Geosyntec professionals will be making presentations at a conference sponsored by the National Groundwater Association (NGWA) on September 26 and 27, 2011.
David Adilman (Boston) and Carl Elder (Boston) will be co-presenting "Application of Bioremediation for TCE in a Crystalline Bedrock Aquifer." The presentation summarizes the results of studies demonstrating how emulsified vegetable oil (EVO) and bioaugmentation were used to reduce trichloroethene (TCE) concentrations in deep bedrock (250 feet below ground surface) from concentrations exceeding 100 ppm to non-detect levels in only three months. Chris Arsenault (Boston) contributed to the development of the presentation as a co-author.
Erik Petrovskis (Ann Arbor) will be presenting "Remediation of a Gasoline Release in Fractured Dolomite Using a Bedrock Extraction Trench." Erik will present study results on the use of an extraction trench installed 18 feet below ground surface and 8 feet into bedrock to improve the capture of a gasoline and MTBE release in the Midwest that had resulted in the closure of several municipal and residential wells. David Adilman and Rick Skowron (Oak Brook, Illinois) contributed to the development of this presentation as co-authors.
The conference, entitled NGWA Focus Conference on Fractured Rock and Eastern Groundwater Regional Issues, provides the opportunity for groundwater professionals, state and regional regulators, and resource managers to interact, compare characterization techniques and remedial solutions, and explore policy initiatives regarding the fractured rock environment. As fractured rock aquifers serve as the primary source of groundwater for many areas of the world, keeping up with evolving science and developing technologies that provide a better understanding of the physical and chemical nature of these systems, as well as the fate and transport of both natural and anthropogenic contaminants, is necessary.
