Select Projects

Subsurface Chemical Release:  Provided expert testimony at trial on the timing of a subsurface hydrocarbon leak from an underground pipe.

Contamination Analysis:  Performed a forensic analysis of contamination from multiple point sources in an estuary located in a heavily populated area.  Contaminants included PAHs, PCBs, dioxin/furans, and metals.  The forensic analysis was used to provide a scientifically sound cost-allocation model for use in negotiations.

Groundwater Analysis:  Developed a conceptual framework for the movement of herbicides from their application point to groundwater supplies, and through the subsequent retention and slow release over a multi-decade timescale.  Analyzed multiple sites with disparate hydrology using several national databases.

Sediment and Chemical of Concern Transport:  Served as a neutral technical advisor to the allocation team for a large multi-party sediment site, addressing topics that include the long-term quantitative impacts of tidal surface water transport on chemical movement, as well as chemical forensics, watershed modeling, and tidal hydrodynamics.

Indoor Air Chemical Analysis:  Analyzed the behavior and movement of chemicals in building materials and indoor air, including sorption and partitioning, the role of HVAC and ventilation, and equilibrium conditions, using modeling, data analysis, and chemical forensics analysis.

Chemical Forensic Analysis:  Provided expert testimony at a deposition and trial on dioxin and PCB chemical forensics and transport pathways at a former multi-party industrial site with soil and sediment impacts.

Surface Water Assessment:  Analyzed the long-term behavior and transport of fluorinated compounds in a tidally influenced surface water body in a highly urbanized  corridor.
