This document contains health risk information on regulated drinking water contaminants to assist public water systems in preparing these reports. A PHG is the concentration of a contaminant in drinking water that poses no significant health risk if consumed for a lifetime. PHGs are developed and published by OEHHA (Health and Safety Code Section 116365) using current risk assessment principles, practices and methods.

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.

OEHHA is announcing the release of a draft document for public review describing proposed Public Health Goals (PHGs) for the four regulated trihalomethanes (THMs) found in drinking water as a result of disinfection methods: chloroform, bromoform, bromodichloromethane and dibromochloromethane.
The technical support document, presents an update of the cis- and trans-1,2-DCE PHGs.
OEHHA is soliciting comments on the revised draft technical support document during a 30-day comment period. OEHHA will evaluate all the comments received and revise the document as appropriate.
