Hexavalent Chromium – Water Toxicity

Hexavalent Chromium – Water Toxicity

Steps to take to remove this carcinogen from your water supply


What steps do you recommend people take if they’re concerned about toxins in their drinking water? (or any other source of chemical contamination at home)

Recently it was shown by the EWG ( that Hexavalent Chromium (Chromium-6 or Chrom-6) is, a known carcinogen is still detectable well above the limits set by California’s Environmental Protection Agency (CalEPA) CalEPA recommends no more than 0.02 ppb (parts per billion). Based upon the findings, the average person level of worry should be based upon local water quality findings.


If you live in an area that is significantly higher than CalEPA’s recommended upper limit of 0.02ppb, you should take immediate steps to reduce your exposure. However, these are best practices for all areas where chromium-6 levels are detected.

(1) Stop consuming (drinking, oral hygiene) and cooking with this water.

(2) Install a system that will remove chromium-6 from your entire house OR at least your kitchen sink. Reverse osmosis is the most widely available that will remove chromium-6 from water. Make sure that you are installing a system that is certified to remove this carcinogen from your water.

(3) If you cannot afford a system that will remove chromium, find alternative clean sources of water (spring or bottled).


These water quality steps are particularly important for those who are cancer survivors and those that have a family history of any type of cancer. However, the lack of a family history does not mean that you cannot get cancer from chromium-6. This is why it is classified as a known human carcinogen.
