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 sample of at least 0.1% of service lines every three months and a random sample of at least 1% of water system facilities (like storage tanks and treatment plants) each month. If Legionella levels exceed the standard set by the Department of Environmental Protection, the system must immediately notify affected customers and complete remediation within six months. All testing must follow DEP-approved best practices and be conducted by accredited labs, with results reported to the department.
