This study was conducted by Friends of the Shenandoah River with cooperation of Clarke County and the willingness of landowners who gave access to the springs. Funds for the study were granted to Alison Teetor by the 2013 Citizen Water Quality Monitoring Grant Program, from the Virginia Department of Environmental Quality, and from the Chesapeake Bay Restoration Fund. Chemical analyses were conducted by Karen Andersen and Molly Smith. Ben Sawyer performed GIS measurements and helped with hydrologic analyses. John Young USGS Leetown, WV loaned a stream flow meter. Richard Marzolf helped write this report.
