Assessment

Through the assessment of site conditions, the distribution of the constituents of concern is determined and the potential for exposure and risks are evaluated, including natural attenuation rates and the potential for ongoing sources.

Site Investigation Design

  • Legacy data management
  • Sediment and surface water sampling and analysis
  • Biota sampling and analysis
  • Bathymetric and geophysical surveys

Modeling of Data

  • Point source and non-source inputs
  • Sediment transport and distribution
  • Sediment contaminant transport and distribution
  • Fate-and-transport
  • Floodplain/mixing zone distributions
  • Surface water contaminant transport
  • Ecological food web

Assessments

  • Human health risk
  • Ecological risk
  • Natural recovery
  • Sediment stability
  • Feasibility of remediation approaches
  • Bench-scale/pilot-scale treatability
