EPA Seeks Recommendations for Sixth Candidate Contaminant List
On February 17, EPA published a request for nominations for the Sixth Contaminant Candidate List (CCL 6). Interested parties can nominate any chemicals, microbes, or other substances that are not currently regulated in drinking water. The CCL is a list of drinking water contaminants that are known or anticipated to occur in public water systems and may require future regulation. EPA uses the CCL to prioritize research and data collection efforts to help the agency determine whether to regulate a specific contaminant. EPA is required under the Safe Drinking Water Act to publish the CCL every five years. In the future, the Agency will publish a draft CCL 6 and provide the public opportunity to comment. Additionally, EPA will consult with the scientific community, including the Science Advisory Board. The public has until April 18 to submit nominations.
