Chromium and Chromium 6 (hexavalent chromium)
In 2000, there was significant interest in the detection and possible health effects of chromium 6 in drinking water supplies throughout the state. In 2001, the California Office of Environmental Health Hazard Assessment (OEHHA) withdrew their previously established a Public Health Goal (risk assessment level) of 2.5 parts per billion for total chromium. The current Maximum Contaminant Level enforced by the California Department of Health Services Drinking Water Program (DHS) is 50 parts per billion for total chromium, and OEEHA is in the process of establishing a specific Public Health Goal for chromium 6. Southern California Water Company initiated sampling of all of it's sources for total chromium in 2001.
