ASC Environmental was retained to provide geological consulting services at the BF Goodrich Superfund Site in Calvert City, KY. Our work focused on developing a detailed subsurface conceptual model to support ongoing remediation and risk assessment efforts.

Geologic Conceptual Site Model for US Superfund Site

ASC Environmental was engaged as a consultative partner in the development of a Geological Conceptual Model (GCM) for the BF Goodrich Superfund Site located in Calvert City, Kentucky — a complex site with a legacy of industrial activity and associated subsurface contamination. Working collaboratively with project stakeholders and under the technical leadership of Battelle and Parsons, our role was to provide specialized interpretation of site subsurface conditions in support of long-term remediation planning.

The GCM process integrated extensive borehole data, including sonic cores and split spoon samples, which revealed interbedded layers of fine to medium sands, stiff clays, silts, and gravel deposits across various depths — in some cases extending beyond 100 feet below ground surface. Particular attention was given to hydrostratigraphic unit identification, including low-permeability clay layers acting as confining units and more transmissive sand/gravel zones influencing contaminant migration.

ASC synthesized this lithologic information into a 3D conceptual model that reflected both geologic variability and hydrogeologic function, informing risk assessments and guiding recommendations for monitoring well placement and further data collection. The model also helped delineate potential preferential pathways for groundwater movement and contaminant transport, which were crucial for evaluating long-term remedial technologies.

This effort supported USEPA and state environmental objectives by improving technical clarity at the site, reducing uncertainty in future design phases, and ensuring that remediation strategies are both targeted and effective. Our consultative contributions continue to assist in aligning regulatory, engineering, and community priorities around data-driven environmental solutions.
