Substance found at levels well below national drinking water standard.

WASHINGTON (September 20, 2016) – The Environmental Working Group released a report today about the presence of hexavalent chromium in drinking water. In response to this development, the American Chemistry Council released the following statement:

“The Environmental Working Group (EWG) report does not provide any new information about hexavalent chromium in the water supply. In its third monitoring program (2012-2016), the U.S. Environmental Protection Agency (EPA) monitored both total chromium and hexavalent chromium in drinking water supplies around the country under its Unregulated Contaminant Monitoring Rule (UCMR). Throughout this process, EPA made these data available on its website. This is the data that is now being used in the EWG report. 

“EPA’s data show that when hexavalent chromium is found in the ground water, it’s present at low levels that are well below the national drinking water standard set by EPA. EPA and U.S. Geological Survey attribute these low levels to geologic formations, such as rocks.

“Because of the limited scientific data available to inform how low environmental levels of this naturally-occurring substance could impact human health, ACC supported a third party research organization to undertake a large, multiple-institution research study. Some of the papers received awards from the preeminent Society of Toxicology.

“This is a positive example of industry supporting independent, peer-reviewed research to inform regulatory decisions about hexavalent chromium and drinking water.

“ACC believes EPA’s Integrated Risk Information System (IRIS) program, and other government agencies, should consider the entire scientific database on hexavalent chromium as it makes regulatory decisions about this substance. EPA is currently drafting its IRIS Assessment.”
