HAWC Resources

EPA HAWC is an interactive, expert-driven, content management system for human health assessments that is intended to promote transparency, data usability, and understanding of the data and decisions supporting an environmental and human health assessment. Specifically, EPA HAWC is an application that allows the data and decisions supporting an assessment to be evaluated and managed in modules (e.g., study evaluation, summary study data) that can then be publicly accessed online.
