In their own words
HAWC
HAWC is a free web application for storing, displaying, and synthesizing data used in human health and environmental risk assessments. Its modules support study-quality evaluation, data extraction from human epidemiology, animal bioassay, and in vitro studies, evidence synthesis, and dose-response analysis. Assessment teams can assign managers, members, and reviewers role-based permissions for viewing, editing, and administration. Published material is viewable without an account, while collaboration on an ongoing assessment with EPA scientists requires a Login.gov account and approved EPA HAWC group access. Interactive visualizations connect studies, experiments, endpoints, and dose information. Users can download available datasets as Microsoft Excel files and export figures to PDF or other formats. Benchmark dose modeling is performed endpoint by endpoint at the EPA HAWC chemical manager’s discretion. HAWC supports most modern browsers, with Google Chrome preferred, and reports functionality errors with Internet Explorer.
