This analysis of a representative residential water sample was conducted in response to public concern related to possible exposure to hexavalent chromium via drinking water, and to the draft regulation recently proposed by the California Department of Health Services that would add hexavalent chromium to the list of unregulated chemicals for which monitoring would be required in vulnerable drinking water sources. This treatise also addresses the issues of adequacy of the current maximum contaminant limit standard for total chromium (50 part per billion) and the necessity of establishing a separate maximum contaminant limit standard for hexavalent chromium.
