This document presents EPA's recommended Methodology for developing ambient water quality criteria as required under Section 304(a) of the Clean Water Act (CWA for States & Tribes' needs). The Methodology is guidance for scientific human health assessments used by EPA to develop, publish, & from time to time revise, recommended criteria for water quality accurately reflecting the latest scientific knowledge. Chapters: introduction to water quality criteria & standards & ambient water quality criteria (AWQC) methodology; clarifications on the methodology, risk characterization, & other issues for developing criteria; risk assessment; exposure; & references.

Section 304(a) (1) of the Clean Water Act 33 U.S.C. 1314(a) (1) requires the Environmental Protection Agency (EPA) to publish and periodically update ambient water quality criteria. These criteria are to accurately reflect the latest scientific knowledge (a) on the kind and extent of all identifiable effects on health and welfare including, but not limited to, plankton, fish shellfish, wildlife, plant life, shorelines, beaches, aesthetics, and recreation which may be expected from the presence of pollutants in any body of water including ground water; (b) on the concentration and dispersal of pollutants, or their byproducts, through biological, physical, and chemical processes; and (c) on the effects of pollutants on biological community diversity, productivity, and stability, including information on the factors affecting rates of eutrophication and organic and inorganic sedimentation for varying types of receiving waters. In a continuing effort to provide those who use EPA's water quality and human health criteria with up-to-date criteria values and associated information, the document was assembled. The document includes summaries of all the contaminants for which EPA has developed criteria recommendations.
