Requires owners or operators of public community water systems to perform certain tests for Legionella bacteria.

This bill requires owners or operators of public community water systems in New Jersey to regularly test drinking water for Legionella bacteria. Specifically, they must test a random 0.1% sample of service lines every three months and a random 1% sample of water system facilities (like storage tanks and treatment plants) monthly. Test results must be reported to the Department of Environmental Protection (DEP), and if Legionella levels exceed DEP-established standards, systems must notify affected customers and remediate within 30 days (completing remediation within six months). The DEP will develop testing best practices and safety standards to guide implementation.
