee (TAC):
Where are the known locations where salt water is entering the Upper Floridan aquifer and why is salt water entering at these locations?
Can a long-term monitoring system be established so that changes in salt water intrusion can be monitored?

To achieve these results, EPD entered into a contract with LAW Engineering and Environmental Services, Inc. (LAW) to design and construct two 900'-1,000' salt-water monitoring wells in the Upper Floridan aquifer of Brunswick, Georgia, and to continuously monitor water levels and salinity until June 30, 2006. The general objective of the proposed project is to
... provide quarterly electronic reports on the chloride content in these wells to EPD and the United States Geological Survey (USGS).
GENERAL APPROACH

open hole well in two separate permeable zones within the Upper Floridan aquifer. The well was geophysically logged prior to completion. Water level and conductivity measuring instruments that are capable of making digital measurements a minimum of once per hour were installed downhole in each of the two zones. Upon completion and final instrumenting of this well, LAW prepared a draft report describing and illustrating site geologic conditions (including lithologic and geophysical logs), stratigraphic and hydrostratigraphic identifications, "as-built" conditions, instrumentation settings, and preliminary water level and salinity data. After review of this draft report by the EPD, LAW prepared the necessary modifications to submit this final report. In accordance with EPD' s March 12, 2001 revised work plan, monitoring of the upper-water bearing zone will continue until December 31, 2005, and monitoring of the lower water-bearing zone will continue for a minimum of six continuous months after well completion. LAW will submit quarterly reports of water level and salinity data in digital format to EPD and the USGS for the calendar years 2002, 2003, 2004, and 2005. Each report will provide a short narrative description and water level and salinity data in a graphical format.

In accordance with the EPD Scope of Work, this first well (TW34H504/505) was completed before December 31, 2001. Well designation TW34H504 corresponds to the upper permeable zone and TW34H505 corresponds to the lower permeable zone. In this report the designation TW34H504/505 corresponds to the combined well facility constructed at the Southside Baptist Church location.

2.0 DRILLING AND WELL CONSTRUCTION METHODS
Prior to initiating field work, LAW visited the Georgia District of the Water Resources Division of the U.S. Geological Survey (USGS) and the Georgia Geologic Survey (GGS) to review relevant files, data, and publications and to discuss technical matters concerning geology, hydrogeology, well construction and water quality within the Floridan aquifer in the Brunswick area. Following these meetings, LAW discussed drilling strategies with the drilling subcontractor. Based on these meetings, LAW prepared and presented to EPD for approval the project design for well drilling, construction, and instrumentation (Phase 1 of this project).

GEOLOGY The geology, to a depth of 1,000 feet, was studied from publications and unpublished government records to provide site-specific geologic and hydrogeologic interpretation for the Southside Baptist Church site. To accomplish this, LAW obtained lithological and geophysical logs and viewed televiewer recordings of various wells located in the vicinity of the proposed drill site. The location of the first deep monitoring well (TW34H504/505) at the Southside Baptist Church site was confirmed on July 12, 2001, by the GGS.

Southside Baptist Church Drill Site

The lithology encountered at the Southside Baptist Church drill site is summarized in Table 1.

Well 34H504/505 was drilled to a depth of 1,000 feet. The lithologic log is presented in

Appendix A, and the geophysical logs are presented in Appendix B.

The geophysical logs from Well TW34H504/505 exhibit a reasonable correlation with the lithological log from this well. The base of the Miocene and younger formations is noted by a "C-marker" on gamma-ray logs and the base of the Oligocene is marked by the presence of a "Dmarker" on gamma-ray logs (Jones and Maslia, 1994). At Well TW34H504/505, the "C-marker" is present at a depth of 568 feet and also represents the horizon at which the top of the Oligocene Suwannee Limestone is encountered. The Suwannee Limestone extends to a depth of 592 feet, as noted by a "D marker" (Jones and Maslia, 1994). This marker also represents the horizon where the upper Eocene Ocala Limestone is encountered. The Ocala Limestone extends to approximately 921 feet where the middle Eocene Avon Park Formation is encountered.
Using gamma-ray logs, this geologic framework can be correlated to other wells around the Southside Baptist Church drill site. The nearest well to the Southside Baptist Church drill site is Well 34H100, a 786-foot deep well located 400 feet to the southeast of TW34H504/505. Based on the geophysical logs for Well 34H100, the base of the Miocene and younger formations is at a depth of 570 feet and the base of the Oligocene Suwannee Limestone is at a depth of 595 feet in this well.
LOCAL HYDROGEOLOGY In the Brunswick area, the general hydrostratigraphy consists of a surficial aquifer, the Upper and Lower Brunswick aquifers, and the Upper and Lower Floridan aquifers, each separated by distinct semiconfining units (Jones and Maslia, 1994). Since the Miocene and younger formations were cased off in monitoring well TW34H504 and the well did not penetrate to the Lower Floridan aquifer, only the hydrogeology of the Upper Floridan aquifer was studied. The top of the Upper Floridan aquifer coincides with the C-marker at the top of the Oligocene Suwannee Limestone (Clarke and others, 1990), and the base is within the top part of the middle Eocene dolomitic limestone of the Avon Park Formation (Jones and Maslia, 1994).

