Source water vulnerability to elevated total dissolved solids within a mixed-use Appalachian River basin
Fig 1
Location of sites used to model spatial (n = 885) patterns in total dissolved solids (TDS) within 8-digit hydrologic unit code (HUC) watersheds comprising the upper Monongahela River basin within West Virginia and Pennsylvania.
Sites are separated into those where TDS was measured and those where TDS was estimated as a function of specific conductivity. Location of drinking water intakes (n = 32) are also shown. Spatially mapped data for the state boundaries, hydrologic unit code watersheds, rivers, reservoirs, and drinking water intakes was obtained from the WV GIS Tech Center (wvgis.wvu.edu).
