870 community water systems on record — 373 active, 497 inactive.

Every active community water system nationwide must produce a Consumer Confidence Report under the EPA's revised rule, effective for reports due July 1, 2027.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Kentucky’s official records. Always confirm current status with Kentucky before making decisions based on this information.