In the Brunswick area, the Upper Floridan aquifer is confined at the top by Miocene silty clay and dense, phosphatic limestone or dolostone (Clarke and others, 1990) and is confined at the base by dolomitic limestone that occurs between 1,000 and 1,050 feet (Wait and Gregg, 1973). The Upper Floridan aquifer in the Brunswick area consists of an upper and lower water bearing, or permeable, zone (Wait and Gregg, 1973). The two permeable zones are separated by a lowpermeability, semiconfining, upper Eocene dolostone unit that partially restricts flow between the zones (Clarke and others, 1990). The upper zone is recognizable on geophysical logs by a series of " kicks" to the left on spontaneous potential (SP) logs and to the right on resistivity logs and can yield up to 70% of the water to wells that penetrate both zones (Wait and Gregg, 1973). The lower zone, which is typically cavernous (Wait and Gregg, 1973), can be discerned using caliper logs in conjunction with acoustic televiewer logs (Jones, 2001). It may also be possible to discern the lower zone by a similar, yet discrete, series of SP and resistivity " kicks" exhibited in the upper zone. The entire Upper Floridan aquifer at Well 34H337 (located approximately 2,000 feet north of Well TW34H504/505) has an average transmissivity and storativity of 1.4 million gallons per day per foot (gpd/ft) and 0.0005, respectively (Wait and Gregg, 1973).

Southside Baptist Church Drill Site The hydrogeology of the Upper Floridan aquifer encountered at the Southside Baptist Church well site was interpreted from geologic and geophysical data obtained during drilling of the well.

The top of the Oligocene (base of the " C-marker" ) was encountered at approximately 568 feet below ground surface (bgs) and marks the top of the Suwanee Limestone. The Oligocene-Eocene boundary (" D-marker" ) was encountered at 592 feet bgs, and marks the bottom of the Suwanee Limestone and top of the upper Eocene Ocala Limestone. The upper-middle Eocene boundary between the Ocala Limestone and Avon Park Formation was encountered around 920 feet bgs at the contact of limestone and dolostone. The upper Floridan aquifer includes the Suwanee Limestone, Ocala Limestone and Avon Park Formation and extends from 570 feet bgs to below well termination at 1000 feet bgs.

UPPER FLORIDAN SALT-WATER MONITORING WELLS Prior to drilling at the TW34H504/505 location, LAW secured a work area that roughly measured 100 by 150 feet. The site was secured with six-foot high chain link fencing and sanitary facilities were provided. Well construction began on September 19, 2001 and was completed on November 17, 2001.

