Unconsolidated Deposits along the Chattahoochee River, Threatt Property, Forsyth County, Georgia
The Forsyth County Water and Sewer Authority (FCWSA) owns several land parcels adjacent to the Chattahoochee River in the southeast corner of the County. To help meet their growing water supply needs, the FCWSA requested that EGGI investigate this area to determine if the underlying unconsolidated and bedrock aquifers, if present, could yield significant volumes of potable water.
Both fractured bedrock and unconsolidated (sand and gravel) aquifers were found to be present underlying this project site. Unique to the Piedmont Geologic Setting of the region, the relatively thick unconsolidated deposits were discovered to have a significant yield potential (greater than the deeper, crystalline bedrock aquifers underlying the same land parcel). On-going efforts have focused on characterizing and evaluating the yield potential of this very productive unconsolidated sand and gravel aquifer.
EGGI has installed a series of exploratory test wells into the unconsolidated deposits and has constructed three 16-inch-diameter, pre-packed screened production wells. Tests to date have shown the potential to develop in excess of 1,000,000 gallons per day (1 mgd) of high quality groundwater that is not under the direct influence of surface water. The project is moving forward with obtaining a groundwater withdrawal permit from the EPD.
