This bill introduces new regulations for public community water systems in New Jersey to enhance drinking water safety, particularly concerning Legionella bacteria. It defines "disruption of the public community water system" and requires owners or operators of systems with over 100 service connections to maintain specific disinfectant residual levels. The Department of Environmental Protection (DEP) is tasked with creating best management practices to prevent pathogen growth and mandates the development of a distribution system maintenance plan. The bill also emphasizes timely reporting of disruptions and the establishment of a data management system for tracking incidents.

Additionally, the bill requires certain buildings and facilities, such as hospitals and residential structures, to implement water management programs to reduce Legionella growth, adhering to recognized standards. The Department of Health will investigate reported cases of Legionnaires' disease and develop guidelines for these programs. It includes provisions for public notification during outbreaks and establishes penalties for non-compliance, ranging from $2,000 for first violations to $10,000 for serious infractions. The Department of Health is also tasked with assessing civil penalties, enforcing compliance, and raising public awareness about Legionella. The bill mandates annual reports to the Governor and Legislature on Legionnaires' disease cases and violations, while exempting residential properties with four or fewer units from its requirements.
