Mr. Jeff Wong TreadweIERdlo <br /> 22 November 1999 <br /> Page 3 <br /> • Selected samples will be analyzed for volatile organic compounds by EPA Method 8010 <br /> • We will direct the laboratory to mix select samples into composite samples for additional <br /> chemical analysis. Composite samples will be analyzed for semi-volatile organic <br /> compounds by EPA Method 8270. <br /> • Two grab groundwater samples will be analyzed for TPH as gasoline, diesel, and motor <br /> oil by EPA Method 8015M, and volatile organic compounds by EPA Method 8260. <br /> Waste Disposal <br /> Soil generated during the soil boring activities, and water generated during decontamination <br /> procedures will be drummed, labeled, and disposed of once the chemical analyses results are <br /> known. <br /> REPORTING <br /> Report preparation will begin immediately following the completion of the field work. The <br /> report will present the results of the field investigation, including boring logs, and soil and <br /> groundwater sampling results. Figures showing the location of the borings will be prepared, as <br /> will figures posting significant findings from the laboratory analyses. <br /> Please call with any questions regarding the proposed investigation. <br /> Sincerely yours, <br /> TREADWELL& ROLLO, INC. <br /> 2 C 0 <br /> David G.
