The Agency for Toxic Substances and Disease Registry (ATSDR) Hazardous Waste Site Polygon Data, Version 2 consists of 2,080 polygons for selected hazardous waste sites that were created on or before May 26, 2010. Most polygons represent sites considered for cleanup under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or Superfund). Typical sites are either on the EPA National Priorities List (NPL) or are being considered for inclusion on the NPL. The hazardous waste site boundaries maintained by the Geospatial Research, Analysis, and Services Program (GRASP, Division of Health Studies, Agency for Toxic Substances and Disease Registry, Centers for Disease Control and Prevention) contain NPL and non-NPL hazardous waste site boundaries for which health assessments or consultations have been requested.
The GRASP Team maintains site boundary data using the best available information. The data set was first obtained in response to a request by the National Institute of Environmental Health Sciences to conduct an assessment of populations living in proximity to NPL sites (NIEHS, HHSN273200800139P).
