Abstract

Brackish water from Chesapeake Bay and its tributaries has entered the Aquia aquifer in east-central Anne Arundel County, Maryland, USA. This determination was made based on chloride analyses of water samples collected in wells screened in the Aquia aquifer between October 1988 and May 1989. The Aquia aquifer, which is composed of fine- to medium-grained sand, is a shallow, unconfined aquifer in this area. Land use is primarily urban, consisting of a mixture of residential and light commercial areas. Associated with the urban setting is the potential for chloride contamination to enter the Aquia aquifer from anthropogenic sources, such as residential septic-tank effluent, leaky public sewer lines, road-deicing salt, stormwater infiltration basins, and domestic water-conditioning recharge effluent.
