Sources for this information include the many governmental agencies involved in water resources management in the metro Atlanta region. Federal agencies including the Corps of Engineers, U.S. Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA) provided hydrologic and meteorological data. The Georgia Environmental Protection Division (GA EPD) provided water withdrawal data, wastewater return data, sanitary sewer overflow data, as well as detailed water quality information for the region's streams. 1.1: Area Description The Metropolitan North Georgia Water Planning District (Metro Water District) was created by the Georgia General Assembly in 2001 (O.C.G.A 12-5-572) to serve as the water planning organization for the greater metropolitan Atlanta area. The Metro Water District includes 15 counties (Bartow, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Paulding, and Rockdale counties) as well as 91 municipalities partially or fully within these counties (Figure 1-1). The Metro Water District also has seven authorities which provide water, sewer and/or stormwater services. The Metro Water District's plans and policies work to protect water resources in the Chattahoochee, Coosa, Flint, Ocmulgee, Oconee, and Tallapoosa River Basins. 1 Metropolitan North Georgia Water Planning District Water Metrics Report Figure 1-1.

Since the recession began more than two years ago, the region has experienced the slowest population growth period since the 1950s. The region's economic climate is similar to the other metropolitan areas in the nation anemic job growth and heavy losses in a few key sectors like manufacturing and construction. The Atlanta region ranks third, behind Detroit and Phoenix, in the percentage of jobs lost from August 2007 to August 2009. Fulton and Gwinnett counties accounted for more 2 Metropolitan North Georgia Water Planning District Water Metrics Report than half of all the jobs losses in the region. Office vacancy rates increased during the 2001-2002 recession and never returned to pre-recession levels. By the end of 2009, office vacancy levels had reached approximately 17%. As a result, construction activity of retail buildings and housing units in the region has decreased significantly since 2006. Despite the recessions, the Atlanta region still experienced significant population growth of approximately 1 million people during the past decade. Figure 1-2 illustrates the trends in the 15-county regional population, employment, and sales tax revenue over the past decade. Figure 1-2. Regional Population, Employment, and Sales Tax Revenue Trends for the Metro Water District from 2000 2009 Population / Employment (in millions) Metro Water District Total Sales Tax Revenues (in millions) 5.5 5.0 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0.0 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 Total County Sales Tax Revenues Total Regional Population Average Annual Employment Sources: Atlanta Regional Commission, GA Department of Revenue, Bureau of Labor Statistics, and Bureau of Economic Analysis (BEA) $1,000 $900 $800 $700 $600 $500 $400 $300 $200 $100 $- While the recession has taken its toll on metro Atlanta's economy recently, regional forecasters agree that metro Atlanta is poised to add significant numbers of people and jobs over the next 25 years. Forecasters expect the region to grow in population by 2.4 million people and the number of jobs to increase by almost 1.9 million by 2035. 3 Metropolitan North Georgia Water Planning District Water Metrics Report 1.3: Topography, Major Rivers and Streams The Metro Water District occupies a part of the Piedmont Plateau, an upland area with rolling terrain. The upland average altitude is about 1,000 feet above sea level. In localized areas the surface is rugged and extremely hilly. Figure 1-3 illustrates the major river basins and streams in the Metro Water District. The Metro Water District includes parts of six of the fourteen major river basins in the state of Georgia: the Coosa, Chattahoochee, Flint, Ocmulgee, Oconee, and Tallapoosa River Basins. Eleven out of the fifteen counties represented in the District lie within more than one river basin; there are two counties that lie within three river basins and one county that covers four river basins. In order to supply water to their customers, most utilities must move water between river basins. The Metro Water District is located on the eastern sub-continental divide. Downtown Peachtree Street follows the hydrologic ridgeline of the major drainage basins. This ridgeline separates the Gulf of Mexico watershed from the Atlantic Ocean watershed. The Chattahoochee, Coosa, and Flint River Basins (Chattahoochee, Etowah, and Flint Rivers) drain to the Gulf of Mexico; the Oconee and Ocmulgee River Basins (Apalachee, Alcovy, Yellow, and South Rivers) drain to the Atlantic Ocean. The headwaters of both the Chattahoochee and Etowah Rivers are located in North Georgia. These rivers have much larger watersheds than other streams within the Metro Water District, and consequently have larger flows. Both rivers have been dammed by the Corps of Engineers creating two large reservoirs within the District: Lake Lanier on the Chattahoochee River, and Allatoona Lake on the Etowah River. The Chattahoochee has the largest watershed area and highest flows in the Metro Water District. Since 1957 its flow has been controlled by Buford Dam, which controls the 1,040 square miles of the drainage basin above the dam. About 400 square miles of drainage area is uncontrolled between Buford Dam and the point just above Peachtree Creek, which can experience flooding during significant storm events. The headwaters of the South River are near the State Capitol; the Flint River near Hartsfield-Jackson Atlanta International Airport; the Yellow River north of Lawrenceville; and the Alcovy and Apalachee Rivers east of Lawrenceville. 4 Metropolitan North Georgia Water Planning District Water Metrics Report Figure 1-3.

