Pollution & Cleanup
The word Superfund lands hard, so let's keep this measured. What you see below is a statewide screening list, not an address check, and a site somewhere in Montana does not mean a particular home is affected. Montana's industrial story leans heavily on a long mining and resource-extraction legacy, which shapes much of what shows up in this kind of record. Cleanup here is co-managed: the federal EPA runs the national Superfund program, and the Montana Department of Environmental Quality (DEQ) is the state-side partner. Use this page to understand what the public records show across the state, and treat a specific address as its own separate question worth reviewing on its own.
Montana's cleanup work is shared between the federal EPA and the Montana Department of Environmental Quality (DEQ), which acts as the state-side partner on Superfund and runs a state-level contaminated-site and remediation program of its own. The DEQ helps oversee long-running cleanups and tracks sites that never reach the federal list. On PFAS at contaminated sites, Montana tends to follow the federal program rather than imposing its own separate site cleanup numbers. The reassuring part of a heavy word like Superfund: there is a named office co-managing the work alongside EPA, not just a federal file in a distant drawer.
No PFAS-confirmed NPL Superfund sites listed in Montana
Our curated dataset of PFAS-confirmed National Priorities List sites currently shows none in Montana. That's reassuring on the PFAS-Superfund front, but not a full all-clear: EPA's broader Superfund/SEMS inventory includes many non-PFAS and earlier-stage sites that aren't in this list. To see every EPA Superfund site near a particular Montana property — plus its water, PFAS, flood, and air profile — check the specific address.

VetMyAddress maps nearby EPA Superfund/NPL sites and grades the address A–F alongside its water, PFAS, flood, and air data.
If no PFAS-confirmed Superfund sites turn up for Montana, that is genuinely good to see, but it is not a full all-clear. The Montana DEQ and EPA track a much broader SEMS inventory than the PFAS-confirmed subset, and a quiet list mostly means this particular slice is empty here, not that every site has been ruled out. It is a reassuring starting point, not a closing argument.
A site appearing on this page means EPA has confirmed PFAS contamination at a National Priorities List Superfund site somewhere in Montana. 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:
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 cleanup in Montana is co-managed by the federal EPA, which runs the national program, and the Montana Department of Environmental Quality (DEQ), which serves as the state-side partner and runs its own state site-remediation work. The two coordinate on long-running cleanups across the state.
A Superfund site is a location placed on the federal National Priorities List because contamination there warrants long-term cleanup. In Montana, many of these trace back to the state's mining and resource-extraction history, and the Montana DEQ partners with EPA to oversee the work.
The Montana Department of Environmental Quality, or DEQ, is the state agency that protects Montana's land, air, and water and acts as the state-side partner to EPA on contaminated-site cleanup, including Superfund sites.
Our curated dataset of PFAS-confirmed NPL Superfund sites currently lists none in Montana. That is not a clean bill of health: EPA's broader Superfund/SEMS inventory includes many non-PFAS and assessment-stage sites. A specific-address report checks the full EPA SEMS database near the property.
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.
Use VetMyAddress to see EPA Superfund/NPL sites near any Montana 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.
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.
