EPA's Risk-Screening Environmental Indicators (RSEI) model integrates data from multiple sources to help provide context to  toxic chemical waste management activities from a relative risk-based perspective. RSEI model results can help policy makers, researchers, and communities establish priorities for further investigation and to look at changes in potential health-related impacts over time.