The crystalline rock is not porous so groundwater is only found in isolated fractures and crevices in the bedrock. Deep wells drilled into the crystalline rock may produce enough water to supply a residence or small community, but cannot reliably provide yields large enough for major water systems. As a result, groundwater sources make up less than one percent of the total water available water supply in the Metro Water District. Figure 1-4 illustrates the groundwater level trends at Fort McPherson from 2000 2009. Figure 1-4. Groundwater Levels at Fort McPherson, Fulton County (2000-2009) Depth to Water Level (feet below land surface) 2000 2001 2002 2003 2004 2005 2006 0 2 4 6 8 10 12 14 *USGS Groundwater Monitoring Station Site Name: 10DD02 2007 2008 2009 2010 1.5: Climate and Recent Conditions The climate of the Metro Water District is humid and continental. The winters are mild with very changeable temperatures. According to the National Oceanic and Atmospheric Administration (NOAA), the 30-year normal (average of years 1971-2000) maximum and minimum January temperatures for Atlanta are 51.9F and 33.5F, respectively. The 30-year normal maximum and minimum July temperatures are 89.4F and 70.6F, respectively. The average annual precipitation for the past 80 years, as determined by NOAA, is approximately 48.83 inches. NOAA also describes precipitation using a 30-year normal annual average of 50.20 inches which represents the average annual precipitation from years 1971 2000. This "normal" precipitation average includes a wet period and does not represent Atlanta's true long-term average annual precipitation levels. Using the 6 Metropolitan North Georgia Water Planning District Water Metrics Report long-term precipitation average of 80 years gives a better depiction of the average conditions of this region. Some of the most extreme drought conditions occurred during 1954 with 31.80 inches of precipitation as well as in 2007 with 31.85 inches. Flood conditions occurred in 1948 when the region received 71.45 inches of rain as well as in 2009 with 69.43 inches of rainfall. Normal (average of years 1971-2000) monthly rainfall ranges from 3.11 inches in October to 5.38 inches in March. Dry periods occur mainly during late summer and early autumn, with maximum thunderstorm activity during July. The average annual snowfall is 2.4 inches. Precipitation occurs an average of 116 days each year. Relative humidity averages 68%. Weather conditions during 2000 2009 varied from record breaking heat and drought conditions in 2007 and 2008 to record breaking floods in 2009. Figure 1-5 compares the 2000 2009 average annual precipitation to the normal and long-term average annual precipitation. Figure 1-6 shows the number of days each year that the temperature was greater than or equal to 90 F and the total annual precipitation for 2000 2009. 7 Metropolitan North Georgia Water Planning District Water Metrics Report Figure 1-5.

