Requires water suppliers to reimburse residential customers for drinking water testing under certain circumstances.

This bill requires public water system operators in New Jersey to pay for drinking water testing at residential properties when contamination levels exceed federal or state standards. The reimbursement is triggered only when a municipal request is made and the testing is conducted by a laboratory certified by the Department of Environmental Protection. Additionally, the bill prohibits water utilities from passing these testing costs on to their regular ratepayers. The Department of Environmental Protection will be tasked with creating rules to implement these requirements.
