Drinking water: PFAS testing
No public water system serving Mackinac 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 126 tank facilities in Mackinac: 58 tanks in service and 324 closed. 76 fuel releases are on record, of which 32 remain open. Open releases are cleanups that have not reached "no further action".
Radon
EPA maps Mackinac 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
