DetectedIndustrial contaminant. Known human carcinogen. Unregulated at the federal level in the US.
EWG flags chromium-6 as a California watch contaminant in Sacramento area reporting.

Low-level arsenic monitoring appears in regional groundwater influenced sources.
Trihalomethanes (THMs)

The figures above reflect utility-wide averages from the most recent public report. If you have specific health concerns, request a full report from your utility or test your own tap water.
