. . . ..... . ._. . ....... .... <br /> _ A <br /> � KLEINFELDER <br /> III. SCOPE OF WORK <br /> Task E01 - Soil Sample Collection <br /> Four soil borings will be hand augered in the area of former sample 6-8. Three of the borings <br /> would be advanced within 5 to 10 feet from former sample 6-8 in an attempt to further define the <br /> lateral extent of the lead-affected soil. The fourth boring would be advanced in the location of <br /> sample 6-8 in an attempt to define the vertical extent of the lead-affected soil. All borings will <br /> be advanced to a depth of 5 feet. Soil samples will be collected at one foot intervals beginning at <br /> a depth of 1 foot below surface grade (bsg). The samples will be obtained using a <br /> decontaminated hand auger/slide hammer sampler. The technician will hand auger down to the <br /> desired sampling depth and sample the soil by slide hammering the sampling device which holds <br /> a decontaminated stainless steel sleeve. <br /> Task E02 - Laboratory Analysis <br /> Each of the soil samples collected for quantitative analysis will be submitted under chain-of- <br /> custody control to Sequoia Analytical Laboratories (Sequoia) of Sacramento, California. <br /> Sequoia is certified by the California Department of Toxic Substances to perform the requested <br /> analyses. <br /> A total of six (6) soil samples from the site will be submitted for analysis. The samples will be <br /> submitted for: <br /> • Total Lead by EPA Methods <br /> • Soluble Lead by STLC <br /> The samples will be analyzed on a-5-day laboratory turnaround schedule to acquire the analytical <br /> data. <br /> Task E03 - Report Preparation <br /> Upon completion of the soil sampling and our receipt and review of the analytical results, a <br /> separate letter report will be prepared for client review. The report will include: <br /> • A description of field activities, observations, and protocols <br /> • Tabularized results of soil sample analysis with copies of certified analytical <br /> laboratory results with chain-of-custody documentation <br /> • Conclusions and recommendations <br /> 20-3978-OI.W32/20I7P110 Page 5 of 7 <br /> C 1997 Kleinfelder,Inc.
