AN ACT CONCERNING THE DISCLOSURE OF WATER QUALITY TEST RESULTS FOR CERTAIN PRIVATE AND SEMIPUBLIC WELLS.

HB 5167 requires laboratories testing private residential wells and semipublic wells (like those serving schools or community centers) to report water quality results to local health authorities and the state Department of Public Health within 30 days of testing. It removes the previous requirement for the Commissioner of Public Health to approve disclosures, allowing direct sharing of results with well owners, adjacent property owners, and prospective buyers who have signed purchase contracts. The bill takes effect October 1, 2026, and applies to all such wells in Connecticut. This change streamlines access to water quality information for affected property owners and buyers without altering confidentiality protections for other uses.