There are however, manmade ponds, lakes and reservoirs. The purpose of reservoirs is to store water during wet periods for use during times of drought as well as for flood control. The two largest impoundments were constructed by the U.S. Army Corps of Engineers and are keystones in the District's water resource system. Lake Lanier is located in the northeast corner of the District and Allatoona Lake is in the northwest corner. Lake Lanier is the largest and furthest north of a series of Corps of Engineers reservoirs on the Apalachicola-Chattahoochee-Flint (ACF) River System. Allatoona Lake is a reservoir located on the Etowah River in the upper reaches of the Alabama-CoosaTallapoosa River System. Figures 2-5 and 2-6 illustrate the changes in the levels of Lakes Lanier and Allatoona during the period of 2000 2009. In 2007 the level of Lake Lanier began to drop in response to drought conditions. Lake Lanier reached a low elevation of 1050.8 feet on December 26, 2007, which was 14.2 feet below the average winter level of 1065 feet. By 2008, lake levels were averaging 15 feet below normal levels on a monthly basis. The flood in September 2009 brought Lake Lanier back to normal pool elevation. Similarly, Allatoona Lake experienced lower levels in 2007 and 2008 due to the drought. Allatoona Lake reached a low elevation of 818.9 feet on December 14, 2007 which was 6.1 feet below the average winter level of 825 feet. 13 Average Daily Elevation (ft) Metropolitan North Georgia Water Planning District Water Metrics Report Figure 2-5.

The counties within the Metro Water District withdraw drinking water from the Chattahoochee, Coosa, Flint, Ocmulgee, Oconee, and Tallapoosa river basins. The vast majority of the water supply for the Metro Water District, over 99%, is from these surface water sources. Groundwater sources make up less than one percent of the total available water supply in the Metro Water District due to geologic conditions. Groundwater supplies several small towns and is used as a supplemental source. Table 3-1 summarizes the total average annual daily raw water demand in the Metro Water District for the period 2000 2009. This includes water withdrawn from surface and groundwater sources, including public and industrial water supplies but does not include water withdrawals by power plants. This table also includes water purchased from outside the District area and subtracts water sold to communities outside the District area. Table 3-2 summarizes the average annual daily water withdrawals by surface water intake. Unless otherwise noted, all withdrawal data represents raw water withdrawn from rivers and reservoirs to be treated and sent to customers. Table 3-3 summarizes the groundwater sources utilized for public and industrial water supply within the Metro Water District. Table 3-4 and Figure 3-1 represent the average annual daily surface water withdrawal by the Chattahoochee, Coosa, Flint, and Ocmulgee basins from 2000 2009. 3.2 Impacts of Weather Variability Year-to-year precipitation levels are extremely variable in Georgia. The region witnessed both droughts and floods within the past decade. The region received above normal rainfall in years 2003 through 2005. Hurricanes Frances, Ivan, and Jeanne in September of 2004 as well as Hurricanes Dennis, Cindy, and Katrina in July and August of 2005 were the cause of high levels of precipitation. Prolonged rainfall in the summer and fall of 2009 led to record-breaking flood conditions throughout Metro Atlanta. Water demand typically decreases during periods of heavy rainfall. Two droughts in the decade brought about the adoption of drought restrictions which also served to reduce water demand. In 2001, the region suffered from drought conditions combined with the effects of a national recession. Again in 2007, the region began experiencing record-breaking drought conditions and an economic recession. In response to the diminishing water supply, GA EPD issued a series of drought response 17 Metropolitan North Georgia Water Planning District Water Metrics Report procedures. The following list summarizes the drought restrictions enacted from 2000 2009: April 2000: Voluntary watering reductions requested. June 2000: Watering restrictions imposed statewide no outdoor water use from 10 a.m. until 10 p.m. daily. August 2000: Restrictions relaxed outside of metro Atlanta (remain in place for metro Atlanta). August 2001: Restrictions lifted. May 2004: Voluntary non-drought schedule limits outdoor water use to Odd-Even watering schedule: Tuesdays, Thursdays, and Sundays for odd-numbered addresses and Mondays, Wednesdays, and