EPA Requests Scientific Views on Ambient Water Quality Criteria Document for Chloroform

The U.S. Environmental Protection Agency (EPA) has requested scientific views on a revised draft human health criteria document for chloroform.

The Agency derived the revised criteria according to the procedures and methods in EPA's Methodology for Deriving Ambient Water Quality Criteria for the Protection of Human Health (2000) (2000 Human Health Methodology).

The Clean Water Act (CWA) requires the EPA to develop and publish and, from time to time, revise criteria for water accurately reflecting the latest scientific knowledge. When final, these criteria will provide EPA's recommendations to States and authorized Tribes as they establish their water quality standards as State or Tribal law or regulation.

At this time the Agency is not making final recommendations. Rather, EPA's requesting scientific views on the draft revised criteria because the criteria reflect changes in several of the values used to derive them, including the Reference Dose (RfD), the Relative Source Contribution (RSC) and Bioaccumulation Factors.

All scientific information must be submitted to the Agency on or before March 22, 2004.

Scientific views may be submitted electronically, by mail, or through hand-delivery/courier. Copies of the criteria document entitled, Ambient Water Quality Criteria for the Protection of Human Health: Chloroform--Revised Draft (EPA-822-R-04-002) may be obtained from EPA's Water Resource Center by phone at (202) 566-1729, by e-mail to [email protected] or by conventional mail to EPA Water Resource Center, 4101T, 1200 Pennsylvania Avenue NW., Washington, DC 20460.