Drilling Methods and Well Construction To construct the Upper Floridan salt-water monitoring well at the Southside Baptist Church site (TW34H504/505), three casings were set at depths that corresponded to significant geologic horizons. The casings included a 20-inch diameter outer surface casing for upper borehole stability, a 14-inch diameter inner casing installed to 585 feet, and an 8-inch diameter well casing installed to 831 feet. Initially, a 12-inch diameter pilot hole was drilled (using mud rotary methods) into surficial sediments until a suitable geologic horizon upon which to set the 20-inch surface casing was encountered (this horizon is typically encountered at a depth between 60 and 150 feet in the Brunswick area, and was encountered at a depth of 55 feet below ground surface (bgs) at TWH34H504/505). After this horizon was encountered, the pilot hole was reamed out to a 24-inch diameter borehole to this depth using mud rotary drilling techniques. To stabilize the boring, 55 feet of 20-inch surface casing constructed of standard steel was installed within the 24inch boring and grouted along the entire length with Type II neat cement grout (ASTM C 150 Type II). The surface casing was grouted by placing cement directly into the annular space between the borehole wall and the casing, while pumping mud from the bottom of the annular space.
Following installation and grouting of the 20-inch casing, a nominal 19-inch diameter boring was advanced to the top of the Upper Floridan aquifer using mud rotary drilling techniques. Near the completion of the nominal 19-inch diameter borehole, LAW contacted the EPD to provide downhole geophysical logging services of the Miocene deposits. Downhole digital SP, resistivity, gamma, caliper, and temperature logs were collected on September 28, 2001. The logs are presented in Appendix B. Following the geophysical logging, a 14-inch standard steel casing was installed within this borehole to a depth of 585 feet bgs. This depth roughly corresponds to the top of the Ocala Limestone, where the first continuous competent limestone formation was encountered at 592 feet bgs. The annular space around the casing and the borehole wall and the surface casing was cemented its entire length by pressure-grouting Type II neat cement grout through the inside diameter of the 14-inch steel casing.
Next, a 9 -inch diameter pilot boring was advanced into the limestone using reverse air rotary drilling techniques. The nominal 9 -inch diameter boring penetrated the Upper Floridan aquifer and terminated at an approximate depth of 1000 feet at the base of the Upper Floridan aquifer at the Southside Baptist Church drill site. Near the completion of the nominal 9 -inch diameter

borehole, LAW contacted the EPD and the USGS to provide downhole geophysical logging services. Downhole digital SP, resistivity, gamma, caliper, acoustic velocity/porosity and temperature logs were collected by the EPD on October 11, 2001. The logs are presented in Appendix B. LAW, EPD, and the USGS reviewed logging results and participated in selecting the monitoring zones for the upper and the lower permeable zones of the Upper Floridan aquifer at well TW34H504/505.

A 13.5-inch diamter bit was used to ream-out the pilot boring to a depth of 835 feet bgs, which corresponds to the top of the lower permeable zone. Prior to this activity, coarse sand was tremied down the borehole to fill the entire length of the lower permeable zone in order to prevent materials produced from the subsequent drilling and grouting operations from entering the zone. An 8-inch standard steel casing was then installed within the nominal 13.5-inch borehole to a depth of 831 feet bgs, terminating near the top of the lower permeable zone. Centralizers were installed at the following locations above the bottom of the 8-inch casing: 2.5, 21, 38 and 80 feet. The remaining 42-feet long sections of pipe had a half-moon type centralizer welded 4 feet from the top of the section and staggered with respect to each other. The 8-inch casing was pressure grouted from a depth of 841 feet bgs up to 759 feet using Type II neat cement grout. After allowing the grout to harden for four days, the concrete float shoe and cement plug were drilled out using a 7 -inch bit. The sand-filled 9 -inch open hole was then cleaned-out using an air-lift method. This method of completing the monitoring wells was used so the grout seal between the upper and the lower permeable zones was not compromised by subsequent drilling operations. As constructed, the upper monitoring zone designated as TW34H504 extends from 606 to 759 feet bgs, and the lower monitoring zone designated as TW34H505 extends from 841 to 1,000 feet bgs. The static water level at the site is above ground surface; therefore, the well was constructed to allow the temporary " shut-in" of the well during non-drilling times so that the well could not flow. Well completion details are summarized on Figure 2 and on the lithologic log in Appendix A.

LAW oversaw all drilling activities at the drill site. During drilling operations for the well, LAW collected cuttings at a minimum of 10-foot intervals and maintained records of drilling progress and drilling conditions. Cutting samples from the well were collected in two sets and one set was provided to the USGS. The site geologist described the lithology of the cuttings using the Unified Soil Classification and the USGS lithologic classification system. During drilling and

well installation, the site geologist was in continuous communication with both the Project Manager and the Principal Investigator regarding progress of the project.

Well development procedures of the lower zone included air lifting for two hours to remove larger solid material from the test well. Development continued until " clear" water was produced and a water quality parameter (conductivity) stabilized. The upper zone was developed by allowing the well to flow for an 8-hour period until " clear" water was produced and a water quality parameter (conductivity) stabilized. Drilling fluids produced during reverse air rotary drilling and development were treated using a trailer-mounted particulate matter filter system with a 400-gallon per minute capacity. This filter was used in conjunction with baffled settling tanks so that turbid water did not enter any surface water body. This particulate matter filter system was trailer-mounted with two primary filters (100 micron) that could be operated either in parallel or series and a bank of four polishing filters (25 to 50 micron). The water was then conveyed away from the well site so that the water did not damage the site. Piping, hay bales, and silt fencing were used as necessary to accomplish this conveyance.

