PFAS Reconnaissance Landscape Data

This dataset consists of summary data for potential landscape sources of per- and poly-fluoroalkyl substances (PFAS). These summary items include facilities from the Environmental Protection Agency (EPA) PFAS Analytics Tools, which were pulled from its Enforcement and Compliance History Online (ECHO), areas affected by fires (burned and urban burned areas) from Monitoring Trends in Burn Severity (MTBS), and landcover data from National Land Cover Dataset (NLCD) and Coastal Change Analysis Portal (C-CAP) around sites sampled as part of a National PFAS Tapwater Reconnaissance. These data are presented as a comma separated file, which includes summaries for all variables listed within a 5-kilometer buffer around each site, with an additional summary of burn areas within a 50-kilometer buffer. The purpose of this effort is to identify and quantify PFAS in drinking water sources at the point-of-use across the United States (US) and these data will be used to identify potential landscape-scale drivers of PFAS contamination in US tapwater (TW).
