A multi-year record of chemical and isotopic composition of water from springs of the Shenandoah National Park, Virginia
From 1994 through 2017, the U.S. Geological Survey in cooperation with the National Park Service, Luray, Virginia Station collected and analyzed samples of selected springs, air and unsaturated-zone gases in Shenandoah National Park, Virginia. These data include field measurements of water temperature, specific conductance, concentrations of dissolved oxygen (O2), and pH. Laboratory measurements included major-, minor-, and trace-element chemistry; concentrations of dissolved gases (nitrogen, [N2] argon [Ar], oxygen, and carbon dioxide [CO2]); concentrations of dissolved trace atmospheric gases, including trichlorofluoromethane (CFC-11), dichlorodifluoromethane (CFC-12), and trichlorotrifluoroethane (CFC-113) and sulfur hexafluoride (SF6); and hydrogen stable isotopic composition (δ2H) and oxygen isotopic composition (δ18O) of water. The data include an up to multi-year time series record of monthly sampling at five springs collected between 1995 and 2013. The measurements included temperature, specific conductance, pH, and discharge recorded at 30-minute intervals. Atmospheric mixing ratios of CFC-11, CFC-12, CFC-113, trifluorobromomethane (CF3Br), SF6, and trifluoromethyl sulfur pentafluoride (SF5CF3) in air from the Big Meadows Air Monitoring Station, Shenandoah National Park, were measured at approximately weekly intervals from September 1995 through April 2017.
