PFAS-Confirmed Superfund Sites in Delaware

The first thing to hold onto: this is a statewide screening list, not an address check. A Superfund site somewhere in Delaware says nothing definite about a specific home. As a small but historically industrial state, Delaware's cleanup history reflects a manufacturing and chemical-industry legacy concentrated in pockets — a statewide pattern, not a verdict on any one street. The Delaware Department of Natural Resources and Environmental Control (DNREC) serves as the state-side partner to the EPA's federal program. Use the list below to see what the public records show across the state, and treat an address-level review as the sensible next step worth reviewing for a particular property.

Who manages contaminated-site cleanup in Delaware

On cleanup, Delaware's state-side partner to the EPA is the Delaware Department of Natural Resources and Environmental Control (DNREC). Working alongside the federal Superfund (NPL) program, DNREC co-manages remediation and typically runs a state-level site-investigation and cleanup program for contaminated properties that don't reach the federal list. For PFAS at contaminated sites, the state tends to operate within the federal framework rather than a separate enforceable standard. The takeaway is orientation, not dread: there's a named state office on this.

7 PFAS-confirmed Superfund sites in Delaware

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 Delawarelist does — and doesn't — tell you

A statewide Superfund list orients you; it doesn't deliver a verdict on a single home, and DNREC's remediation role is part of why these sites are documented and monitored. Four considerations help. Distance first — being in the same state as a site is far less meaningful than being near one. Then the contamination type and whether it can travel through soil, air, or groundwater. Then the cleanup stage, because many listed sites are already in active remediation. And finally, where the home in question actually gets its water. The federal alphabet — NPL, CERCLA, SEMS — is its own dialect, so a translation now and then is only fair. Should Delaware's PFAS-confirmed list come back empty, note it but don't read it as a full all-clear: it covers confirmed PFAS only, while DNREC's wider site inventory and the EPA's SEMS records may still track other concerns.

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

Who oversees Superfund cleanup in Delaware?

Superfund (NPL) sites are federal, administered by the EPA, with the Delaware Department of Natural Resources and Environmental Control (DNREC) as the state-side partner. DNREC co-manages cleanup and runs its own site-investigation and remediation program for properties that fall below the federal list.

How do I find Superfund sites in Delaware?

The list below shows EPA National Priorities List sites recorded statewide for Delaware. It's a statewide screening view, not an address check — a site somewhere in the state doesn't mean a specific home is affected. DNREC and the EPA maintain the cleanup records.

What is a Superfund site?

A Superfund site is a contaminated location the EPA addresses under the federal CERCLA program, with the most serious listed on the National Priorities List (NPL). In Delaware, the EPA and DNREC jointly track and manage that cleanup work.

How many PFAS-confirmed Superfund sites are in Delaware?

Our curated EPA dataset lists 7 PFAS-confirmed Superfund (NPL) sites in Delaware, including Army Creek Landfill, Blades Groundwater, Delaware Sand & Gravel Landfill. 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 Delaware 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 Delaware address?

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