Ecological Risk Assessment

ASA uses and develops computer models that evaluate the transport, fate, and biological effects of oil, chemicals, and other foreign matter in marine and fresh water environments. ASA scientists apply these models to spills or long-term discharges. Models hindcast or forecast single scenarios or provide probability distributions of impacts. ASA combines these sophisticated tools with comprehensive field programs and data collection to provide site-specific impact and ecological risk assessments.

By performing reverse trajectory calculations from sensitive sites such as water intakes or fragile wetlands, we can identify probable release locations of spills and principal avenues of vulnerability for these important resources. Results can be used to determine the probability of oiling sensitive resources.
