Impact/Purpose:
To inform the public.
Description:
The Causal Analysis/Diagnosis Decision Information System, CADDIS, is an online system that uses a step-by-step guide, worksheets and examples to help scientists and engineers find, access, organize, share and use environmental information to evaluate causes of biological effects in aquatic ecosystems. It is based on EPA's Stressor Identification (SI) Guidance, which provides a formal, rigorous process to identify stressors causing biological impairments in aquatic ecosystems including a structure for organizing the scientific evidence. CADDIS implements the SI process, but also contains updates, clarifications and additional material developed since the SI document was published in 2000. As the project continues CADDIS will incorporate ORD's research results relevant to causal analysis.
