Requires water supply system testing and compliance with secondary drinking water regulations.

This bill requires public community water systems in New Jersey to test water quarterly for compliance with secondary drinking water standards (which cover non-health-related issues like taste, odor, and color). Systems must collect samples from at least 10% of customer taps and submit results quarterly to the Department of Environmental Protection, local municipalities, and customers. If tests exceed standards, systems must create a compliance plan within 30 days to fix issues within another 30 days. Additionally, systems must develop and submit a maintenance plan for ongoing compliance after corrections, with the department reviewing these plans within 30 days.
