Land Owl maps Superfund sites from the U.S. Environmental Protection Agency's CERCLA record, including sites on the National Priorities List, sites proposed for it, and sites deleted from it after cleanup. A deleted site is one EPA has determined needs no further federal response; it is not a statement that the site was never contaminated, and its history still appears in a Phase I environmental site assessment.

Does a nearby Superfund site affect a property?

It can, and it is a standard question in a Phase I environmental site assessment — the screen a lender orders before financing commercial land. Proximity alone is not contamination, but a listed site nearby is a reason to ask what the plume is, where it is going, and what EPA's record says.
