PFAS-Confirmed Superfund Sites in Wisconsin

These are EPA National Priorities List (NPL) Superfund sites in Wisconsin with documented PFAS contamination. It's a statewide list, not an address check — the presence of a site somewhere in the state doesn't mean any specific home is affected. To know whether a site is near a particular property, check that address directly.

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

A site appearing on this page means EPA has confirmed PFAS contamination at a National Priorities List Superfund site somewhere in Wisconsin. 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.

Frequently Asked Questions

▸How many PFAS-confirmed Superfund sites are in Wisconsin?

Our curated EPA dataset lists 11 PFAS-confirmed Superfund (NPL) sites in Wisconsin, including Algoma Municipal Landfill, Better Brite Plating Co. Chrome And Zinc Shops, Lemberger Landfill, INC.. 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 Wisconsin 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 Wisconsin address?

Use VetMyAddress to see EPA Superfund/NPL sites near any Wisconsin 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.