Well TW34H504/505 was completed at land surface with a four-inch thick concrete pad with dimensions of five feet by five feet. The casing of the well was left at a height of three feet above the pad to accommodate the installation of valves to control artesian flow. The drill site was restored after completion of all drilling operations. Site restoration included removal of all drilling equipment and drilling debris, filling mud sumps and ruts created by drilling equipment, and seeding with a low-maintenance grass. An as-built schematic and photographs of the completed well head are shown in Appendix C.

3.0 SAMPLING METHODS
The well was sampled so that in-situ conductivity measurements could be related to the water samples obtained from the wells. After collection, the water samples from each zone were analyzed by an EPD laboratory for TDS and chlorides. The analyses are included in Appendix E. The well was allowed to free-flow to withdraw water from the test well at each zone to be monitored. As the well flowed, the water quality parameters of pH, temperature, and specific conductivity were measured, and water samples were taken after the parameters stabilized.

4.0 LONG-TERM MONITORING METHODS

August 2002

WATER LEVEL MEASUREMENTS Two Hydrolab Diver water-level loggers were installed to provide measurements of potentiometric head changes in the monitoring well. An accuracy of +/- 0.1 foot can be achieved by the water-level loggers used in the well. The instruments are programmed to record the head once per hour. The water-level loggers were initially installed for the December 2001 monitoring period to depths of 20 feet bgs in both the upper and lower monitoring zones. The logger installed in the upper monitoring zone is currently set at a depth of approximately 10 feet bgs and the logger in the lower monitoring zone is currently set at approximately 7 feet bgs. The dataloggers were reset to the shallower depths to prevent water pressure from exceeding the maximum rated range of the instruments in the event of significant increases in water level. Transducer settings with minimal depth of water cover enabled LAW to select pressure transducers with lower pressure ratings. Since instrument accuracy is a percentage of pressure rating, application of lower pressure on the tranducers enabled LAW to use transducers with increased accuracy for measuring pressure. Information and specifications of the installed instruments are presented in Appendix D.
SALINITY MEASUREMENTS A datalogger/salinity measurement device was installed to monitor salinity in each zone. A Solinst Reelogger with a downhole conductivity probe was installed to monitor the upper zone, while a Hydrolab MiniSonde 4A was installed to monitor the lower zone. The measurement devices operate by measuring conductivity as a surrogate of salinity. Calibration of each device was conducted in accordance to the manufacturers instrument specifications. The instruments were programmed to record a conductivity measurement once per hour. The conductivity measurement devices are set near the mid-depth of the zone to be monitored (670 feet bgs in the upper zone, and 920 feet bgs in the lower zone). The Hydrolab MiniSonde, which has internal datalogging capability, is suspended on a stainless steel cable. The conductivity probe for the Solinst Reelogger monitoring device in the upper zone is raised and lowered through a 1-inch observation riser and screen located in the annulus between the 14-inch open hole and the 8-inch casing. Data from the Hydrolab lower zone measurement system will be downloaded on a monthly basis by lifting the MiniSonde to the surface. Retrieval of the device is accomplished by manually reeling in the stainless steel cable. Once at the surface, the data can be downloaded

from the MiniSonde to a laptop computer. The MiniSonde will be calibrated while at the surface. Data from the Solinst upper zone measurement system will be downloaded on a monthly basis from the surface-mounted Reelogger datalogger unit. The Solinst probe will be lifted to the surface and calibrated and checked each month. Retrieval of the down-hole probe is accomplished by manually reeling in the data transmission cable, which contains an integral safety cable. Information and specifications of the installed instruments are presented in Appendix D.

5.0 REPORTING TO EPD
In accordance with the March 12, 2001 Scope of Work issued by the Georgia EPD, LAW is contracted to monitor the upper water-bearing zone (TW34H504) until December 31, 2005, and monitor the lower water-bearing zone (TW34H505) for a minimum of six continuous months after well completion, or as directed by EPD. LAW will submit quarterly reports of water level and salinity data to EPD and the USGS, via e-mail, for the calendar years 2002, 2003, 2004, and 2005. Each report will provide a short narrative description and water level and salinity data in both a tabular and graphical format. The yearly reports shall be provided no later than 15 days after the end of each quarter, which shall be March 31, June 30, September 30, and December 31 of each year.

