The Superfund proximity indicator is reflective of the total count of sites proposed and listed (final) on
the National Priorities List (NPL) in each block group within 5 km of the average resident in a block
group, divided by distance, calculated as the population-weighted average of blocks in each block group.

Brownfield Sites
This layer displays the locations of the Environmental Protection Agency (EPA) Assessment, Cleanup and Redevelopment Exchange System (ACRES) sites. ACRES stores information reported by EPA Brownfields grant recipients on brownfields properties assessed or cleaned up with grant funding as well as information on Targeted Brownfields Assessments performed by EPA Regions. A brownfield site consists of land previously used for industrial purposes or some commercial uses. The land may be contaminated by low concentrations of hazardous waste or pollution, and has the potential to be reused once it is cleaned up. For more information, please visit the EPA Brownfields and Land Revitalization website or the ACRES Information web page.
