Duncklee & Dunham, PC have undertaken an innovative remedial action project to address metals contamination in the shallow and intermediate groundwater at an industrial facility. Metals contamination in groundwater represents one of the more difficult remediation scenarios because metals do not degrade and have limited capacity to attenuate under normal aquifer conditions. Our staff has extensive experience in the assessment and remediation of metals and other inorganic soil and groundwater contamination resulting from agri-chemical, electronics, plating and coating, wood treatment and mining operations. Although the existing groundwater plume is still confined to the client’s property, 3D groundwater fate and transport modeling verifies that groundwater metals contamination will ultimately exceed regulatory standards at the facility boundary if left unabated. These metals continue to be released to the groundwater from a centralized soil source area. Metals in the groundwater beneath these source area soil act as a source for the strengthening plume. Duncklee & Dunham’s senior staff, working with nationally recognized geochemical and groundwater modelers and treatability experts developed a unified strategy to address the existing groundwater plume and the continuing source area. Chemical reagents will be injected into the groundwater to enhance the metals adsorption capacity of the aquifer soil particles. Bench-scale column leaching testing, field pilot testing with associated sampling and testing, and additional modeling will be used to develop design criteria and to validate the application. The objective of the program is a unified remedy for both the current groundwater plume and the future release of additional metals contamination from the source area. Our comprehensive approach is to apply this remedy to safeguard the facility boundary from the existing plume while also using it was a protective treatment in the plume core subject to further leaching from the source soils. By having a strong adsorption capacity directly beneath the source soils, the subsequent remediation of those soils can be minimized. Mr. Ernie Parker, PE, PG leads Duncklee & Dunham’s team in applying an in situ process – Soil Adsorption Enhancement – as a cost effective way to address the inorganic site contamination. This enhancement program is another example of Duncklee & Dunham’s intent and ability to use innovation and creative thinking to find a workable solution to serious environmental challenges.
