EPA publishes its fourth Draft Contaminant Candidate List
To ensure continued protection of public health, the U.S. Environmental Protection Agency (EPA) has published for public review and comment a draft list of contaminants that are not currently regulated in drinking water, but may require regulations in the future under the Safe Drinking Water Act (SDWA). The agency will evaluate and consider the public comments on developing the final Draft Contaminant Candidate List (CCL 4) and suggestions for improvements to the process for future CCLs.
Inclusion of contaminants on the CCL is one tool the agency uses to identify contaminants for regulatory decision making and research needs. The Draft CCL 4 includes 100 chemicals or chemical groups and 12 microbiological contaminants. The list includes, among others, chemicals used in commerce, pesticides, biological toxins, disinfection byproducts, pharmaceuticals and waterborne pathogens.
Contaminants on the CCL are known or anticipated to occur in public water systems at levels of potential concern for public health. The SDWA requires EPA to publish a CCL every five years.
