Pollution & Cleanup
Read this first: what follows is a statewide screening list, not an address check. A documented site somewhere in Idaho says nothing definitive about a particular home, which may sit many miles away. Idaho's contamination history leans heavily on its mining legacy, especially in the older hard-rock districts, alongside scattered manufacturing and federal land uses. The Idaho Department of Environmental Quality partners with EPA's federal Superfund program on these sites as the state-side authority. Use the records here as context worth reviewing when evaluating an address, never as a safety verdict. They reflect what the public files document, and that is all.
For contaminated-site cleanup, the Idaho Department of Environmental Quality (DEQ) serves as the state-side partner to EPA's federal Superfund program, co-managing listed sites and typically running state-level remediation work of its own. Idaho's PFAS handling at contaminated sites tends to track the federal framework rather than a distinct state standard, in step with how the state approaches PFAS in drinking water. The point is grounding: behind the word Superfund there is a named state office, not only a distant federal one.
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.

| Mountain Home Air Force Base | Federal · NPL: Final |

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 appear for Idaho in these records, that is reassuring, but it is not a complete all-clear. PFAS confirmation reflects only what has been tested and reported so far, and the Idaho Department of Environmental Quality's wider contaminated-site work, together with EPA's SEMS inventory, spans much more than this single view. Read an empty list as encouraging, with the caveat that it is not the whole story.
A site appearing on this page means EPA has confirmed PFAS contamination at a National Priorities List Superfund site somewhere in Idaho. 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.
The Idaho Department of Environmental Quality (DEQ) is the state-side partner to EPA's federal Superfund program. The two co-manage contaminated-site cleanup in Idaho, with the state agency typically leading state-level remediation alongside the federal listings.
Idaho has federally tracked contaminated sites, shaped in large part by its mining legacy and scattered industrial and federal land uses. The table above renders the documented sites from public records, with the Idaho Department of Environmental Quality co-managing cleanup alongside EPA.
The Idaho Department of Environmental Quality (DEQ) is the state's environmental agency. On the cleanup side it works with EPA's federal Superfund program and oversees state-level site remediation across Idaho.
Our curated EPA dataset lists 2 PFAS-confirmed Superfund (NPL) sites in Idaho, including Idaho National Engineering Laboratory (Usdoe), Mountain Home Air Force Base. 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.
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 Idaho 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.
