Abstract

Proceedings of the 2001 Georgia Water Resources Conference, April 26 and 27, 2001, Athens, Georgia.The U.S. Geological Survey is investigating:the potential for implementation of several Aquifer Storage Recovery systems on the Charleston, South Carolina, peninsula. A pilot study, conducted in the Santee Limestone Black Mingo aquifer during 1993-95, indicated that the recovery efficiency, based on the national drinking-water standard for chloride, varied between 38 and 61 percent during nine Aquifer Storage Recovery cycles. A second study, initiated in 1998 at a site in downtown Charleston, is evaluating the geochemical and hydrologic effects of storing potable water in the aquifer for 1 to 6 months. reliminary results from cycles with 1-month storage periods indicate recovery efficiencies as great as 81 percent. Decreased transport time from the production well to observation wells has been observed, indicating a probable increase in the permeability of the aquifer. Analysis and geochemical modeling of water-quality data collected from the site wells are planned to determine the dominant geo-chemical reactions, taking place during Aquifer Storage Recovery cycling in the aquifer.Sponsored and Organized by: U.S. Geological Survey, Georgia Department of Natural Resources, Natural Resources Conservation Service, The University of Georgia, Georgia State University, Georgia Institute of TechnologyThis book was published by the Institute of Ecology, The University of Georgia, Athens, Georgia 30602-2202.
