CEG researches new technologies and has the engineering and technical capabilities to design and implement innovative remedial alternatives. To ensure a higher probability of success, it is CEG's practice to pilot test a remedial technique prior to installing the selected remedial system. The success or failure of the pilot test is integral in establishing the likelihood of success for a remedial alternative and also minimizes the potential cleanup costs.
CEG staff have managed the only two known Maine sites that have been remediated to Maine stringent groundwater quality standards using primarily in-situ methods. Each of the two sites threatened the water quality of a public water source and were ranked by the Maine Department of Environmental Protection on their top 10 Priority List.
