Modeled 6PPD-quinone sources within NHDPlusV2 catchments of the Anacostia River watershed

These data were created to support a geonarrative of the Anacostia River watershed's modeled 6PPDQ sources, which was funded by the Washington D.C. Department of Energy and Environment (DOEE), Chesapeake Bay Priority Ecosystem Studies, and USGS Cooperative Matching Funds. This dataset contains a CSV file with a summary of potential sources of 6PPDQ within catchments of the Anacostia River watershed. Potential sources include roadways, bus stops, traffic signals, and rubber surfaces. Each potential source is weighted based on its expected 6PPDQ output.
