Abstract

The U.S. Geological Survey (USGS) has been working 

with the Albany Water, Gas, and Light Commission to monitor 

ground-water quality and availability since 1977. This report 

presents the findings for July 2005 through June 2006 and 

summarizes the ground-water and surface-water conditions for 

2005. Water levels in 14 wells were continuously monitored in 

Dougherty County, Georgia. Water levels in 12 of those wells 

were above normal, one was normal, and one was below normal. Ground-water samples collected from the Upper Floridan 

aquifer indicate that nitrate levels have increased in 13 wells 

and decreased in two wells from a year earlier. A sample also 

was collected from the Flint River. A trilinear diagram showing 

the percent composition of selected major cations and anions 

indicates that the ground-water quality of the Upper Floridan 

aquifer at the Albany wellfield is distinctly different from the 

water quality of the Flint River. To improve the understanding 

of the ground-water flow system and nitrate movement in the 

Upper Floridan aquifer, the USGS is developing a groundwater flow model in the southwest Albany area, Georgia.

Introduction

Long-term, heavy pumping from the Claiborne, Clayton, 

and upper Cretaceous (Providence) aquifers, which underlie the Upper Floridan aquifer, has resulted in significant 

water-level declines in the deeper aquifers in the Albany area 

in Dougherty County, Georgia. These declines have raised 

concern about meeting increasing demands for potable water 

supply with the deep aquifers. To meet increasing demands, 

the Albany Water, Gas, and Light (WGL) Commission has 

developed a large wellfield near Albany. The supply wells 

primarily tap the Upper Floridan aquifer, a highly productive 

and porous limestone aquifer, which is the uppermost reliable ground-water source in this area. Because of the karstic 

landscape and local recharge to the aquifer, water quality may 

be affected by local and regional land use. To address concerns about the quality and availability of ground water in the 

Albany area, the U.S. Geological Survey (USGS) and WGL 

initiated a cooperative water program during 1977.

Analysis of nitrate in a water sample collected from a 

school supply well located southwest of Albany indicated concentrations exceeded the 10 milligrams per liter (mg/L) maximum contaminant level (MCL) set by the U.S. Environmental 

Protection Agency (U.S. Environmental Protection Agency, 

2000a). Concern about nitrate contamination prompted the 

Dougherty County Health Department to sample more than 

700 existing wells (including all residential wells near the 

school) for nitrates during 1997. Water from 12 percent of 

these wells had nitrate concentrations above the MCL (Susan 

Reyher, Dougherty County Health Department, oral commun., 

1999). Each of the contaminated wells is completed in the 

Upper Floridan aquifer, which supplies water for most of the 

domestic and irrigation wells in the southwest Albany area. 

Cooperative Water Program

The Federal-State Cooperative Water Program (CWP) is 

a partnership between the USGS and State and local agencies 

that provides information that forms the foundation for many 

of the Nation’s water-resources management and planning 

activities. In addition, the information may function as an 

early warning for emerging water problems. Having the USGS 

involved results in consistent techniques of data collection and 

archiving, with the information stored in a common database 

readily available to all. The knowledge gained in the studies is 

published and added to the growing body of information about 

the hydrology of the region or area.

The objectives of the Albany CWP are to (1) augment the 

current level of understanding of the hydro­geologic framework of the Upper Floridan aquifer in the Albany area of 
southwestern Georgia, (2) monitor water-level fluctuations in 

the four aquifers used in the area and relate water-level trends 

to changes in climatic conditions and pumping patterns, and 

(3) evaluate and monitor water quality in the Upper Floridan 

aquifer as pumping patterns and land-use activities change. 

These objectives are being met by the following tasks:

•	 Water-quality monitoring near the southwestern 

Albany-area wellfield. 

•	 Ground-water-level monitoring—operation and maintenance of 14 continuous water-level monitoring wells 

in four aquifers and measurement of water levels in 

about 70 wells annually (during Fall). 

•	 Maintaining USGS National Water Information 

System (NWIS) database, which includes groundwater, surface-water, and water-quality data.

•	 Ground-water-flow modeling in the Upper Floridan 

aquifer to simulate nitrate migration and travel times.

This annual summary presents an overview of significant 

accomplishments and technical findings during July 2005 

through June 2006 and plans for fiscal year 2007. Also 

included is an overview of hydrologic conditions during 2005 

that includes summaries of ground-and surface-water conditions, and a summary of water-quality data collected and/or 

analyzed in 2005–06. Hydrographs of water levels and statistics from selected wells are presented in the Appendix.

Related Studies

During July 2005 through June 2006, the USGS was 

involved in the lower Apalachicola–Chattahoochee–Flint 

(ACF) River Basin ground-water modeling study in co­operation with the Georgia Department of Natural Resources, 

Environmental Protection Divi­sion (GaEPD). The major 

objective of that study was to develop a transient finiteelement model of ground-water flow to simulate the impact 

of agricultural pumping on stream-aquifer interaction. Two 

scientific investigation reports were published from that study: 

Torak and Painter, 2006 and Jones and Torak, in press.

