Communities within the Valley and Ridge Physiographic Province of West Virginia are concerned about the availability and sustainability of their water supplies. The water resources of the Wardensville area of West Virginia were investigated and data sources were reviewed that will be useful in similar resource assessments elsewhere in the region. Estimates of long-term average discharge of the Cacapon River, Waites Run, and Trout Run are 170, 21, and 78 cubic feet per second, respectively. Average flow from Wardensville Spring during the study was determined to be 0.265 cubic feet per second, and the apparent age of this water was about 20 years. Increases in springflow and drops in temperature of the water during significant winter runoff events suggest that Wardensville Spring may be under the influence of surface runoff at such times. About 80 total coliform colonies per 100 milliliters (mL) of water were found in the spring, but less than 1 colony per 100 mL of water was fecal coliform, and their source is unknown. A well completed during the study in the Marcellus Shale near the contact with the Oriskany Sandstone is capable of yielding 60 gallons per minute, and water produced from the well has an apparent age of 50 years. Iron and manganese concentrations in the well (1,680 and 114 micrograms per liter, respectively) exceeded the U.S. Environmental Protection Agency secondary maximum contaminant levels. It is likely that a well drilled about 130 feet from Wardensville Spring is hydraulically connected to the spring because pumping at the time of well completion induced drawdown at the spring. About 20 total coliform colonies per 100 mL of water were found in that well, but fecal coliform counts were less than 1 colony per 100 mL of water. Transmissivity values of the aquifer as determined at two wells completed in the Marcellus Shale near the contact with the Oriskany Sandstone on opposite sides of Anderson Ridge are 200 and 400 feet squared per day.
