Hull &Associates Inc. Page 2 July 14, 2016 Hull & Associates Inc. Doug Stuart Dear Mr. Stuart: Innovative Environmental Technologies Inc. (IET) has included a revised remedial design and quotation for the Oliver Plow site located in South Bend, IN. The site has been identified as having impacted soils and groundwater due to the historic use of tetrachloroethene (PCE) and trichloroethene (TCE). Based on the provided soil borings, groundwater concentrations, screened intervals for monitoring points and historic geochemical parameters, a design which will stimulate reductive dechlorination processes in the subsurface is proposed. Concentrations of PCE and its reaction products, trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE) and vinyl chloride (VC) indicate that reductive dechlorination is occurring at the site at a rate that needs to be stimulated. The recommendations presented herein are based on IET's experience at over 200 similar sites, IET's experience with a variety of oxidative and reductive technologies and IET's ability to integrate a variety of remedial products forthe optimal remedial process. Further, the remedial approach presented herein is covered by three IET United States Patents and one IET United States Patent Application. 1) "Apparatus for In -Situ Remediation Using a Closed Delivery System", Patent Issue Date: May 16, 2006 Patent Number 7,044,152. 2) "Method for Accelerated Dechlorination of Matter', Patent Issue Date: October 31, 2006, Patent Number 7,129,388. 3) "Method for Accelerated Dechlorination of Matter', Patent Issue Date: May 12, 2009, Patent Number 7,531,709 (continuation of "388"). 4) "Method for the Treatment of Groundwater and Soils Using Mixtures of Seaweed and Kelp", Patent Application #6124509, July 2009. 5) "Inhibition of methane production during anaerobic reductive dechlorination, by restricting the effectiveness of the enzymes and coenzymes that catalyze methanogenesis" Patent Application # 13/785,840, March 2013. 6) "Use of encapsulated substrates to control the release rates of organic hydrogen donors and accelerate the biotic process of anaerobic reductive dechlorination in soil and groundwater" Patent Application # 13/891,934 November 2012. The following proposal will set -forth a lump sum price for the design, implementation and follow up of this process. The following proposal is designed to mitigate off -site migration and address source area contamination that is local to the injection areas on -site.
