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 for Legionella bacteria in drinking water. Specifically, they must test a random 0.1% sample of service lines quarterly and a random 1% sample of water system facilities (like storage tanks and pipes) monthly, using Department of Environmental Protection (DEP)-approved methods. If tests show excessive Legionella levels, they must notify affected customers within 24 hours and remediate the issue within 6 months. Violations would be treated as breaches of the Safe Drinking Water Act, potentially leading to administrative penalties.
