MD&E is supporting Michigan State University through input regarding the hydrodynamics and fate and transport of chlorinated solvents and hexavalent chromium within the aquifer system in the vicinity of Schoolcraft, Michigan. Dr. Mayotte provides insight from over 18 years of experience with investigating the sources and delineation of multiple plumes of groundwater contamination specific to the Schoolcraft area. Activities include participation in the conceptualization and execution of numerical models to estimate the magnitude of vertical hydraulic communication of adjacent strata in response to inoculate and substrate delivery schemes, and the fate of hexavalent chromium under a range of redox conditions.
