Suggest adding as an external link "http://water.epa.gov/drink/info/chromium/guidance.cfm". this is the USEPA's page for hexavalent chromium in drinking water. the EWG article which precipitated much of the current concern would be found at; http://www.ewg.org/chromium6-in-tap-water.

Studies, Original Drinking MCL and Current Concerns

edit

When the USEPA was originally evaluating regulating the level of chromium in drinking water, it was assumed that via ingestion, and hexavalent chromium would be converted to trivalent chromium by stomach acids. Due to this the regulation was based upon trivalent chromium, which at higher concentrations has been shown to cause skin conditions. Based upon this data, the drinking water limit was set to 100 ug/L. More recently, concerns have arisen that individuals under medication reducing stomach acids would be particularly at risk to hexavalent chromium exposure.