Saturdays for even-numbered addresses. June 2005: Mandatory non-drought schedule requires outdoor water use only on days listed for odd- and even-numbered addresses. June 2006: Level 1 drought schedule limits outdoor water use to Odd-Even watering schedule within the hours of 12:00 midnight to 10:00 a.m. and 4:00 p.m. to 12:00 midnight. April 2007: Level 2 drought schedule limits outdoor water use to Odd-Even watering schedule within the hours of 12:00 midnight to 10:00 a.m. The washing of hard surfaces (streets, gutters, sidewalks, etc) is prohibited except for public health and safety. September 2007: Level 4 drought schedule for 61 north GA counties prohibits all outdoor water use. The remainder of the state placed under level 2 drought schedule. Governor enacts 10% Reduction mandate. May 2008: Level 4 drought schedule continues for 55 north GA counties prohibiting all outdoor water use; 60 middle GA counties under level 2 drought schedule; 44 south GA counties under level 1 drought schedule June 2009: Non-drought schedule statewide limits outdoor water use to Odd-Even watering schedule. Transitioning into 2008, water use decreased significantly as drought conditions continued and the nation fell into another, more significant recession. During this time, water utilities experienced water use reductions ranging from 10% to 25%. In addition, water utilities experienced revenue reductions ranging from 4% to 23%. The recession also had a marked effect on water use as population growth slowed and employment numbers decreased. The 10% reduction mandate enacted in September 2007 was removed in April 2008 and the Level 4 Drought Response (May 2008) was removed in 18 Metropolitan North Georgia Water Planning District Water Metrics Report June 2009. However, with the flood in 2009, water use continued to decrease, the recession continued and a non-drought water restriction schedule remained in place. Table 3-1.

Per capita water use in this report is defined as the total annual volume of water demand divided by the population served within the service area. Any water purchased from outside the distribution area is included, while the water sold outside the distribution area is subtracted. The per capita use metric has limitations and caution should be used when comparing water systems with different socio-economic characteristics and those with different climates. There are a number of variables that cause legitimate differences in per capita use among communities. Even when reviewing per capita water use changes within one water system, care should be taken to understand temporary fluctuations due to weather, drought restrictions and economic recession. Reasons for differences in per capita use include: Climate Outdoor water use increases in areas with hot summers and lower rainfall. Rainfall events and the distribution of rainfall also influence use. Commercial and Industrial Activity: Type and Density Areas with a larger employment base and workers commuting into the service area will have higher per capita rates as will areas with many hotels and a large visitor population. Dense commercial areas have less landscaped areas using less outdoor irrigation. Manufacturing typically uses more water than offices. Suburban and exurban areas with little commercial or industrial activity will have lower per capita water use. Housing: Type and Density Water use is typically higher in single family housing than in multi-family. Areas with multi-family housing use less water per person because of fewer bathrooms, common or off-site laundries, and less landscaping per unit. Higher densities reduce landscaped areas that use supplemental irrigation. Single family houses on small lots use less water than larger lots. Similarly, income has an effect on water use as it relates to housing characteristics. Water Conservation and Drought Restrictions Water conservation and efficiency measures reduce water use over the long term, while drought restrictions create temporary reductions in water use. Other factors that influence water use include the age of structures, income level and the total cost of water and sewer services. 23 Metropolitan North Georgia Water Planning District Water Metrics Report Table 3-5 includes the per capita water use from 2000 through 2009 for each county within the Metro Water District. It does appear that for the region as a whole the per capita use rate is trending down. However, the dramatic reductions in 2007, 2008 and 2009 are primarily due to the outdoor water restrictions put in place during the drought, the economic recession and the wet weather in 2009.

