April 9, 2009 Next week's Design and Construction Issues at Hazardous Waste Sites (DCHWS) Conference in Philadelphia, PA - sponsored by both the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers - is expected to draw a record number of environmental professionals to discuss the latest remediation strategies and technologies. Among those presenting and exhibiting at this year's conference is Stratham, NH-based firm XDD, which will discuss its recent success at remediating the contaminants TCA, PCE and 1,4-Dioxane, as well as the fate and transport of mobilized metals resulting from in-situ chemical oxidation (ISCO) technologies. XDD and MACTEC's presentation, titled "Application of Alkaline Activated Persulfate and Evaluation of Treatment Residuals," will be conducted by XDD senior project manager Scott Crawford and firm president Mike Marley on April 14 at 1:30PM at the Loews Philadelphia Hotel at 1200 Market Street in Philadelphia, PA. In the spring of 2007, XDD was selected by a Fortune 50 company and its prime contractor, MACTEC Engineering, to design and apply an ISCO remedy at an intensively active, high-security, manufacturing facility in New England which produces specialty aircraft components. The site remedial goal was to reduce the key site contaminants - 1,1,1-TCA; PCE; and 1,4-Dioxane - to below 1 mg/L in groundwater. Meeting the source reduction criteria was crucial to the overall site remediation plan; this level of reduction was required to make longer-term natural attenuation of the plume viable, and to achieve protection of a nearby surface water body. Failure to achieve the source area reduction goals would have required the client to implement more costly plume control. Find out how XDD achieved the client's goals at this site with an Alkaline Activated Persulfate (AAP) approach at next week's presentation. Environmental professionals who are interested but unable to attend the DCHWS conference in Philadelphia are encouraged to contact Scott Crawford or Mike Marley directly for more information.
