Underground fuel tanks

EPA's UST Finder records 832 tank facilities in San Bernardino: 2,368 tanks in service and 30 closed. 1,081 fuel releases are on record, of which 43 remain open. Open releases are cleanups that have not reached "no further action".

Radon

EPA maps San Bernardino as Zone 2, moderate predicted indoor radon (2 to 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.