Data Sources Surface Water Withdrawal Data, 2000-2001: ARC calculations from EPD Daily Surface Water Withdrawal records; 2002-2009: EPD Monthly Surface Water Withdrawals electronic database County population estimates, 2000-2008: Regional Economic Information System, Bureau of Economic Analysis (BEA), U.S. Department of Commerce Table CA1-3 (http://www.bea.gov/regional/reis/); 2009: U.S. Census Bureau. Population estimates for Fulton, DeKalb, and Clayton counties were calculated by multiplying BEA county population estimates by the ARC SuperDistrict or Census Tract's proportion in the ARC county totals. The BEA released revisions for 1967 - 2007 on April 22, 2010. Population was revised back to the year 2000. 24 Metropolitan North Georgia Water Planning District Water Metrics Report 3.4 Single Family Residential Water Use Single family residential customers represent a relatively uniform group of water users. A single family account typically includes one dwelling connected to city water supply through a single water meter. For those lots which do not account for irrigation use with a single meter, an additional meter is designated for irrigation. This differs from multifamily residential accounts which include multifamily dwellings serviced by larger meters. Nonresidential water accounts include commercial and/or industrial customers. Table 3-6 summarizes available single family residential water use data within the Metro Water District from 2007 - 2009. The data provided by local water systems only represents single family households; while the majority of utilities distinguish between residential and commercial accounts, not all utilities track single family residential use. Care should be taken when comparing single family residential per capita use as population density, water rates, and category definitions vary by county and utility. Water use includes irrigation. The effect of the water outdoor watering ban enacted in 2008 and the wet weather in 2009 is evidenced by the decrease in water use. 25 Metropolitan North Georgia Water Planning District Water Metrics Report Table 3-6.

Approximately 99% of treated capacity is publicly-owned. The remaining treatment capacity is permitted to privately-owned and operated facilities including those owned by public school systems, industries, campgrounds, mobile home parks and residential developments. Reported here are the 2009 permitted capacities and average wastewater returns of the publicly-owned facilities available from GA EPD. These facilities are referred to by several different names including: water pollution control plants (WPCP), water reclamation facilities (WRF), wastewater treatment plants (WWTP), and publicly-owned treatment works (POTW). Sixty-seven percent (67%) of the existing publicly-owned permitted capacity in the Metro Water District is located in the Chattahoochee Basin, including the five largest wastewater facilities. Wastewater treatment facilities are permitted on a maximum monthly average on a daily basis and a maximum weekly average on an average daily basis. Many land application facilities (LAS) or decentralized systems do not have permitted flow limits. Tables 4-1 through 4-4 summarize wastewater capacity versus peak discharge in 2009 for the Chattahoochee, Coosa, Flint, and Ocmulgee river basins. Tables 4-5 through 4-8 summarize average wastewater returns for the Chattahoochee, Coosa, Flint, and Ocmulgee from 2000 to 2009. 27 Metropolitan North Georgia Water Planning District Water Metrics Report Table 4-1.

SSOs typically occur in urbanized areas where wastewater from households and businesses is conveyed to treatment plants via a separate sanitary sewer system. There are a number of causes for an SSO, most common of which is a blockage in the system. Blockages can be due to grease, household trash and debris, construction material, or roots and other natural materials. SSOs can also occur due to increased infiltration/inflow (I/I) during storm events or periods of sustained rain. This unauthorized/unintended I/I results in increased flow that exceeds the design capacity of the sewer system, causing overflow into streets and streams. The system itself can be the cause whether it is a break or collapse of pipes, a power outage, malfunction at the pump station, or operator error. Pipes can be damaged by storms, erosion at stream crossings, or by contractors and developers who are unaware of the sewer system location. A total of 11,330 SSOs were reported to GA EPD in the Metro Water District from 2000 2009. Figure 4-2 summarizes the total annual number of SSOs occurring in the District from 2000 2009. Of the total SSOs reported in the 2000-2009 period, 11,145 had known volumes. GA EPD defines a "major" spill as any discharge of raw sewage that exceeds 10,000 gallons. Approximately 90% of the SSOs in 2000-2009 with known volumes were less than 10,000 gallons and approximately 1.3% of SSOs were greater than 1 million gallons. A total of 8,341 SSOs had identified causes (causes were only available for 2002-2009). Figure 4-3 illustrates the percentage of SSOs attributed to various causes. Pipe blockages accounted for approximately 73% of all SSOs from 2002 2009; more specifically, accumulation of grease accounted for 47% of SSOs, general back-ups due to household trash and debris accounted for 19%, and roots and other natural debris accounted for 7% of SSOs. Rain accounted for 9% of all SSOs in the Metro Water District from 2002 2009. The majority of rain induced SSOs occurred as a result of Hurricanes Dennis, Cindy, and Katrina in July and August 2005 and the September floods in 2009. Only 1% of rain induced SSOs occurred during 2007 and 2008 which is evidence of the drought. 36 Number of Sanitary Sewer Overflows Metropolitan North Georgia Water Planning District Water Metrics Report Figure 4-2.

