Dr. Hyndman will discuss how ground water flow and contaminant transport models can be used both to design bioremediation systems and to evaluate the influence of heterogeneities on contaminant fate and transport. The Schoolcraft bioremediation system, which was developed as a multidisciplinary collaborative research effort between hydrogeologists, microbiologists, and environmental engineers, has achieved greater than 95 percent remediation efficiency over a period of three years. The lecture is co-sponsored by the National Ground Water Association.
