- Status
- ✓Not federally regulated
- Total chromium carries a federal MCL of 0.1 mg/L. Trivalent chromium alone does not, in the same way hexavalent chromium alone does not. Certifier listings routinely certify the two valencies as separate reduction claims, so they are separate registry entries.
- Pending change
- None recorded.
Settled. We re-check the federal register entry quarterly and stamp this panel with the date of the last check.