The standards are based on the designated use of the water body and reflect water quality goals established by the Clean Water Act in 1972. Section 303(d) of the Clean Water Act requires that all states list water bodies that do not meet water quality standards. The GA EPD publishes a bi-annual list of streams that do not meet State water quality standards, referred to as the 303(d) list. Table 4-11 summarizes the 2008 303(d) list showing the total stream miles in the District that are supporting or not supporting the designated use, and those where the assessment is pending. Those streams listed as `supporting' represent streams whose water quality supports its designated uses ; `non supporting' streams are those that do not meet water quality standards and therefore do not support its designated uses. When available data were insufficient to assess if the waters supported or did not support, the water were placed in the "Assessment Pending" category. Table 4-12 lists the total number of stream miles according to the different criteria violations; streams can be in violation of multiple criteria. Since 2000, the total number of stream miles in Georgia that do not support the designated use has increased. A similar increase has been experienced for the streams monitored in the District. This increase does not necessarily reflect worsening water quality or show that the Watershed Management Plans developed by the Metro Water District have not been effective for a number of reasons: (1) The increase in number of impaired streams is due in part to an almost 20% increase in miles of stream monitored; (2) Water bodies remain on the 303(d)/305(b) list until an active delisting procedure is undertaken; (3) Over 50% of the listed streams are for fecal coliform which is a parameter which may not meet state water quality standards due to natural background sources. This standard also does not accurately reflect the potential for human illness based on contact with surface water. Figure 4-4 illustrates the impaired streams located within the Metro Water District including those with fecal coliform violations. Conversely, figure 4-5 illustrates the impaired streams located within the Metro Water District not including the streams with fecal coliform violations. 38 Metropolitan North Georgia Water Planning District Water Metrics Report Figure 4-4.

The broad categories of pollutants/indicators that affect the standards are: organic matter, nutrients, bacteria, suspended solids, and toxics. Water quality standards and discharge permits are written to control the effects of these water quality indicators. Such effects include depletion of dissolved oxygen, excessive plant growth, transmission of diseases, and reduction of biological communities (fish and wildlife). These water quality indicators can originate from "point source" discharges (wastewater treatment plants) or from "nonpoint sources" such as urban stormwater runoff and sewer overflows. Organic Matter Organic matter, in and of itself is not a pollutant and naturally occurs in even the most pristine waters. Organic matter decomposes upon entering a stream, using dissolved oxygen present in the water to break down the organics. Naturally occurring 40 Metropolitan North Georgia Water Planning District Water Metrics Report microorganisms consume the dissolved oxygen in the water during the oxidation of the organic matter. Streams are monitored for biochemical oxygen demand (BOD) which is the amount of dissolved oxygen needed by the aquatic microorganisms to oxidize the organic matter. Water quality issues (primarily low dissolved oxygen) arise when the amount of organic matter exceeds the assimilative capacity of the stream and dissolved oxygen standards are compromised. Specifically, BOD-5 is measured, representing the amount of oxygen used in 5 days to decay organic matter. Wastewater effluent typically has a BOD-5 permitted level of 30 mg/L. Nutrients In the context of this report, nutrients refer to phosphorus and nitrogen because they are essential in the growth of algae and other aquatic plants. Like organic matter, nutrients occur naturally in streams; however, large amounts of nutrients can contribute to excessive plant growth in downstream reaches. Excessive algae and aquatic plants result in high dissolved oxygen concentrations during the day (photosynthesis) and a depletion of dissolved oxygen at night (respiration). High levels of phosphorus and nitrogen can be contributed by wastewater discharges and stormwater runoff (i.e. organic matter, fertilizers, animal waste, etc.). The nutrient water quality standards include annual phosphorus loading for major lake tributaries and nitrogen concentrations at select locations in major lakes. Total phosphorus (P) includes organic phosphorus and