American Water routinely tests its water supply for total chromium and all results have been in compliance with the USEPA standards. The following quote is taken from American Water’s website regarding chromium.
“At American Water, we take water quality and safety very seriously. The U.S. Environmental Protection Agency (USEPA) and state drinking water programs set water quality standards designed to protect public health and American Water treats your water to meet or surpass these standards, including those set for chromium.
The USEPA does not have specific drinking water regulations for chromium-6, only total chromium, which includes consideration of the health effects due to chromium-6. American Water routinely tests its water supply for total chromium and all results have been in compliance with the USEPA standards. We also voluntarily sample for chromium-6 in accordance with USEPA guidance.
American Water is supporting national research through the Water Research Foundation to better monitor and treat for chromium-6. The USEPA is also conducting a rigorous and comprehensive review of health effects of chromium-6. Our water quality experts are closely following this research and if necessary, will be ready to implement changes in our testing and treatment.
Water quality results on chrome-6 and other parameters can be found on American Water’s website http://amwater.com/water-quality-and-stewardship/payment-locations.html . Enter your zip code or city/state to get information on your specific water quality. There you will find the annual Consumer Confidence Report (CCR) and a basic water quality summary with links to additional information on chrome-6.”
