Engaged to develop a Conceptual Site Model (CSM) for the Landfill Superfund Site. The CSM was constructed using a multiple lines-of-evidence approach, integrating historical and contemporary soil, groundwater, sediment, and surface water data to evaluate contaminant fate and transport.

Key Findings included Identification that a former sludge disposal area and 2,000 buried drums were identified as the primary contributors of chlorinated volatile organic compounds (cVOCs), PCBs, and metals such as chromium, lead, nickel, and zinc in soil and groundwater.

Groundwater-to-surface water discharge pathways contributing to low-level detections in nearby surface waters, and Chromium and PCB impacts in surface water and downgradient groundwater were found to be negligible, confirming limited partitioning from soil to groundwater.
