Prepared in cooperation with the Albany Water, Gas, and Light Commission
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 an overview of ground-water conditions and studies in the Albany area of Dougherty County, Georgia, during 2007. Historical data are also presented for comparison with 2007 data. Ongoing monitoring activities include continuous water-level recording in 24 wells and monthly water-level measurements in 5 wells. During 2007, water levels in 21 of the continuous-recording wells were below normal, corresponding to lower than average rainfall. Ground-water samples collected from the Upper Floridan aquifer indicate that nitrate levels have decreased or remained about the same since 2006.
Water samples were collected from the Flint River and wells at the Albany wellfield, and data were plotted on a trilinear diagram to show the percent composition of selected major cations and anions. Ground-water constituents (major cations and anions) of the Upper Floridan aquifer at the Albany wellfield are distinctly different from those in the water 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 ground-water flow model in the southwestern Albany area of Georgia. The model is being calibrated to simulate periods of dry (October 1999) and relatively wet (March 2001) hydrologic conditions. Preliminary water-level simulations indicate a generally good fit to measured water levels.
