This bill introduces new regulations for public community water systems in New Jersey aimed at improving the safety and quality of drinking water, 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 responsible for developing best management practices to prevent pathogen growth and mandates that public community water systems create and implement maintenance plans. Additionally, any disruptions must be reported to the DEP within 72 hours, and a data management system will be established to track these incidents.

The bill also outlines the responsibilities of building owners and operators in managing water systems to reduce Legionella risks, especially in healthcare and residential facilities. It requires the development of water management programs that adhere to established standards and mandates periodic testing for Legionella bacteria. The Department of Health will oversee investigations of Legionnaires' disease cases and provide guidance for water management programs. The bill includes provisions for public notification, record-keeping, and establishes civil penalties for non-compliance, with fines ranging from $2,000 to $10,000. Furthermore, it directs the Department of Health, in collaboration with the DEP, to create a public awareness campaign about Legionella and requires annual reporting on Legionnaires' disease cases and water sampling results. The act is set to take effect immediately upon passage.
