Requires DEP to establish maximum contaminant level for hexavalent chromium in drinking water.

This bill requires New Jersey's Department of Environmental Protection (DEP) to set a legal limit of 10 parts per billion for hexavalent chromium (a toxic form of chromium) in drinking water. It affects all public water systems, with deadlines based on system size: larger systems (10,000+ connections) must comply within 2 years, medium systems (1,000-9,999 connections) within 3 years, and smaller systems (under 1,000 connections) within 4 years after the law takes effect. The bill does not change existing limits for total chromium but specifically restricts hexavalent chromium to the new 10 ppb standard. The DEP may later adopt stricter limits if recommended by the Drinking Water Quality Institute.
