Summary

The US Environmental Protection Agency (EPA) is required by the Clean Water Act to publish and update ambient water quality criteria, which reflect the latest scientific knowledge on the effects of pollutants on health and welfare, including aquatic life and human health. These criteria are not regulatory rules but provide scientific data and guidance for deriving regulatory requirements. The EPA has issued various publications on water quality criteria since 1968, including the "Green Book," "Blue Book," and "Red Book." The agency has also published individual criteria documents for pollutants listed as toxic under the Clean Water Act. The "Quality Criteria for Water 1986" document summarizes the criteria recommendations for contaminants and provides information on the development and publication of ambient water quality criteria. The EPA plans to publish about 10 final criteria documents each year, updating and revising existing criteria and issuing new ones. The agency also develops Acceptable Daily Intake (ADI) or Verified Reference Dose (RfD) values for chemicals, which have resulted in significant changes to the values used in human health criteria calculations for certain chemicals, including cyanide, ethylbenzene, nitrobenzene, phenol, and toluene.
