EPA Publishes a New List of Contaminants for Potential Regulation under the Drinking Water Program

EPA has published a draft list of contaminants that are currently not subject to any proposed or promulgated national primary drinking water regulations. These contaminants are known or anticipated to occur in public water systems and may require regulation under the Safe Drinking Water Act. This draft list is the fourth Contaminant Candidate List (CCL 4) published by the agency since 1996. This Draft CCL 4 includes 100 chemicals or chemical groups and 12 microbial contaminants.  The list is appended to this issue as Attachment 2.
