September 18, 2017 workshop on the draft technical support document for the update of the Public Health Goals (PHGs) for cis-1,2-dichloroethylene (cis-1,2-DCE) and trans-1,2-dichloroethylene (trans-1,2-DCE) in drinking water.
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.

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is announcing the availability of the draft technical support document for the update
Draft technical support document for the update of the Public Health Goals (PHGs) for cis-1,2-dichloroethylene (cis-1,2-DCE) and trans-1,2-dichloroethylene (trans-1,2-DCE) in drinking water. The document proposes an updated PHG of 13 parts per billion (ppb) for cis-1,2-DCE and 50 ppb for trans-1,2-DCE.
Comment period on the proposed update of the PHGs for nitrate and nitrite published in 1997. OEHHA is proposing to retain the original PHG values.
The workshop is provided to enable a dialogue between OEHHA scientists and the public to discuss the scientific basis of the proposed PHG updates, and to receive comments.
