it 'F <br /> f li <br /> ry :. <br /> } <br /> used for the annular space seal from the lower seal to :the , <br /> surface. Specific detail for well design is in Appendix - A, <br /> Monitor well Boring and Construction Logs . A traffic box was set } <br /> in concrete for this well and fitted with a locking system and ' <br /> well ID tag. <br /> Field personnel placed.�!the contaminated waste material (cuttings) <br /> produced during drilling on and covered with visqueen. The <br /> rinseate from steam cleaning operations are contained in labeled <br /> 55 gallon drums on site . <br /> RESULTS <br /> i <br /> The analytical results; methods and depths for soil samples from f <br /> drilling the monitor well is tabulated in Table 1 . The Matrix <br /> Environmental Laboratories (DHS# 1.676) analytical laboratory <br /> report of the soil forthis site is presented in Appendix B. <br /> !3 <br /> Soil SsjM es i! <br /> As discussed earlier, lithe soil boring samples that were selected <br /> for analysis were based on the criteria of the highest Photo <br /> Ionization Detector (PID) readings, two representative vadose <br /> zone samples, top of water and at the base of the borehole. This <br /> information is presented in Table 1 . <br /> Petroleum hydrocarbons were not detected in soil samples except <br /> MW8-30 at or above detection limits for the analyses run, TFH as <br /> gasoline and Volatile Aromatic Hydrocarbons (BTEX) . The. 30 <br /> foot soil sample, MW8-30 , had . 017ppm of benzene. <br /> The drilling and installing of MW8 was to implement Western Geo- <br /> Engineers' workplan proposal of January 4, 1993 . This workplan <br /> proposed that the ground water from MW8 would be sampled during <br /> the next quarterly monitoring at this site . This letter is to <br /> report and document the drilling, installation and soil analysis <br /> for this well . The ground water results, local hydrology and. the <br /> methods and procedures". for drilling, well development and ground <br /> water sampling will be presented in the next quarterly monitoring <br /> report . <br /> The services performed by Western Geo-Engineers, a corporation, <br /> working directing under California Registered Geologist #3037 <br /> and/or California Contractor #51.3857, are conducted in a manner '. <br /> consistent with the level of care and skill ordinarily <br /> exercised by members of our profession currently practicing <br /> under similar conditions in the State of California, San <br /> Joaquin County and the City of Lodi . Please note that <br /> contamination of soil and/or ground water must be reported to. the <br /> appropriate agencies in a• timely matter. No other warranty, <br /> expressed or implied, ,is made. <br /> 1 <br /> I <br /> 2 <br /> ii <br />
