SERDP ER-1552:
Measurement and Modeling of Ecosystem Risk and Recovery
for In Situ Treatment of Contaminated Sediments

Demonstration Site: Hunters Point Shipyard, South Basin, Parcel F

Technical Objectives

  • Demonstrate the utility of biodynamic modeling for predicting PCB uptake by key species
  • Develop rapid tools to measure pore-water and available PCBs
  • Develop a protocol for assessing ecosystem recovery after in-situ remediation

    • 1. Demonstrate the utility of biodynamic modeling for predicting PCB uptake by key species

    Parameterize biodynamic model in the laboratory to predict tissue concentrations for key species

    Demonstrate applicability of biodynamic model in the field

    2. Develop rapid tools to measure pore-water and available PCBs

    Define kinetics of passive samplers and test them for pore water measurements in the field

    Assess pore water diffusion & mass transfer with heat flux measurements from data loggers vertivally deployed in the sediment.

    3. Develop a protocol for assessing ecosystem recovery after in-situ remediation

    Conduct benthic community surveys to assess recruitment pool for Hunters Point
