LEVINE•FRICKE <br /> compounds in soil samples from the Site using biological <br /> treatment processes. Laboratory process treatment conditions <br /> will be varied in order to assess the optimum conditions for <br /> field implementation of a bioremediation program for the <br /> petroleum-affected soils. The results of the biotreatability <br /> studies will be used to estimate the duration of the soil <br /> treatment activities and the cost associated with this <br /> treatment. <br /> Task 3: Evaluation of Slurry Nall Barriers <br /> Based upon our experience and the preliminary literature <br /> review we have conducted concerning the ability of <br /> soil-bentonite slurry walls (SBSWs) to act as a barrier to <br /> heavy petroleum products, it is our opinion that a SBSW would <br /> serve as an effective barrier. However, prior to a final <br /> design, a laboratory compatibility testing program is <br /> recommended. <br /> Task 4: Project Management and Meetings <br /> Included in this task are scheduling and oversight of the <br /> tasks described above, cost tracking, and interface with <br /> Sunboro and their legal counsel. The project manager for this <br /> project will be Mr. John Sturman, Senior Project Geotechnical <br /> Engineer, who will oversee the investigative work and be the <br /> primary contact for Sunboro. Mr. Charles Pardini, Project <br /> Geologist, will coordinate field work and assist Mr. Sturman <br /> with data evaluation. Mr. Jeffrey Thomas, Senior Project <br /> Scientist, will direct the biotreatability studies. Mr. Ted <br /> Splitter, P.E. and Principal Geotechnical Engineer, will <br /> review the work related to the soil characterization and the <br /> slurry wall evaluation. Mr. James D. Levine, P.E. , Principal <br /> Engineer and President of Levine•Fricke, will assist Mr. <br /> Sturman. <br /> Task 5: Data Evaluation and Report Preparation <br /> Based upon the data collected, a report will be prepared by <br /> Levine-Fricke to present the methods and results of our <br /> investigation, our conclusions and recommendations to Sunboro, <br /> and the estimated costs associated with remediation of the <br /> petroleum-affected soils at the Site. <br /> SCHEDULE <br /> We estimate that the Scope of Work outlined above will be <br /> completed within three to four months of the initiation of <br /> field work. Results from the field work portion of the <br /> project should be available within about one month of <br /> commencement of this work. <br /> 4 _ <br />
