Forensic Chemistry for PCBs at a Rail Yard
Gradient evaluated the nature of PCB contamination at a former rail yard Superfund site as part of a cost allocation case. We reviewed and analyzed more than 15 years of chemical data from soil; sediment; and groundwater samples. Gradient also conducted a site visit and collected soil samples for advanced congener fingerprinting analysis using GC/MS-SIM. Gradient provided an expert witness report summarizing the sources and approximate timing of contaminati
