This Technical Report Addendum documents longevity and continued effectiveness of emulsified edible oil substrate for remediation of perchlorate and chlorinated solvents in groundwater. The project was funded by the Environmental Security Technology Certification Program ESTCP ER-0221. The substrate used for the demonstration was EOSregistered trademark, a commercially available concentrated edible soybean oilnutrient emulsion purchased from EOS Remediation, Inc. of Raleigh, NC. The demonstration was conducted at the Alliant Techsystems, Inc. site ATK in Elkton, MD. The field demonstration began in October 2003 with the initial performance monitoring period ending in April 2005. Because good results were observed, ESTCP funded an additional two years of monitoring to further evaluate the technology. The longevity and extended performance of the technology were evaluated by monitoring the impact of the emulsified oil on the aquifer permeability and continued changes in contaminant concentrations and biodegradation indicator parameters in the aquifer. Data obtained during the pilot test were used to demonstrate the cost-effectiveness of emulsified edible oils for remediation of perchlorate, chlorinated ethanes and ethenes in groundwater through enhanced biodegradation.
