Dr. Bessinger specializes in environmental chemistry and the analysis of fate and transport of arsenic, metals, radionuclides, and organic contaminants in the environment. His expertise includes designing and conducting contaminant fate and transport studies, environmental forensics investigations, and water quality assessments. His consulting services include obtaining and interpreting geochemical and isotopic data, developing reactive transport models for sediment and groundwater evaluations, preparing site treatability studies, and investigating the sources of contaminants for litigation, insurance claims, and Natural Resource Damage Assessments. Dr. Bessinger’s expertise in geochemistry and reactive transport modeling is routinely used in monitored natural attenuation (MNA) investigations and geochemical compatibility evaluations for managed aquifer recharge (MAR) projects.
