Fact Sheet: Draft Human Health Recreational Ambient Water Quality Criteria/Swimming Advisories for Microcystins and Cylindrospermopsin
EPA has issued for public comment draft Human Health Recreational Ambient Water Quality Criteria (AWQC) and/or Swimming Advisories for Microcystins and Cylindrospermopsin. These are the draft recommended concentrations of microcystins
and cylindrospermopsin in recreational water at or below people will be protected while swimming or participating in other activities on the water.
EPA will accept comments on the 2016 draft criteria document for 60 days. Once final, states can consider adopting these criteria into their water quality standards and using them for Clean Water Act purposes, once the standards are approved by EPA. Alternatively, states can use these same values as the basis of swimming advisories for public notification purposes at beaches.
