Violation History
See every time your water exceeded legal limits or missed required testing — up to 10 years back.
Recommendations
Get specific, actionable suggestions — whether that's a filter type, a test kit, or nothing at all.
About this data: ClearWater uses the EPA's Safe Drinking Water Information System (SDWIS). Data is for public water systems only — private wells are not included. Legal limits (MCLs) are minimum standards; some contaminants may still pose health risks below legal thresholds.
