ABSTRACT
The carbonate aquifer system of the northern Shenandoah Valley provides an important water supply to local
communities, including Frederick County, Va., which depends on ground water as a source of water supply.
The county and surrounding area are undergoing increased urbanization, and increased demands on the carbonate
aquifer system are expected. A study was conducted between October 2000 and March 2004 by the U.S. Geological
Survey (USGS), in cooperation with the County of Frederick, Va., to describe the hydrogeology and ground-water
availability in the carbonate aquifer system underlying the county. The study area encompasses about 25 percent |
