How to test for and remove Chromium 6, AKA Hexavalent Chromium

A recent study by the environmental working group established that hexavalent chromium is in the drinking water supplies of many major cities, including places like Honolulu where you would not expect contamination from industrial processes. Chromium 6 (or Chromium VI) is found in concentrations averaging over 3 times the safe legal limit overall, which means that it is not being adequately filtered from municipal water supplies.

What is the minimum safe level for hexavalent chromium? The EPA standard is 100 parts per billion, but the State of California calculates that .02 parts per billion is a more realistic standard. It has been associated with gastrointestinal tumors, liver and kidney damage, and stomach cancer. For people with higher levels of Chromium 6 in their water, a reverse osmosis drinking water filter will reduce hexavalent chromium, but such filters do not filter water from showering, bathing, and hand washing.

Notes and Special Information

Special note: There are some voices in the scientific community who believe the concerns about Chromium 6 may be overly alarmist, so it pays to study both sides and consider how much of a chemical is bad for human health.
