Is DHS going to adopt a drinking water standard for chromium 6?
DHS intends at this time to develop the nation s first drinking water standard for chromium 6. DHS has initiated the first step in this process by asking OEHHA to develop a PHG for chromium 6. The California Environmental Protection Agency, on behalf of OEHHA, has requested the University of California to form a scientific panel to provide guidance to OEHHA in establishing a chromium 6 PHG. At the same time, DHS has taken steps to obtain more information on the prevalence of chromium 6 in drinking water supplies. This information will enable DHS to develop data on cost and feasibility of treatment that must be considered as part of the development of a chromium 6 drinking water standard. In March 1999, DHS gave notice that it would be evaluating the total chromium drinking water standard to determine if the standard should be revised. After an initial review, DHS determined that there needed to be a better understanding of the distribution of chromium 3 and chromium 6 in drinking water