This site report also includes monitoring results for 2001, which are presented in Appendix E. These results include water level monitoring data from the Hydrolab Divers, suspended in the annular space between the 14-inch and 8-inch casings (upper zone) and inside the 8-inch casing (lower zone), conductivity data from the Solinst Reelogger conductivity probe suspended at 670 feet bgs at the midpoint of the upper monitoring zone and from the Hydrolab MiniSonde suspended at 920 feet bgs at the mid-point of the lower zone, and barometric pressure data from the Hydrolab Diver installed inside the protective well house. The data series for the Hydrolab MiniSonde was terminated prematurely after approximately three days of measurement due to a low battery condition in the MiniSonde. The Minisonde was returned to Hydrolab for repairs, where a failure of the internal battery was discovered. The MiniSonde has been repaired by Hydrolab and is now operating properly.

The Diver and the CTD-Divereach have a 22mm diameter and can be completely installed within a one-inch borehole. The CTD-Diver is 260 mm in length; the Diver is only 125 mm, making it the smallest instrument in the world for automatic measurement and logging of ground water level and temperature.

For long-term reliability,both instruments are completely sealed within a stainless steel (AISI 316-L) housing, making them insensitive to moisture or external electrical or chemical influences. Once installed, the instruments automatically monitor parameters and register these data in the internal memory. The Diver can store 24,000 readings. Over a six-month period, you can execute and store a measurement every ten minutes before memory is full. The CTD-Diverhas a memory capacity for measuring three parameters 16,000 times. The built-in battery has a lifespan of eight to ten years.
The specially designed BaroDiver eliminates the need for vented cables. The BaroDiver records atmospheric pressure data, and EnviroMon software automatically calculates adjusted level.

Both the Diver and the CTD-Diver are accurate to 0.1% FS for depth and 0.1 degree C for temperature. The CTD-Diver's conductivity sensor is accurate to 1%FS. It can display either conductivity or specific conductance. The fourelectrode conductivity sensor provides accurate, reliable measurements over longer periods of time and requires no special maintenance, only routine cleaning after each monitoring session.
Because of their design, the Diver and the CTD-Diverare virtuallv maintenance-free. Thev are easv to install inside a borehole, suspended from a wire. Additionally,these devices can be programmed in seconds, either in the field or in the office, with EnviroMon software. Relevant data can be entered, the sample rate adjusted freely, and readings taken at any time via the optical readout unit that connects the instrument to any portable computer. The data can be presented both graphically and in the form of charts. It is also possible to convert the data directly to spreadsheet files for further processing.

The EnviroMon software (Windows 95/NT compatible) nialces the system complete. It programs your instrument (direct or future start option), processes the data recorded and can export it to other formats. The EnviroMon software also includes the Barometric Compensation Wizard, which automatically compensates for the measured variations in atmospheric pressure. For the CTD-Diver, the Calibration Wizard is also available allowing for easy recalibration of the conductivity sensor.

Model 2001 Reelogger

The Reelogge* i s a water level andlor multiparameter datalogging svstem* that introduces many new concepts ideal for field use by hydrogeologists, hydrologists and anyone wishing t o monitor water automatically.
Inexpensivecoaxial cable can be used for dedicated units, as the system only requires 2-conductor cable and uses a barometric sensor at surface. Portable reel units may be fitted with Solinst flat tape, permanently marked each 11100ft. or millimeter. The logger may be housed within a protective well cap, i n an adjacent housing, or within a portable reel. A manual water level dip meter may also be incorporated into the system, making it easy to determine the accurate depth of static water. Reeloggers have a very small but powerful datalogger which operates on a standard 9V battery, and can store up to 100,000 readings i n nonvolatile memory.
An LCD display with three control buttons allows on-site viewing of data and simple programming without any additional equipment. Infra-red communication allows downloading and programming with a lap-top computer without use of cables. For use with computers that do not have a built-in infra-red port, an infra-red adaptor cable is available.
The Reelogger software is very comprehensive and simple to operate on Windows 3.1, Windows95, Windows98 or WindowsNT. Extensivegraphing capabilities are built into the software. The software also provides automatic compensationfor barometric pressure variations.

