Owen Cadwalader Presents at NovCare 2011

On Tuesday, May 10, 2011, Owen Cadwalader, a geochemist in Geosyntec's Boston office, presented at NovCare 2011, a forum on advanced methods for subsurface characterization and monitoring organized by leading universities in the United States and Germany. In his presentation titled, "Real-time and Low Cost Performance Monitoring Methods for Ozone Treatment of VOCs in the Vadose Zone," Owen discussed a real-time soil gas monitoring system developed by Geosyntec to examine the performance of an ozone injection remedy for a mix of VOCs in the subsurface with the objective of optimizing the efficiency of installed systems.

Owen also presented results of the firm's work with the Waterloo Membrane Sampler (WMS), demonstrating that these innovative gas samplers offer a low-cost, qualitative alternative to more expensive soil sampling techniques by providing compatible soil gas data.
