The chemical and isotopic composition of water discharging from 44 springs and 32 wells in Shenandoah National Park (SNP) and vicinity were measured. The data include field measurements of water temperature, specific conductance, concentrations of dissolved oxygen (O2), and pH, and laboratory measurements of major- minor- and trace-element chemistry, concentrations of dissolved gases (nitrogen (N2), argon (Ar), helium (He), neon (Ne), oxygen (O2), and carbon dioxide (CO2)), tritium (3H) of water, concentrations of dissolved trace atmospheric gases, including chlorofluorocarbons (CFC-11, CFC-12, and CFC-113), and sulfur hexafluoride (SF6), the 3He/4He isotope ratio (53He) of dissolved He, stable ^'H and 18O/16O isotope ratios (52H and 518O) of water, the stable 34S/32S isotope ratio (534S) of dissolved sulfate, the stable 15N/14N isotope ratio (515N) of dissolved nitrate, and the activity of radioactive sulfur-35 (35S) of dissolved sulfate. Water from selected springs and wells was sampled in April 1996, August-September 1997, and August- September 1999. Additional data on the atmospheric mixing ratios of CFC-11, CFC-12, CFC-113 and SF6 in air from the Big Meadows Air Monitoring Station, SNP are given approximately weekly for the period September 1995 through March 2000.
