Underground fuel tanks

EPA's UST Finder records 8,123 tank facilities in Harris: 6,276 tanks in service and 16,145 closed. 4,175 fuel releases are on record, of which 211 remain open. Open releases are cleanups that have not reached "no further action".

Radon

EPA maps Harris as Zone 3, the lowest predicted indoor radon (under 2 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.