Progress during Fiscal Year 2006

During fiscal year 2006 (FY06), activities conducted for 

this program include:

• Continued ground-water-level monitoring. The USGS 

has been maintaining continuous water-level recorders on 24 wells, 14 of which are funded by the Albany 

CWP and 10 of which are funded by other projects. 

Water levels in five additional wells are measured 

monthly (fig. 1, table 1). Summaries of local waterresources conditions are published biannually in the 

USGS report, “Ground-water conditions and studies 

in Georgia” and annually in the USGS report “Waterresources data for Georgia.” See section “GroundWater Conditions” and the Appendix for groundwater-level hydrographs and statistics for selected 

wells. All data are available on the Web at http://

waterdata.usgs.gov/ga/nwis/dv?referred_module=gw

(accessed June 30, 2006).

• Constructed water-level (potentiometric-surface) map 

for the Upper Floridan aquifer near the new wellfield. 

Water-level measurements were collected from 70 wells 

in the southwest Albany area during October 4–6, 

2005, and a water-level map was constructed (fig. 2). 

The map indicates that water generally flows from 

northwest to southeast near the wellfield. No cone of 

depression is visible at the wellfield. All data are available on the Web at http://waterdata.usgs.gov/ga/nwis/

dv?referred_module=gw (accessed June 30, 2006).

• Updated annual potentiometric-surface maps for 1998 

through 2005. The Dougherty County Engineering 

Department surveyed the USGS Albany wellfield-area 

well network to facilitate construction of more accurate 

potentiometric-surface maps. The revised maps will 

provide more accurate input data for the ground-water 

flow model. The maps will be published in the next 

“Ground-water conditions and studies in Georgia” 

biannual report.

• Continued water-quality monitoring.

•	 Water samples were collected from 17 wells in 

the southwest Albany area, November 8–11, 2005, 

and were analyzed for cations, anions, and nutrients. 

Nitrate values are presented in figure 3.

•	 To compare the water-quality characteristics of 

ground water and surface water, a sample was 

collected from the Flint River on November 10, 

2005. A trilinear diagram showing the percent 

composition of selected major cations and anions 

is presented in figure 4.

• Continued maintenance of Albany area hydrologic 

databases. The USGS continued updates to the 

National Water Information System database, including ground-water-level and water-quality data and well 

site information. All data are available on the Web at 

http://waterdata.usgs.gov/ga/nwis/dv?referred_

module=gw (accessed June 30, 2006).

•	 Began Albany wellfield area ground-water-flow 

model. Data was put into the model. The model was 

run using the original model area and grid spacing. 

The model area was expanded east of the Flint River 

and the grid spacing was refined to better capture flow 

in the Albany wellfield area. The new area and grid 

spacing is shown in figure 5. Two additional layers 

were added to the model to account for the surficial 

aquifer and the confining layer separating the surficial 

and Upper Floridan aquifers (fig. 6). See section on 

Albany wellfield area flow model for more details.

•	 Continued to map sinkholes at the wellfield. Gary 

Morefield (of WGL) provided location of two sinkholes that formed during 2005 (one on April 6, 2005, 

and one on August 23, 2005). These sinkholes were 

plotted on a map of the wellfield (fig. 7).

•	 Updated Albany area Web site. The Web site was

Albany Wellfield-Area Flow Model

To improve the understanding of the ground-water flow 

system and nitrate movement in the Upper Floridan aquifer, 

the USGS is developing a ground-water flow model in the 

wellfield area. Although ground-water-flow models have been 

previously developed in southwest Georgia, these models are 

regional in scope and need to be refined to include greater 

detail in the wellfield area. The USGS finite-difference 

ground-water flow simulator, MODFLOW-2000 (Harbaugh 

and others, 2000) is being used for modeling.

Initially, a single-layer flow model was developed in the 

wellfield area using existing data. This preliminary model 

had a grid spacing of 500 by 500 feet (ft) and did not extend 

east of the Flint River. Running several simulations with this 

model indicated that because it was very generalized, it did not 

adequately represent the ground-water flow in the area. Three 

layers would be necessary to estimate ground-water flow and 

travel times for nitrate migration and the model boundary must 

extend east of the Flint River to simulate flow to (or from) the 

river adequately.

The three-layer model includes the surficial aquifer, the 

confining unit that separates the surficial and Upper Floridan 

aquifers, and the Upper Floridan aquifer. The model includes 

the area east of the Flint River, and a grid spacing that gradually increases from 500 by 500 ft around the wellfield to 

5,000 by 5,000 ft outside of the wellfield area (fig. 5). This 

model includes water-level, water-quality, and aquifer-parameter data from the wellfield area that have not been used in 

previous models. The model is being calibrated to October 

1999 conditions using ground-water-level data, because October 1999 was a drought period. The calibrated model will be 

used to determine ground-water flowpaths and potential movement of nitrate-contaminated water. Predictive simulations 

using a variety of pumping and boundary conditions will be 

used to assess potential pathways for nitrate migration and the 

potential for the Flint River to contribute water to the wellfield.

