Lead Pipe Data by Area — Kentucky

Lead pipe replacement law in Kentucky

Kentucky has not set its own state-specific lead service line replacement deadline beyond the federal requirement below. The rule is implemented through the Kentucky Division of Water, which required every public water system to submit a baseline inventory by October 16, 2024 as part of the federal Lead and Copper Rule Revisions, rather than setting an earlier state-specific replacement date.

Separately from any state law, the EPA's federal Lead and Copper Rule Improvements require every water system nationwide to submit a baseline inventory and an approved replacement plan by November 1, 2027, then fully replace all lead and "galvanized requiring replacement" lines under its control on a schedule of 10 years or less from that date, replacing at least 10% of its known lead/GRR lines per year. A narrow exception allows a longer schedule only for the roughly 1% of systems with an unusually dense concentration of lead lines, and partial (non-emergency) replacements are prohibited.
