I would like to take this opportunity to recognize the extraordinary efforts of Diversified Engineering Inc. at the Countywide Landfill remediation site in East Sparta, Ohio. I worked with DEI from April 2008 - October 2009 on an aggressive, broad reaching environmental remediation project at this site. One of the main priorities of EPA was to safely and expeditiously excavate a massive firebreak involving over 400,000 cubic yards of waste. This work was a critical part of our effort to isolate and contain and underground reaction/fire at this site, thereby limiting the impact on the surrounding community. The design of the isolation break, along with the quick response to accommodate changes in the gas, leachate and drainage features, was greatly appreciated. The fact that the excavation to the berm separating Cells 5 and 7 was right on target is a testament to the great work performed by DEI. In addition, DEI’s attention to detail was greatly appreciated in the design of the many features necessary to minimize impacts from the remediation area, such as the flare pads, condensate sumps, surface water drainage/conveyance/storage structures, as well as the controlling reaction byproducts and odors. Finally, I would like to recognize the responsiveness, great attitude, and cooperative spirit demonstrated by the DEI field crew. They responded quickly to located site features and provide advice on dealing with conflicts between site plans and construction activities that arose each day, which greatly assisted in keeping work on schedule.

We have worked with Diversified Engineering, Inc., for several years. Chris Bower and his staff are responsive, have great attention to detail and their services are very competitive.
