To help meet the U.S. Environmental Protection Agency (EPA) Superfund program's mandate to protect human health and the environment from current and potential threats posed by uncontrolled hazardous substance (both radiological and non-radiological), pollutant, or contaminant releases, the Superfund program has developed an ecological risk assessment process as part of its remedial response program. This webinar will describe the process and results from a research project concerning factors that could potentially attribute to adverse ecological risk for biota due to radioactive contamination in soil or water at or near Superfund sites. This project reviewed models and guidance on assessing protection of biota to exposures from contamination at sites issued or recommended by federal, state, and foreign governments.

Gregory Latronica is a recent graduate of Georgetown University with a B.S. in Environmental Biology. He has a strong passion for sustainability, conservation, and science, and has a variety of laboratory and field research experience. This past year he worked as an intern exploring ecological risk assessment models for biota protection to improve the EPA's Benchmarks for Superfund sites under the guidance of Stuart Walker and Michele Burgess. This opportunity was made possible through the U.S. Department of State's Virtual Student Federal Service program.

Stuart Walker has been employed by U.S. EPA in Washington, DC since 1990 in either the Superfund program (the Office of Superfund Remediation and Technology Innovation) or the Office of Radiation and Indoor Air working on issues regarding the cleanup of contaminated sites. His primary area of responsibility includes serving as the Superfund program's national lead on issues regarding radioactively contaminated CERCLA sites. In this role, Stuart develops national policy for risk assessment including models, community involvement, compliance with Applicable or Relevant and Appropriate requirements (ARARs), establishing cleanup levels and management of radioactive contamination at CERCLA sites.
