California Proposes Regulations on Hexavalent Chromium in Drinking Water
The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is announcing the availability of draft technical support document for the proposed Public Health Goal (PHG) for hexavalent chromium in drinking water. This draft document is a new risk assessment, culminating an extensive evaluation of oral toxicity of this chemical. A PHG of 0.06 ug/L or 0.06 parts per billion (ppb) is proposed for hexavalent chromium in drinking water, based on tumor incidence data from rodent cancer bioassays. OEHHA is soliciting comments on the draft report during a 45-day comment period. The Office will also hold a public workshop on October 19, 2009 at the Elihu Harris Building, 1515 Clay Street, Oakland, 94612, Room 1, 10 a.m.-12 noon, or until business is concluded. OEHHA follows the requirements set forth in Health and Safety Code Sections 57003(a) and 116365 for conducting the workshop and receiving public input.
