Requirements

  • The 2022 ROD for the Site calls for excavation of contaminated soil and treatment on-site using Low Temperature Thermal Desorption (LTTD). Treated material will be tested to ensure the achievement of remedial goals as defined in the ROD. Treated material will be used to backfill the areas that were excavated. In the wetland, the final 0.61 meters (approximate) of backfill material will be blended with organic matter and bioaugmented granular activated carbon (GAC). This bioaugmented GAC will include the addition of microbes that are capable of degrading the organic contaminants present in groundwater. If concentrations of metals in this upper layer are detected at concentrations that exceed ecotoxicity concentrations, the material shall be blended with a metal stabilization agent. Creating a bioreactive zone on the surface of the wetland will provide for long term permanence of the remedy via bioremediation of residual contamination from upwelling groundwater
  • The selected remedy combines elements of the originally selected remedy, bioremediation, with the contingent remedy, Low Temperature Thermal Desorption (LTTD). It specifies the depth of excavation for shallow sediment and addresses principal threat waste in the wetland to depths practicable. The selected remedy also addresses potential metals toxicity in wetland sediment by adding a stabilization agent after treatment via LTTD
