Aaron G.B. Williams, Ph.D.

Principal

Aaron has more than ten years of research and site assessment experience including research project design, implementation and authorship, bench- and pilot-scale treatability testing, and remedial system design and implementation. Site assessment experience includes soil, sediment and ground water investigations with an emphasis on presenting data in an informative GIS format. Modeling experience relevant to site assessment includes hydrogeologic modeling of solute transport, geochemical modeling, evaluation of natural attenuation processes for petroleum hydrocarbons and chlorinated solvents, geospatial analysis and risk assessment. Aaron has experience with assessment and remediation for metals, PCBs, petroleum products and chlorinated solvents.

Prior to joining EPS, Aaron completed a termed appointment with the U.S. Environmental Protection Agency Office of Research and Development (ORD). His work with ORD focused on the relationship between metal speciation and metal bioavailability in sediments and soils. In addition, he characterized metal speciation, fate and transport in other systems including mine waste products and groundwater-surface water transition zones.
