Abstract: | In the early 1990s, U.S. Environmental Protection Agency Region 9 developed a training workshop for environmental professionals. It was successfully taught throughout Region 9 in collaboration with the California Department of Toxic Substances Control. We have updated the workshop's manual to incorporate current practices including: vapor intrusion into indoor air, benchmark dose, cancer guidelines, inhalation guidance, ecological and screening risk assessments, conceptual site models, and data quality objectives. We maintained the popular workshop format, with participants evaluating information and drawing conclusions in an interactive hands-on approach. We kept the case study approach to simulate realistic environmental issues. After a case study introduction, participants plan a sampling strategy. Principles of toxicology are introduced, and participants develop toxicity criteria using hypothetical animal study results. Participants then identify exposure pathways, and calculate exposure and risk and hazard estimates. Finally, participants develop remedial alternatives and practice risk communication through role playing exercises. The workshop has been an effective tool for training new employees and providing continuing education for experienced employees from consulting, military, and regulatory agencies. The format provides a dynamic learning environment, fostering exchanges among professionals with a wide range of skills and backgrounds (project managers, toxicologists, geologists, engineers, public participation experts). |
