PFAS-Confirmed Superfund Sites in New Hampshire

Superfund is a word that tightens the chest, so let's keep this plain and measured. The list below is a statewide screening view, not an address check, and a site somewhere in New Hampshire does not mean a particular home is affected. The state's record reflects a long history of light-to-moderate manufacturing alongside a notable military presence, which shapes what tends to show up here. Cleanup is a partnership: the federal EPA runs the national Superfund program, and the New Hampshire Department of Environmental Services (NHDES) is the state-side partner. Use this page to see what the public records show statewide, and treat a specific address as its own question worth reviewing.

Who manages contaminated-site cleanup in New Hampshire

In New Hampshire, contaminated-site cleanup is shared between the federal EPA and the New Hampshire Department of Environmental Services (NHDES), the state-side partner on Superfund that also runs its own waste-site remediation program. The NHDES helps oversee listed cleanups and tracks contaminated sites beyond the federal list. Consistent with its early posture on PFAS in drinking water, New Hampshire tends to be among the more active states in addressing PFAS at contaminated sites alongside the federal program. The steadying takeaway behind the word Superfund: a named, engaged state office is co-managing this work with EPA.

19 PFAS-confirmed Superfund sites in New Hampshire

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 New Hampshirelist does — and doesn't — tell you

If no PFAS-confirmed Superfund sites appear for New Hampshire, that is encouraging, but it is not a full all-clear. The NHDES and EPA track a far broader SEMS inventory than the PFAS-confirmed subset, so an empty result here mostly means this narrow category is quiet in the state, not that every site has been cleared. Treat it as a reassuring starting point rather than a final word, especially given the state's well-water dependence.

A site appearing on this page means EPA has confirmed PFAS contamination at a National Priorities List Superfund site somewhere in New Hampshire. 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 New Hampshire: common questions

Who oversees Superfund cleanup in New Hampshire?

Superfund cleanup in New Hampshire is co-managed by the federal EPA, which runs the national program, and the New Hampshire Department of Environmental Services (NHDES), which serves as the state-side partner and runs its own waste-site remediation work.

What is a Superfund site in New Hampshire?

A Superfund site is a location on the federal National Priorities List flagged for long-term cleanup. In New Hampshire, the New Hampshire Department of Environmental Services partners with EPA to oversee these sites, consistent with the state's active environmental posture.

What is NHDES?

The New Hampshire Department of Environmental Services, or NHDES, is the state agency that protects New Hampshire's water, land, and air and acts as the state-side partner to EPA on contaminated-site cleanup, including Superfund sites.

How many PFAS-confirmed Superfund sites are in New Hampshire?

Our curated EPA dataset lists 19 PFAS-confirmed Superfund (NPL) sites in New Hampshire, including Auburn Road Landfill, Beede Waste Oil, Chlor-Alkali Facility (Former). 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 New Hampshire 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 New Hampshire address?

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