California’s New Hexavalent Chromium MCL: How BSK Associates Supports Your Water System Compliance

Hexavalent Chromium Testing in California.  If you manage a California public water system, you’re facing a significant new compliance challenge that could impact your operations, budget, and community’s trust.

Starting October 1, 2024, California established a maximum contaminant level (MCL) of 10 µg/L (10 ppb) for hexavalent chromium in drinking water—a standard adopted with primary emphasis on protecting public health. Scientific evidence shows that long-term ingestion of hexavalent chromium increases cancer risk, making this regulation critical for the communities you serve.

Here’s What This Means for You:

• Large systems (10,000+ connections)must begin compliance monitoring by October 1, 2026
• Medium systems (1,000–9,999 connections)must comply by October 1, 2027
• Smaller systems face later deadlines but still need to prepare

As these deadlines approach, you’re likely asking yourself:

• How do I ensure accurate, timely testing to meet regulatory reporting schedules?
• What if lab capacity constraints delay my results and put me out of compliance?
• How do I navigate routine monitoring, confirmation sampling, and treatment performance verification without overwhelming my team?

You’re not alone in feeling this pressure. Meeting the State’s monitoring requirements can feel daunting—especially when you’re already managing day-to-day operations and serving your community’s essential water needs.
