Hydrogeochemical characterization of springs and wells in the Cacapon Mountain Aquifer.

摘要

The Cacapon Mountain Aquifer is located near Berkeley Springs in Morgan County, West Virginia. Approximately 120 wells were selected for a synoptic survey of data including static water levels, pHs, specific conductances, and temperatures to assess regional hydrogeology and geochemistry. Six springs and four wells were sampled on a monthly basis to identify their hydrochemical types and infer the geology of their recharge areas. The potentiometric surface obtained at wells was found to be a subdued reflection of topography. The geologic structure was determined to generally control the direction of ground water flow. Ground water was transmitted in a cross-strike direction on the slopes and in an along-strike direction in Cold Run Valley, parallel to the trend of Cacapon Mountain. Springs could be categorized into two hydrochemical groups; reflecting either a carbonate or siliceous source. Although water from Ladies' Spring was much warmer than all other springs, it was chemically very similar to the carbonate-derived spring waters.
