Percholrate Risks Assesed
The draft risk estimate level is not a drinking water standard, but it is the first step in a lengthy process to determine if the agency should set a federal drinking water standard for this contaminant.
The efforts to characterize potential risks from perchlorate contamination and development of this revised external review draft have followed an open public process, highlighted by the working partnerhsip of the Interagency Perchlorate Steering Committee, which is co-chaired by the EPA and the U.S. Department of Defense, and which currently comprises representatives from more than 23 state, federal and tribal agencies.
After comments derived from the current public comment period are addressed, the final assessment document will undergo the agency's consensus clearance for inclusion on the EPA's Integrat-ed Risk Information System.
The draft assessment is available at the EPA's Internet site (www.epa.gov) under "What's New."
