Superfund sites, by where the cleanup stands

The National Priorities List is EPA's list of the worst hazardous-waste sites in the country. A site on it is not necessarily dangerous today — half were listed in the 1980s, and most of those cleanups are built. What tells you about now is the cleanup stage and EPA's two “under control” findings.

21Proposed164Listed34Remedychosen367Cleanupunderway271Constructioncomplete516Readyfor reuse
1,374 sites by the furthest stage reached, from EPA site profiles.
Human exposure114 siteswhere EPA says people's exposure to the contamination is not under control.
Groundwater206 siteswhere EPA says contaminated groundwater is still migrating.

Of 1,374 sites, EPA has a yes-or-no finding on human exposure for 1,149 and on groundwater for 1,032; the others are “insufficient data”, not a groundwater site, or left blank. See the sites →

When sites were listed

The 1980s list is mostly built. Newer sites are mostly not.
