This bill requires the Department of Environmental Protection (DEP), the Department of Health (DOH), and operators of public water systems and certain buildings to implement measures to prevent and control Legionnaires' disease. Key provisions include maintaining a minimum detectable disinfectant residual of free chlorine of at least 0.3 milligrams per liter, conducting regular testing, and notifying customers of any disruptions in the water distribution system that could lead to increased Legionella bacteria levels. The DEP is responsible for creating a publicly accessible database of these disruptions and developing guidelines for notification. Additionally, the bill outlines penalties for non-compliance and mandates the implementation of water management programs in specific buildings, particularly healthcare facilities.

The DOH is tasked with investigating every reported case of Legionnaires' disease and providing information on testing for affected individuals. The bill establishes a registry of de-identified data related to Legionnaires' cases and emphasizes collaboration among state agencies. It also mandates the development of a public awareness campaign to educate consumers about the risks associated with Legionella and necessary precautions. Furthermore, the DOH, in collaboration with the DEP and other agencies, is directed to adopt regulations and prepare an annual report on Legionnaires' disease cases and recommendations for further legislative action.
