Comment period on the Initiation of PHG reviews for four chemicals: Cis-1,2-Dichloroethylene, Trans-1,2-Dichloroethylene, Hexavalent Chromium and Nickel
Water
OEHHA performs major risk assessment and hazard evaluation activities relating to chemical contaminants in drinking water. These activities include developing health advisories, Public Health Goals for chemical substances in drinking water, Notification Levels, and providing toxicological assistance for chemical monitoring activities for the drinking water supply. The program also provides education to the public and other governmental agencies on drinking water contamination and drinking water regulatory standards development.

Includes changes in critical study and endpoint selection, and updated dose-response analysis and exposure estimates. These changes resulted in the revision of the antimony PHG to 1 ppb.
The updated PHGs are 0.7 parts per billion (ppb) for carbofuran, 6 ppb for diquat, 0.3 ppb for endrin, 166 ppb for picloram, and 42 ppb for thiobencarb, all based on non-cancer effects.
2nd public comment period proposed updated PHGs for Carbofuran (0.7 ppb), Diquat (6 ppb), Endrin (0.3 ppb), Picloram (166 ppb), and Thiobencarb (42 ppb) in drinking water.
Written comments for the proposed updates of Public Health Goals (PHGs) for carbofuran, diquat, endrin, picloram, and thiobencarb in drinking water must be received by the PHG program by 5:00 p.m. on August 29, 2016.
2nd public comment period on the draft Public Health Goal (PHG) for antimony in drinking water. The draft PHG would revise the PHG from 20 ppb to 1 ppb.
Announcement of the second public comment period on the draft Public Health Goal (PHG) for antimony in drinking water. The draft PHG would revise the PHG from 20 ppb to 1 ppb.
