Find NJ contamination sites by address

A tool to find contamination sites by address in NJ

New Jersey’s environmental records are public, but the official tools — NJ-GeoWeb, the Contaminated Sites Explorer, DataMiner — still want a PI number, an exact facility name, or a buffer you draw yourself. This search starts with the address: type it the way you say it, pick the suggestion, and everything near that point comes back mapped — Known Contaminated Sites List cases (KCSL, sometimes written KCSNJ), registered UST facilities, groundwater restrictions, dry cleaners and gas stations, and NJDEP cleanup files for the property itself — with links into NJDEP DocMiner. Free — the address-first way to search contaminated sites by address in New Jersey instead of hunting the state maps record by record.

What one search checks

• NJDEP case files for this property — tank cases, spills, cleanups, including closed cases that no longer appear on contamination maps
• Known Contaminated Sites List — every reported soil or water contamination case within about a quarter mile, closest first, with the flags that matter: federal Superfund sites near the address, groundwater (CEA), deed notice, engineering controls
• Underground storage tank lookup — registered UST facilities within about 500 feet of the NJ address, with registration status and official tank files
• Deed notices and CEA groundwater restrictions by parcel — checked against the property itself, including mapped plume extents
• Immediate environmental concerns — vapor-intrusion and drinking-well cases nearby
• Dry cleaners, gas stations and autobody shops — the classic plume sources — plus PFAS discharge permits, chromate waste sites, brownfield areas, and regional groundwater monitoring wells
• Federal Superfund and hazardous-waste sites — EPA’s registry at the distances a Phase I environmental assessment uses: Superfund (NPL) within 1 mile, hazardous-waste treatment, storage or disposal within half a mile, large-quantity generators within a quarter mile
• Landfills — mapped solid-waste landfills and waste facilities within half a mile, and whether the lot itself sits inside a mapped landfill

Common questions

Is there a tool to find contamination sites by address in New Jersey?
Yes. Enter a street address above. The lookup checks NJDEP’s Known Contaminated Sites List, registered underground storage tanks, and site-remediation case files at that point and maps what is nearby.

How do I search the NJ Known Contaminated Sites List by address?
State maps let you search the KCSL by site name or Preferred ID. This tool geocodes the address and returns KCSL cases within about a quarter mile, closest first, with Superfund, CEA, and deed-notice flags.

Is this the same as NJ-GeoWeb or DataMiner?
Same public NJDEP layers. The difference is address-first instead of ID-first — plus tanks, closed cases, and document links in one pass.

Does a clean result mean the house has no heating-oil tank?
No. Most home heating-oil tanks are not in the state UST registry.

Honest limits

Ordinary home heating-oil tanks are mostly not in the state UST registry — a clean tank result here doesn’t rule one out on an older house. And a case near an address is context about the neighborhood, not a finding about that property: most cleanups are contained to the source site, and each record here says explicitly when contamination reached groundwater or produced a vapor or well impact. When a lookup layer doesn’t answer, the row says “Unavailable” — nothing is guessed.
