Eight drinking water suppliers in the Potomac River Basin Drinking Water Source Protection Partnership (DWSPP) collaborated to rank land parcels to protect drinking water quality. Participating utilities included (in order from upstream to downstream) Berkeley County Public Service Water District, Frederick County Division of Water and Sewer Utilities, the Town of Leesburg Department of Utilities, Loudoun Water, Fairfax Water, Washington Suburban Sanitary Commission (WSSC Water), Washington Aqueduct, and DC Water. The project area encompassed the non-tidal Potomac basin above the DC metro drinking water supply intakes. |

<DIV STYLE="text-align:Left;"><DIV><P><SPAN>The raster-scale cumulative prioritization represents the cumulative prioritization value of all metrics. The raster cell values of the seven metric rasters included in this geodatabase were summed using equal weights except for karst transmissivity. Karst transmissivity received a weight of 0.5 (or 50 percent) because the metric tended to dominate all other values where it was present. </SPAN></P><P><SPAN>The raster was normalized on a scale from 0 to 100, with a value of 100 indicating the highest priority for conservation. The “Geomorphometry & Gradient Metrics Toolbox” developed by Evans and Cushman (2014) was used for the normalization procedure. The toolbox is available at https://github.com/jeffreyevans/GradientMetrics. Accessed 3/9/2020.</SPAN></P></DIV></DIV> |
