Bill Summary · S 4634

Legislative bill overview

S 4634 mandates that New Jersey's Department of Environmental Protection (DEP) establish a maximum contaminant level (MCL) standard for hexavalent chromium in drinking water. Hexavalent chromium is a toxic form of chromium linked to cancer and other health effects. The bill would create enforceable state-level drinking water quality standards for this chemical.

Why is this important

Hexavalent chromium contamination has been documented in drinking water systems across New Jersey and nationally, posing documented public health risks. Currently, New Jersey lacks its own MCL standard for hexavalent chromium, leaving regulation to federal EPA standards, which some argue are insufficient. Establishing a state standard could provide more stringent protections and ensure water suppliers take targeted action to reduce contamination.

Potential points of contention

  • Compliance costs: Water utilities may face significant expenses to test for and remove hexavalent chromium, potentially increasing consumer water bills
  • Standard stringency: Debate over whether the MCL should match federal EPA levels or be stricter, affecting feasibility and cost-benefit calculations
  • Implementation timeline: Unclear deadlines for DEP rulemaking and utility compliance could create regulatory uncertainty or rushed standards
