  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...

  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...
