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 test for Legionella bacteria in drinking water. Specifically, they must test a random sample of 0.1% of service lines quarterly and 1% of water system facilities (like treatment plants and storage tanks) monthly. Test results must be reported to the Department of Environmental Protection (DEP), and if contamination exceeds DEP-established standards, the system must notify customers and remediate within 30 days (with full resolution required within six months). Violations would be enforced under the state's Safe Drinking Water Act, potentially resulting in civil penalties.
