Scorecard currently profiles risks to public health and the environment from only two potential sources of land contamination in the U.S.: toxic waste sites identified as federal Superfund sites, and manufacturing facilities reporting land and underground releases of chemicals to the Toxics Release Inventory.
Data Source: Scorecard's profiles of Superfund sites are derived from multiple sources dating from 1993 to 2000. Primary sources include: NPL Fact Sheets maintained by EPA regions, and four EPA databases: the Superfund National Assessment Program (SNAP), the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) database in Envirofacts; the Potentially Responsible Party (PRP) database; and the Remedial Program Managers (RPM) database. For profiles of TRI manufacturing facilities, Scorecard utilizes data from the most recent U.S. EPA Toxics Release Inventory (TRI).
Note: Scorecard's profiles of Superfund sites include only proposed and final sites on the National Priorities List. Numerous other sources of land contamination, such as state superfund sites, brownfields, nonhazardous waste disposal facilities, and other land contamination sources are not currently profiled because they are not tracked in national datasets. Scorecard reports on TRI manufacturing plants cover only those required to report for the 1997 TRI, and only 650 listed TRI chemicals.
