ABOUT MICHAEL SWEETENHAM

Hydrogeologist with over 10 years of experience in environmental assessment, investigation, characterization, modeling, remediation, and mining. His skill set combines the critical thinking ability and technical expertise of an analytical hydrogeologist with the computational skills of a modeler to develop conceptual site models (CSMs), 3-dimensional visualizations, and numerical groundwater models. He serves as a technical expert and works with multidisciplinary teams on small and large sites impacted with organic and inorganic constituents, including per- and polyfluoroalkyl substances, 1,2,3-trichloropropane, 1,4‑dioxane, chlorinated solvents, hydrocarbons, metals, and radionuclides. He has worked for industrial, commercial, municipal, and other clients under regulatory frameworks, including state-led cleanup programs, CERCLA, and RCRA.He has extensive field experience, including drilling oversight of direct push technology, hollow stem auger, sonic, air-rotary, and mud-rotary rigs to install monitoring, remediation, injection, and residential wells; collection of soil, sediment, rock, surface water, and groundwater samples; and using high resolution site characterization and geophysics to inform CSMs. He designs, implements, and manages successful in situ bioremediation/bioaugmentation, in situ chemical oxidation, pump and treat, phytoremediation, excavation, ex situ chemical oxidation, soil vapor extraction, sub-slab depressurization system, and air sparging projects. In addition, Mr. Sweetenham is well versed with ArcGIS Pro, Leapfrog, and analytical and numerical models, including BIOSCREEN, BIOCHLOR, REMChlor, HELP, VS2DT, VLEACH, AnAqSim, ParFlow, MODFLOW, and MT3D.
