Based on contaminant analyses from DNR, WQP, EPA ECHO, EPA UCMR5, 1 contaminant has been measured above federal EPA standards (MCL) and 1 exceeds health-based guidelines. The most significant finding is PFOS (Perfluorooctane Sulfonate) at 7.1 ng/L, which is 1.8x the EPA legal limit. Data is drawn from source-level compliance monitoring and covers 2001 through 2026. Results reflect conditions at the point of collection (wells, treatment plants), not necessarily at the tap.","data_period":{"start":"2001-08-29","end":"2026-12-31"},"contaminants_tested":43,"contaminants_detected":23,"exceedances":1,"guideline_exceedances":1,"contaminants":[{"name":"PFHpA
