TRENTON, N.J. (AP) — New Jersey’s Senate has passed a bill that would require water systems to notify residents about elevated lead levels within 10 days, down from 60. It’s the latest development concerning lead in the water since Newark reported elevated drinking water levels in just a handful of samples. The city has since begun replacing the lead pipes that connect water mains to homes, as have other cities. New Jersey has 582 water systems that serve towns. The state Democrat-led Senate passed the measure Monday. Now the bill goes to the Assembly.
