Drinking water: PFAS testing

No public water system serving Kauai 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.

3 facilities in Kauai filed TRI reports for 2024, totalling 18k lb released.

Underground fuel tanks

EPA's UST Finder records 199 tank facilities in Kauai: 102 tanks in service and 353 closed. 90 fuel releases are on record, of which 6 remain open. Open releases are cleanups that have not reached "no further action".

Radon

EPA maps Kauai 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.
