Abt has conducted quantitative risk assessments to support environmental policy and regulatory decisions in the U.S. and overseas for more than two decades.
We have conducted many ecological risk assessments for the Environmental Protection Agency. For example, EPA drew on Abt’s work to set national air quality standards, establish site-specific waste clean-up goals, and specify effluent guidelines for particular industries or limits for particular water bodies.
Our work has also included creating the Risk Screening Environmental Indicators (RSEI) model. The RSEI model combines data from numerous sources—including meteorological data, chemical toxicity, and physiochemical properties—to allow policy makers and the public to examine the potential impact of chemical emissions on both human health and ecological endpoints.
We also developed new ecological benefits methods that characterize the societal value of ecological endpoints—whether or not such benefits can be explicitly monetized.
