Assessed the distribution, sources, and transport mechanisms of chlorofluorocarbons (e.g., Freon), chlorinated solvents, and gasoline antiknock chemicals into the Delaware River (river sediment and surface water), and in an aquifer beneath the Delaware River. Analyzed data collected over 2.5 miles of coastline, including results of dual frequency echo-sounder for bathymetric mapping, side-scan sonar to map sediment types, vibratory coring to map lithology of sediment and depth to an underlying aquifer, and push-probe and grab confirmatory sampling of sediment. Temporary wells were advanced beneath the riverbed to collect groundwater samples. Identified aquifer subcrop and DNAPL beneath the river, and calculated plume mass flux discharge to the river.

“… he impressed me with his ability to identify important details of contamination at the site, as well as build coherent conceptual models of groundwater and sediment contamination based on sound analysis and integration of multiple datasets. He was able to describe contaminant behavior at multiple scales, while at the same time focusing on the key issues and conveying the big picture. As Andrew continued to educate the Science Advisory Board at subsequent meetings, I was always impressed by his outstanding analytical and communication skills. He is sincere and very enjoyable to work with, and it is with overwhelming support that I recommend Andrew for developing sustainable approaches and solutions in the site remediation process.”
