Drinking water: PFAS testing
No public water system serving Johnson 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.
Underground fuel tanks
EPA's UST Finder records 50 tank facilities in Johnson: 22 tanks in service and 104 closed. 33 fuel releases are on record, of which 18 remain open. Open releases are cleanups that have not reached "no further action".
Radon
EPA maps Johnson 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.
