Virginia's 2010 NonPoint Source (NPS) Pollution Assessment and Prioritization Data Type Selection Form


The 2010 NPS Pollution Assessment and Prioritization results contain three types of evaluations: modeled NPS pollutant loadings (nitrogen, phosphorous, and sediment), measures of impaired waters (rivers and lakes/reservoirs), and biological priorities (source water and aquatic biodiversity protection). All are available at the 6th order hydrologic unit level of the National Watershed Boundary Dataset.
