New Data Available in EPA’s Nitrogen and Phosphorus Pollution Data Access Tool

Aug. 15, 2015
EPA has added updated data in the NPDAT, a tool intended to help states develop effective nitrogen and phosphorus source reduction strategies. The data layer “Facilities Likely to Discharge Nitrogen/Phosphorus (N/P) to Water” now provides information on N/P discharges from 2014 facility monitoring reports (previously 2013 information was the most current information available through the EPA’s data access tool) and corresponding nitrogen and phosphorus limits from EPA’s Discharge Monitoring Report (DMR) Pollutant Loading Tool.  Second, the “Waters Listed for N/P Impairments” and “Waters with N/P Total Maximum Daily Loads (TMDLs)” data layers now reflect data pulled from the Assessment TMDL Tracking and ImplementatioN System (ATTAINS) as of May 2015 (previously the layers reflected 2014 ATTAINS data).  Third, the “Drinking Water Sources” HUC12 Density data layer provides information on surface and ground water sources as of (quarter 4) 2014 (previously the layer reflected 2010 data).
