|The Safe Drinking Water Act (SDWA), as amended in 1996, requires EPA, after consultation with the scientific community including the Science Advisory Board and opportunity for public comment, to publish a list every five years of currently unregulated contaminants that are known or anticipated to occur in public water systems and may require regulation under the SDWA (referred to as the Contaminant Candidate List, or CCL). This list is subsequently used to identify priority contaminants for further research needs and to make determinations on whether or not to regulate at least five contaminants from the CCL with national primary drinking water regulations (NPDWRs) (SDWA section 1412(b)(1)). EPA’s Office of Water has requested that the SAB Drinking Water Committee review the Draft Fourth Contaminant List (CCL4), which was released for public review and comment on February 4, 2015 (80 FR 6076). The draft CCL4 includes 100 chemicals or chemical groups and 12 microbial contaminants. |
