Index of Superfund sites by County

Index of sites by county. Find reports of each site's history and status.

This index includes all sites—those where cleanup is complete as well as those for which cleanup or assessment is in progress.

On the maps, a light blue star designates a federal Superfund site. A red star designates a state Superfund site.

If a county below does not have a linked page associated to it, there are no Superfund sites on the Register for that county.
