N .. <br /> Mr.John Fleming <br /> November 22, 2000 <br /> Page 2 <br /> Relatively undisturbed soil Samples will be taken at approximately 10 foot intervals <br /> during drilling of the borings for construction of the monitoring wells. These samples <br /> will be examined in the field for lithologic description only_ No laboratory analyses are <br /> proposed for the soil samples. <br /> The locations and elevations of the monitoring wells will be surveyed by a land surveyor <br /> licensed in the state of California. As this is a "clean" site,soil cuttings from construction <br /> of the monitoring wells will be spread out in an unpaved area and left on site. Water <br /> from development and purging of the wells will also be discharged on site. <br /> Following construction of the ground water monitoring wells, they will be developed and <br /> sampled. The analytical program is based on the requirements presented in Table 3 of the <br /> WDRs. Each of the three ground water samples will be analyzed for the following <br /> constituents_ <br /> • Volatile organic compounds-EPA Method 8260. <br /> ;Extractable Fuel Hydrocarbons- modified EPA Method 8015(4). <br /> • Oil and grease-EPA Method 413.1. <br /> • Chemical Oxygen Demand (COD).-EPA Method 410.4. <br /> • Nitrate-EPA Method 300.0. <br /> • Specific Conductance -Method 2510B_ <br /> • Total Dissolved Solids (TDS)-EPA Method 160.1_ { <br /> • Sulfate- Method 300.0_ <br /> Chloride-EPA Method 300.0. <br /> • Dissolved Barium, Copper,Lead and Ziac-EPA Method 6010B. <br /> The laboratory analyses will be performed by a state of California-certified analytical <br /> Iaboratory, <br /> Task 3 - Report Preparation <br /> Following completion of the analytical testing, a report will be prepared to present and <br /> summarize the data. Also described in the report will be the well construction and <br /> ground water sampling procedures, and subsurface conditions encountered_ Copies of the <br /> drilling logs, well construction logs,well development forms, sample chain-of-custody <br /> forms and the analytical laboratory report will be included as appendices to the report. <br /> The fees for the scope of work described above are estimated to be$45,000. These <br /> services will be provided on a time and materials basis in accordance with our current <br /> Schedule of Charges 98-BNS)~. Bids received from three drillers for this work are <br /> enclosed_ Our fee is based on using the lowest drilling bid. <br /> ].trt]12200.Joc <br /> C�sfarrer•Foaisad Solutions <br /> 9Z ',A Pn:P Tr) c upr <br />
