EPA Establishes Process to Evaluate Arsenic in Drinking Water Standard:
Last week EPA established a process for setting a new standard for arsenic in drinking water. The National Academy of Sciences (NAS) will perform an expedited review of EPA's risk analysis for arsenic, focusing on levels ranging from three to 20 parts per billion. NAS will also review new studies regarding the health risks of arsenic ingestion. Additionally, EPA will convene a subgroup of the National Drinking Water Advisory Council to assess the economic issues associated with the standard. In order to allow time for these reviews, EPA has proposed to extend the effective date for a new
arsenic standard an additional 9 months, from the current May 22 effective date until February 22, 2002. The compliance date for the new standard will remain until 2006. For more information on the proposal, go to www.epa.gov/safewater/arsenic.html on the Internet.
