Underground fuel tanks

EPA's UST Finder records 408 tank facilities in Washington: 160 tanks in service and 1,116 closed. 260 fuel releases are on record, of which 31 remain open. Open releases are cleanups that have not reached "no further action".

Radon

EPA maps Washington as Zone 1, the highest predicted indoor radon levels (over 4 pCi/L average). Radon and air quality are covered in depth on lung.com.

The record for one specific address

County figures blur what matters: distance. The Address Environmental Report runs these same federal datasets against one address and reports every site, tank, polluter and water result around it, with distances, in about a minute.
