Find buried fuel tanks and old leaks before you buy a property
Gas stations, repair shops, and many older homes have fuel tanks buried underground. When a tank leaks, the cleanup can cost more than the building — and once you buy the property, the problem is yours. We check your address against EPA's national tank registry and give you the answer in ten seconds. Every line links to the official government record.

You get: every registered tank at the property · every tank site within 1,500 feet · every known fuel leak nearby, and whether its cleanup is finished · a permanent link and a clean PDF.
Environmental firms charge about $2,500 to assess a site. This $49 screen tells you in ten seconds whether you need to spend that money.

This is a screen of EPA-registered tank and leak records, not an environmental site assessment. State registries are incomplete by design: tanks removed before 1986 and most residential heating-oil tanks were never registered, so a clean screen cannot prove the absence of a tank. "Closed" means a tank was taken out of service per the registry — it does not certify that no contamination remains.
The Northeast: where the registry has the most to say
Older buildings, oil heat, and a century of gas stations — these counties carry the densest tank history in the country.

Who uses this
- Home buyers — a vent pipe in the flower bed, or a house that once heated with oil, can mean a forgotten tank. Find out what's on record before your inspection deadline passes.
- Commercial buyers and their brokers — know a listing's tank history before the buyer's bank finds it for you.
- SBA lenders and loan officers — loans on gas stations and dry cleaners require an environmental check. The screen is the ten-second first look, and the commercial version includes a prep sheet your borrower's consultant can start from.
