Drinking Water

The Office of Environmental Health Hazard Assessment (OEHHA) within the
California Environmental Protection Agency is announcing the
availability of the revised draft technical support document for a
proposed Public Health Goal (PHG) for hexavalent chromium in drinking
water. This document decreases the proposed PHG to 0.02 parts per
billion, versus 0.06 ppb in the first draft posted in 2009; the change
is due to consideration of early-in-life exposures for cancer potency.
The draft document is posted on the OEHHA web site at www.oehha.ca.gov.
OEHHA is soliciting comments on the draft report during a 30-day comment
period. OEHHA follows the requirements set forth in Health and Safety
Code Sections 57003(a) and 116365 for receiving public input.
OEHHA will evaluate all the comments received and revise the document as
appropriate. Written comments must be received at the OEHHA address
below by 5:00 p.m. on January 31, 2010, to be considered before
publication of the final document. The final document will be posted on
the OEHHA web site along with responses to the major comments received
during the public review and scientific comment periods.
The PHG technical support documents provide information on the health
effects of contaminants in drinking water. The PHG is a level of
drinking water contaminant at which adverse health effects are not
expected to occur from a lifetime of exposure. The California Safe
Drinking Water Act of 1996 (codified at Health and Safety Code, section
116270 et. seq.), requires OEHHA to develop PHGs based exclusively on
public health considerations (Health and Safety Code section 116365(c)).
PHGs published by OEHHA are considered by the California Department of
Public Health in setting drinking water standards (Maximum Contaminant
Levels, or MCLs) as required by Health and Safety Code section 116365(a-b).
If you would like to receive further information on this announcement or
have questions, please contact our office at (510) 622-3170 or the