Accurate information on ground-water levels and the 

depth and thickness of hydrogeologic units is important for 

ground-water model development. Improved accuracy of 

land-surface altitudes was provided through a field survey 

conducted by the Dougherty County Engineering Department. These data were used to compute altitudes of the tops 

of hydrogeologic units and ground-water levels. An east-west 

cross section showing model layers was prepared based on 

these data (fig. 6).

Albany Wellfield-Area Flow Model 
Hydrologic and WaterQuality Monitoring

The Hydrology and water quality of the area were 

monitored throughout the year. The ground-water conditions, 

surface-water conditions, and water quality are described below.

Ground-Water Conditions, 2005

Ground-water levels in the Albany area are continuously 

monitored in 14 wells as part of the WGL cooperative study 

and in 10 additional wells in conjunction with other projects 

(fig. 1, table 1). Water levels are measured in an additional 

five wells on a monthly basis. All data are available on the 

Web at http://waterdata.usgs.gov/ga/nwis/dv?referred_

module=gw (accessed June 30, 2006). Of the 29 monitoring 

wells, 15 are completed in the Upper Floridan aquifer, five in 

the Claiborne aquifer, six in the Clayton aquifer, one in the 

Providence aqui­fer, and two in the surficial aquifer (fig. 1, 

table 1). Hydrographs showing annual daily mean (2005) 

water levels, monthly water level statistics, and monthly mean 

water levels for the period of record in selected wells are 

shown in the Appendix.

Water-level measurements were collected from 70 wells 

in the southwest Albany area during October 4–6, 2005, and 

a potentiometric-surface map was constructed (fig. 2). The 

map indicates that water generally flowed from northwest 

to southeast and a cone of depression is not visible at the 

wellfield. Water levels in the Upper Floridan aquifer generally 

were above normal during 2005. Of the 14 wells continuously 

monitored in Dougherty County, water levels in eight were 

above normal and water levels in six were normal (fig. 2).

Hydrographs for selected wells are presented in the 

Appendix. Water levels in most of the wells show a rise 

starting during 2002 that continues through 2005. This rise 

is the result of the end of the drought for 1998 through 2002. 

Water levels in most of the wells in the Clayton and Claiborne 

aquifers have been declining since the late 1970s. During the 

past few years however, water levels have increased in some of 

these wells (wells 12M002 and 11L002, for example). Water 

levels in the Clayton aquifer are monitored in six wells in the 

Albany area (fig. 1, table 1). During 2005, water levels in two 

of these wells were above normal, three were normal, and one 

was below normal (Appendix). A record high water level was 

recorded in well 12L020 (Clayton aquifer) during January 

2005. Water levels in the Claiborne aquifer are monitored in 

three wells (fig. 1, table 1), all of which were above normal 

during 2005 (Appendix). The water level in the Providence 

aquifer is measured in well 12L021 (fig. 1, table 1), the water 

level in this well was above normal for 2005.

Surface-Water Conditions, 2005

The Albany area contains two real-time streamgages 

(see Web site, http://waterdata.usgs.gov/ga/nwis/rt, accessed 

June 15, 2006). These gages are located on the Flint River 

at Albany (02352500) and Chickasawhatchee near Leary 

(02354410) (fig. 1). The Flint River gage at Albany was 

installed during 1901; the gage at Chickasawhatchee near 

Leary is newer, installed during May 2001. Stream stage 

and discharge data are shown for these sites on the Web site. 

Figure 8 presents daily discharge data for the Flint River at 

Albany for July 2005 through May 2006. The data show that 

discharge was above normal during the summer of 2005, then 

below normal for most of 2006, through May (fig. 8). 

Ground-Water Quality, 2005

Water samples were collected from 16 wells in the 

southwest Albany area during November 8–11, 2005, and 

were analyzed for cations, anions, and nutrients (fig. 3). Of the 

16 samples collected, two had nitrate as nitrogen concentration 

greater than the 10 mg/L MCL (well 12L061 completed in the 

Upper Floridan aquifer and 12L376 completed in the surficial 

aquifer). Since November 2004, nitrate levels have increased 

in 13 wells and decreased in two wells. The increased nitrate 

levels are probably related to increased recharge from rainfall 

in the summer and fall of 2005.

To compare the water-quality characteristics of ground 

water and surface water, a sample was collected from the Flint 

River on November 10, 2005. A trilinear diagram showing 

the percent composition of selected major cations and anions 

is presented in figure 4. This diagram shows that the groundwater quality of the Upper Floridan aquifer near the wellfield 

is distinctly different from the water quality of the Flint River.

Additional Data Needs

Expanded monitoring and characterization of the geologic and hydrologic properties of the surficial aquifer would 

facilitate understanding of the nitrate contamination problem 

and provide data necessary for model development. During 

fiscal years 2005 and 2006, monthly water levels were collected from the surficial aquifer from two wells. The USGS 

proposes collecting additional water-quality and water-level 

data from the surficial aquifer. Specifically, shallow wells 

could be drilled in and near the wellfield to provide improved 

characterization of the surficial aquifer and underlying confining unit. These wells would facilitate:

• Collection of borehole geophysical logs in 

completed boreholes,

• Conducting aquifer tests in selected wells to determine 

hydraulic properties of the surficial aquifer,
