Pollution & Cleanup
The caveat comes first: this is a statewide screening list, not an address check. A Superfund site somewhere in Arizona doesn't mean a specific home is affected — distance, geology, and a home's water source all shape what it means. Arizona's contamination history is colored by its mining legacy and pockets of aerospace and defense manufacturing, the kind of past that leaves cleanup work behind. The agency partnering with the federal EPA on that work is the Arizona Department of Environmental Quality. Reviewing this list is worth doing when you're evaluating an address — it shows what the public records hold, not a verdict on any single property.
When a contaminated site in Arizona is placed on the federal Superfund list, the state's partner in the cleanup is the Arizona Department of Environmental Quality (ADEQ). Working alongside the federal EPA, ADEQ helps oversee remediation and runs a state-level site cleanup track, including a voluntary-cleanup pathway, for properties below the federal threshold. On PFAS at contaminated sites, Arizona has tended to operate within the federal framework rather than adopting stricter state-specific rules. The reassuring part of an unnerving word: "Superfund" has a named state office behind it, and in Arizona that office is ADEQ.
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.

VetMyAddress maps nearby EPA Superfund/NPL sites and grades the address A–F alongside its water, PFAS, flood, and air data.
A statewide list is not a ruling on any one home, and it pays to read it that way. The Arizona Department of Environmental Quality works with the federal EPA on remediation, and four down-to-earth questions decide whether a listed site bears on a particular address. Superfund speaks its own acronym-heavy dialect — CERCLA, NPL, SEMS — but the questions beneath it are plain.
A site appearing on this page means EPA has confirmed PFAS contamination at a National Priorities List Superfund site somewhere in Arizona. 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.
Federal Superfund sites in Arizona are managed by the EPA, with the Arizona Department of Environmental Quality (ADEQ) acting as the state-side partner. ADEQ helps oversee remediation and runs a state cleanup track for sites that don't reach the federal threshold.
Arizona has sites the federal EPA has placed on the National Priorities List for cleanup, reflecting the state's mining and manufacturing history. The table on this page shows what the public records currently hold; the Arizona Department of Environmental Quality partners with EPA on the cleanup.
ADEQ is the Arizona Department of Environmental Quality, the state agency that partners with the federal EPA on contaminated-site cleanup and oversees Arizona's broader environmental and remediation programs.
Our curated EPA dataset lists 8 PFAS-confirmed Superfund (NPL) sites in Arizona, including Hassayampa Landfill, Indian Bend Wash Area, Luke 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 Arizona 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.