orthophosphate (PO4) and is measured to evaluate overall phosphorus loading trends. Total nitrogen is the summation of the total kjeldahl nitrogen (TKN) and nitrite/nitrate concentrations, while TKN represents the organic nitrogen and ammonia in a sample. Neither TKN nor total nitrogen was available for stream gages along the South and Flint Rivers. The phosphorus, ammonia and total nitrogen concentrations indicate that the wastewater treatment facilities have significantly increased the level of treatment. Total Suspended Solids The primary sources of suspended solids in the rivers and lakes are stormwater runoff and stream bank erosion. Wastewater discharge and excessive algal growth are also sources of suspended solids. Suspended solids include organic particles such as plant fragments, animal wastes, organisms, and soil. Depending on the size of the particles and the movement of the stream, the solids may remain in suspension or settle to the streambed. Suspended solids become a water quality concern when they cause the water to become unnaturally cloudy or they adversely affect the aquatic organism habitat. Turbidity is a measurement of the amount of transparency lost in the water due to suspended solids. According to GA EPD, clear streams will have a turbidity reading of approximately 10 Nephelometric Turbidity Units (NTU) whereas a cloudy stream will have a turbidity reading of approximately 50 NTU; a very cloudy or muddy stream will 41 Metropolitan North Georgia Water Planning District Water Metrics Report have a turbidity reading of 100 to 500 NTU. There are currently no standards set for turbidity. The Georgia criterion for all waters is "All waters shall be free from turbidity which results in a substantial visual contrast in a water body due to man-made activity." Bacteria The presence of potentially harmful bacteria in a water body is generally linked to the amount of human and animal waste material concentrated in the water. High levels of fecal coliform bacteria are contributed by stormwater runoff (wildlife and pet waste), failing septic systems, sewer overflows and to a lesser extent, treated wastewater discharge. The presence and propagation of bacteria and viruses can be an important public health concern and necessitate the restriction of direct human contact with affected waters. Fecal coliform bacteria levels are monitored to indicate the potential presence of other harmful bacteria and viruses. The GA EPD water quality standard for fecal coliform levels varies according to the designated use of the water body. In general, for waters designated for contact due to recreational use, the fecal coliform limit is 200 CFU/100 mL from May until October, when recreational activities are expected to occur. From November until April, fecal coliform levels range from 200 to 4000 CFU/100 mL depending on the designated use. Toxics Toxics are chemicals, elements, and compounds which generally do not occur naturally in stream environments, and which pose a serious health threat to plants, animals or humans that come in contact with the water. Common toxics include pesticides, herbicides, heavy metals, and solvents. Toxics in river systems are generally associated with industry or runoff from urban areas. There is very little heavy industry in the Atlanta area and the presence of toxic pollutants in the Region's streams has not been documented as a problem. 42 Metropolitan North Georgia Water Planning District Water Metrics Report 4.4.3 Chattahoochee River Water Quality Trends Figures 4-6 through 4-11 illustrate water quality trends for BOD-5, phosphorus, ammonia as nitrogen, total nitrogen, turbidity and fecal coliform near Fairburn (USGS Gage No. 02337170) along the Chattahoochee River from 1972 until 2009.

Georgia Department of Natural Resources Environmental Protection Division. 55 Metropolitan North Georgia Water Planning District Water Metrics Report [This page intentionally left blank] Metropolitan North Georgia Water Planning District Water Metrics Report Appendix: Water Withdrawal Data by County The following tables summarize the water supply and sales for each county from 2000 2009. Water supply includes the average annual raw water withdrawal from each source as well as the average annual amount of water purchased from outside sources. Average annual water sales are provided for water sales outside the county limits. These tables also indicate the peak daily withdrawal. Seasonal water use typically rises during the spring and summer months as outdoor water use increases. Winter water use typically describes a "baseload" condition, since most of the use occurs indoors and varies little from week to week. However, extreme cold conditions will produce dramatic increases in use when faucets are left dripping to prevent freezing pipes.
