Requires owners of certain buildings to test drinking water for Legionella bacteria.

This bill requires owners of specific buildings - including hospitals, nursing homes, assisted living facilities, public housing, and correctional facilities - to test drinking water annually for Legionella bacteria. Owners must use Department of Environmental Protection (DEP)-approved methods and labs, report results to the DEP, and notify residents if levels exceed DEP-set standards. If contamination is found, owners must begin remediation within 30 days and complete it within six months, followed by retesting to confirm safety. The law aims to prevent Legionnaires' disease outbreaks by ensuring regular water safety checks in high-risk facilities.
