Drinking water: PFAS testing
No public water system serving Idaho reported a PFAS detection in the UCMR5 national testing round. Systems serving under 3,300 people were only sampled in part, so absence from this table is not proof of absence in the water.

| Facility | City | Top chemicals | Total released |

Underground fuel tanks
EPA's UST Finder records 123 tank facilities in Idaho: 46 tanks in service and 290 closed. 30 fuel releases are on record, of which 1 remain open. Open releases are cleanups that have not reached "no further action".
Radon
EPA maps Idaho 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.