Interchangeable Probes

Water Level Sensor

The modular system can operate up to 8 separate sensors, allowing the user a choice of which to purchaseor use. At time of printing, pressurellevel, conductivity and pH sensors are available, with more to follow shortly. All are temperature compensatedand the temperature readings from the first probe i n line are also recorded. The pressurellevel measurements are compensated for barometric pressure using a barometric sensor in the logger unit itself. This eliminates the need for vented cable.
The narrow diameter sensors are all smart sensors. They have a chip inside the probe with the calibration constants and software to activate and read the sensor for uploading to the logger.
There are threaded connectors at each end to permit in-line connection, ideal for use in narrow diameter wells. For use i n open bodies of water the probes can be attached to a ring connector. Sensors are rugged, highly accurate and reliable over extended periods of time.
When only a single sensor is used, the available memory for data storage is greater than when multiple sensors are used.
Sensors

Water Pressure Probe

Simple water level sensor Pressure (water level) with temperature Conductivity with temperature pH with reference cell and temperature Any combination of the above Additional sensors are plannedfor the near future and can be added without changing the logger software. All specifications are summarized in a table at the back of the data sheet.
Simple Water Level Sensor
A simple water level sensor may also be located within the sensor string. It is pennanetly attachedto the cable, as the first sensor in line. If this sensor and the flat-tape cable options have been chosen, the initial water level reading for calibration purposes is greatly simplified. When the Reelogger is used in a narrow diameter borehole, this water level sensor allows the user to determinewhen the water displaced by the sensors has returned to its natural level. Initial calibration readings may also be taken manually.
Water Pressure Probe
The Solinst pressure sensor uses vibrating wire technology, as i t is very accurate, rugged and stable. The water level data is presented directly, either i n feet to 11100ft, or in metric to 0.25 cm. To compensate the water pressure measurementsfor atmospheric pressure, a temperature corrected pressure sensor is located in the hub of the Reelogger or logger housing, at the surface. This configuration avoids the usual requirementfor vented cables, which are expensive, prone to damage, and may i n some instances give erroneous results due to lag times in pressure equalization. It makes the Reelogger much easier to transport and use.
Conductivity Probe
The Solinst conductivity cell is a new highly accurate, very stable cell which uses advanced electronics to give linear output over a very large range. It auto-adjusts to 10 ranges.
Temperature Sensors

Reelogger, Water Level Sensors, Conductivity Sensors, pH Sensors
. *.
The temperature readingdisplayed by the logger is the temperature output from the first probe in line. Each sensor has its own temperature measuring device fitted within it for calibration purposes. For applications that require critically high accuracy of temperature measurements, which will be stable over long periods of time, a probe with a platinum resistance temperature device (RTD cell) will be available shortly.

Cablerrape

The Reelogger system is digital, therefore twoconductor cable is
- standard. This allows the accurately marked Solinst flat-tape cable
to be used. enablino the user to accuratelv determine the depth of the probe(s) i n the well for calibration and accuracy checks i n the field. This makes it ideal for portable reel mounted units t o be used on shorter term monitoring applications.
The flat-tape cable is permanently marked each 11100 ft. o r each millimeter. Stranded stainless steel conductors resist corrosion, provide strength and are non-stretch for accuracy.
Dedicatedinstallations up to 1000 ft. (3001x1) may use low cost coaxial cable with stranded stainless steel conductors. Lengths up to 3000 ft. (900 m) can be accommodated by the logger power supply, using a low resistance coaxial cable. Each coaxial cable has one marking, at the requested length, and optional marking each 5 ft. or one meter are available.
Note: The pH sensor operates up to a depth limit of 300 ft. (100 m) below water.

Batteries

Only one standard 9 volt alkaline battery is required t o power all the probes and the Reelogger. The battery power available i s displayed on the LCD screen. A convenient battery drawer i n t h e reel version has a second battery in sequence, so that the batteries can be changed one at a time without loss of logging power.
The expected battery life is approximately 100,000 probe log readings. i.e. If one probe is logged every 5 minutes, the batteries would last for one year. When 2 probes are being logged, the memory does not reduce by half, as the date and temperature are only recorded once for any number of probes. If the batteries do run down, the logger will stop recording, but the readings will not be lost.
A separate 15 year battery is used for the internal clock.
