Solvent contamination was first reported at the site in 1993. More than 10 years of standard remediation practices including pump & treat, air sparging and soil vacuum extraction, showed little to no effect on contaminants. Concentrations of trichloroethene (TCE) in groundwater ranged from 2000 to 4000 µg/L under generally oxidative conditions. The Army Environmental Command (AEC) hired Solutions-IES for its patented Emulsified Oil Substrate (EOS®) Process. For less than $650,000, Solutions-IES treated the source area with EOS® (www.eosremeditaion.com) quickly creating anaerobic reducing conditions and stimulating enhanced reductive dechlorination. After only six months post-injection and distribution of EOS® throughout the aquifer, TCE concentrations were reduced by more than 99.9% to < 1 µg/L. Solutions-IES’ innovative engineering design using EOS® achieved the site’s regulatory goal in a cost-effective and timely manner. The Army has since transferred the property and the new owner is redeveloping the site for commercial/retail use.
