About this data
Water systems are matched to Hopkins County, nearest to St. Charles first. Your exact provider depends on your address and connection; the largest community water system in a county is usually the city or town utility.

The Kentucky records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
