About This Data
Superfund sites are contaminated locations in the U.S. designated by the EPA for cleanup under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). These sites contain hazardous substances that pose risks to human health and the environment. The National Priorities List (NPL) identifies the most serious sites eligible for federal cleanup funding.
The TRI is a publicly available EPA database that tracks the management of certain toxic chemicals by industrial and federal facilities. Facilities must report annually how much of each chemical is released to the environment or otherwise managed. The data covers over 650 chemicals and chemical categories across multiple industry sectors.
All environmental data comes from the U.S. Environmental Protection Agency (EPA). Superfund site data is sourced from the EPA's Superfund Enterprise Management System (SEMS). Toxic release data comes from the EPA's Toxics Release Inventory (TRI) annual reporting program established under the Emergency Planning and Community Right-to-Know Act (EPCRA).
