Guidance for Reviewing Pesticide Environmental Fate Studies

EPA's pesticide program reviews subject studies in support of drinking water exposure and ecological risk assessments. The two guidance documents provide study review guides and a report guide to help our scientists uniformly consider issues, data, and formatting relevant to efficiently review environmental fate studies.
