PFAS-Confirmed Superfund Sites in Maine

The list below is a statewide screening tool, not an address check. A Superfund site somewhere in Maine doesn't mean a specific home is affected, and no nearby site isn't a promise about your soil or water. Maine's contamination history is comparatively light on heavy industry, leaning instead toward legacy mill sites, tanneries, and military presence, which shapes the kinds of sites that surface here. The federal program drives the list; the Maine Department of Environmental Protection (Maine DEP) is the state's active cleanup partner. Treat it as context worth reviewing when evaluating an address, and let the public records, rather than the weight of the word, set your expectations.

Who manages contaminated-site cleanup in Maine

Federal Superfund cleanups in Maine have a committed state-side partner in the Maine Department of Environmental Protection (Maine DEP), which works with the U.S. EPA on contaminated-site work and runs its own state tracks for uncontrolled sites and voluntary response actions outside the federal list. Maine has also been among the more forward states on PFAS generally, which can carry over to how it approaches the chemicals at contaminated sites alongside the federal program. The reassurance to hold onto: behind the word 'Superfund' in Maine is an active, named state office, not just a federal acronym.

12 PFAS-confirmed Superfund sites in Maine

From EPA's National Priorities List, filtered to sites with confirmed PFAS contamination. EPA's broader Superfund/SEMS inventory is larger and includes non-PFAS and assessment-stage sites.

What this Mainelist does — and doesn't — tell you

A blank PFAS-confirmed list is not a clean bill of health. It means no Maine Superfund site has been confirmed for PFAS in the records we use, not that none exists, and given how actively Maine has pursued PFAS, the picture can shift. Maine DEP and EPA track a far broader SEMS inventory of contaminated and remediated sites, and PFAS confirmation often trails the testing. Read a quiet list as 'nothing flagged on this narrow measure,' not as a guarantee.

A site appearing on this page means EPA has confirmed PFAS contamination at a National Priorities List Superfund site somewhere in Maine. It is a statewide screening list. It does not tell you the distance from any specific home, the exposure pathway, or whether the local drinking-water system is affected.

For a specific property, the things that actually matter are:

  • Distance to the nearest site — risk generally drops sharply with distance.
  • Contamination type & pathway — groundwater PFAS matters most if the home draws from a private well or an affected public system.
  • Cleanup stage— active vs. “construction complete” vs. deleted.
  • The home's water source— pair Superfund proximity with the property's drinking-water and PFAS data.

That address-level synthesis — nearest-site distance plus the home's full environmental profile in one A–F grade — is what the VetMyAddress report is for.

Superfund & PFAS in Maine: common questions

Who oversees Superfund cleanup in Maine?

Superfund is led federally by the U.S. EPA, but the Maine Department of Environmental Protection (Maine DEP) is the state-side partner, co-managing cleanups and tracking contaminated sites across Maine. Maine DEP also runs its own remediation programs for uncontrolled sites and voluntary actions outside the federal list, and it has been notably active on PFAS. Oversight is shared, with an engaged named state office.

What is a Superfund site?

A Superfund site is a place the federal government has flagged as contaminated enough to require long-term cleanup under the law often called CERCLA, with the most serious added to the National Priorities List. In Maine, the U.S. EPA and the Maine Department of Environmental Protection (Maine DEP) work together on those cleanups. Being on the list signals known contamination and an active process, not a fixed verdict on every nearby home.

How many PFAS-confirmed Superfund sites are in Maine?

Our curated EPA dataset lists 12 PFAS-confirmed Superfund (NPL) sites in Maine, including Brunswick Naval Air Station, Eastern Surplus, Eastland Woolen Mill. EPA's full Superfund inventory (including non-PFAS and assessment-stage sites) is larger — a specific-address report checks all SEMS sites near the property.

Does a nearby Superfund site affect a Maine home?

Proximity is a starting point, not a verdict. Real-world impact depends on distance, the type of contamination, the exposure pathway (groundwater, soil, vapor), the home's water source, and the cleanup stage. A site two miles away marked 'construction complete' is very different from an active site next door.

How do I check Superfund sites for a specific Maine address?

Use VetMyAddress to see EPA Superfund/NPL sites near any Maine address, bundled with the home's drinking water, PFAS, flood zone, and air-quality data in a single plain-English A–F grade. EPA's own ECHO database (echo.epa.gov) is the free, official source if you prefer to dig through the raw records.

What does 'PFAS-confirmed' mean for an NPL site?

It means PFAS ('forever chemicals') have been documented in the contamination at that National Priorities List site. PFAS is persistent and can migrate through groundwater, so a confirmed PFAS site is worth pairing with the home's drinking-water and PFAS data to understand the exposure pathway.
