<P>The Military Engineer L No. 66359 Sustainable Superfund Remediation By John Wrobel and Joseph P. Gross, M.SAME A Superfund remedial action performed at Aberdeen Proving Ground, Md., demonstrates a successful integration of waste reduction and traditional environmental remediation. T he Comprehensive Environmen- tal Response, Compensation, and Liability Act of 1980 (CERCLA), or Superfund, remedial action of a 15-acre former salvage yard, ?re training area and disposal area at Aberdeen Proving Ground (APG), Md., is a success story of collaboration, stakeholder engagement and safety. It also is an example of in- corporating sustainable practices into a project to reduce waste. The remedia- tion project was accomplished with an approach that reduced environmental impacts, thus meeting the objectives of Executive Order 13423, Strengthen- ing Federal Environmental, Energy and Transportation Management, to con- duct activities in an environmentally, economically and ?scally sound, inte- grated, continuously improving, ef?- cient, and sustainable manner. The site, known as the G-Street Salvage Yard, was on the Superfund National Priorities List for industrial surface and sub-surface soil contamination as well as complications of potential munitions and explosives of concern and chemi- cal warfare materiel. The site was used originally during World War I as a rail- road yard, then for salvage yard opera- tions from the 1940s until the late 1960s. Salvage yard operations included scrap wood and metal recycling and a smelt- ing operation for lead reclamation. The western portion of the roughly triangu- lar site also was used for ?re training, including an earthen ?re training pit. Another area received ash and metal residue material for scrap metal recov- ery and sale. The remediation was led by the Environmental Division of the APG Di- rectorate of Public Works with Weston Solutions Inc. as the primary contractor. Waste Minimization and Sustainable Operations An important goal of the remediation effort was to minimize the quantity of contaminated media disposed, and to increase the diversion of solid waste as appropriate in a cost-effective man- ner. The team accomplished this goal through a multi-pronged approach, demonstrating expertise with applica- bility at remediation projects around the world. Waste reduction techniques, further detailed below, included: sincremental excavation using 12-in lifts where chemical contamination was present at shallow depths; scomprehensive in-situ soil screening using x-ray ?uorescence technology and sampling using an analytical lab- oratory; ssurgical excavation to minimize the number of trees removed; sleveraging a wood-for-fuel program to reuse trees that could not be saved; ssegregation of recyclable metals, a Environmental Engineering Workers in full Level-A protective gear conduct remedial investigations in a vapor containment structure at the location where chemical warfare materials were suspected at Aberdeen Proving Ground, Md.
