This bill mandates that public community water systems in New Jersey conduct quarterly sampling and testing of their water supply to ensure compliance with secondary drinking water regulations as established by the Department of Environmental Protection (DEP). The testing protocols will require sampling from at least 10 percent of customer taps, in addition to testing when the water enters the distribution system. The bill also stipulates that the owner or operator of the water system must submit quarterly and annual test results to the DEP, local governing bodies, and customers. If test results exceed the established standards, the water system must develop a compliance plan within 30 days to rectify the issue.

Additionally, the bill requires the public community water system to create and submit a maintenance plan for DEP approval, ensuring ongoing compliance with secondary drinking water regulations after the initial compliance is achieved. The DEP has specific timelines for approving or disapproving these plans, and if no action is taken within 90 days, the maintenance plan will be automatically approved. The bill aims to enhance the safety and quality of drinking water in New Jersey by enforcing stricter testing and compliance measures.
