The objective of this presentation is to show the benefits of using multiple lines of evidence following the Federal Contaminated Sites Action Plan Weight of Evidence guidance.
Jennifer Cook, Golder Associates Ltd.
The objective of this presentation is to describe a case study that applied an iterative risk assessment approach to support site closure, sequentially increasing site-specific data to refine and increase the realism of risk estimates, and specifically targeted to pathways requiring further detailed evaluations.

The objective of this presentation is to discuss the fish-specific toxicity reference values available for use as benchmarks of effects to fish in aquatic ecological risk assessments identified through a literature search and the review of selected ERA case studies from federal sites. The water quality guidelines reviewed for their potential suitability to be used directly as fish-specific TRVs, or as the basis for future development of values specifically for protecting fish will also be shared.
