Screen a specific property in Illinois

County numbers set the context; a deal needs the registry around one address — registered tanks at the parcel, facilities within 500/1,500 ft, leak cleanups with status and distance, every line cited to the official record.

Screen an address — $49

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.
