Impact/Purpose:
Provide technical updates regarding long term monitoring of contaminated sediment sites. CLU-IN Virtual workshop
Description:
Weight of Evidence Approach using Multiple Lines of Evidence Biological LOE – assesses biological endpoints, e.g., fish reproduction, diversity of species, toxicity Chemical LOE – measures that relate to contaminant concentrations, e.g., post-remedial surface weighted concentrations, reductions in fish tissue levels Physical LOE – volume and mass removed, e.g. pounds of PCBs dredged Modeling - physical and hydrodynamic modeling, performance modeling, food web modeling
