Geosyntec Staff Co-Author Two Articles in July 1, 2010 issue of Environmental Science and Technology

COLUMBIA, Md. — Geosyntec staff co-authored two articles in the July 1, 2010 issue of Environmental Science and Technology. The articles document two research projects that achieved significant advancements in the state-of-the-science regarding bioremediation of chlorinated solvents in groundwater. The first article, "Field Evaluation of Enhanced Reductive Dechlorination in Clayey Till" (44:5134-5141), co-authored by Neal Durant, PhD, and Evan Cox, MSc, of Geosyntec, and Phil Dennis of SiREM, describes a rigorous demonstration of in situ bioremediation and hydraulic fracturing for treatment of chlorinated solvents in low-permeability sediments. The research was completed in coordination with the Technical University of Denmark, with funding from the Danish Environmental Protection Agency.

The second article, "Comparing On-Site to Off-Site Biomass Collection for Dehalococcoides Biomarker Gene Quantification to Predict In Situ Chlorinated Ethene Detoxification Potential" (44:5127-5133), was co-authored by Erik Petrovskis, PhD, PE, of Geosyntec together with a team of researchers from the University of Tennessee, the U.S. Department of Energy (DOE), and the U.S. Navy. This project developed and validated an innovative method for collecting bacteria in groundwater field samples that will enable improvements in bioremediation performance monitoring while reducing sample collection costs. The research was supported by the U.S. Department of Defense as well as DOE.
