r <br /> i Limited Subsurface Site Investigation Results Report <br /> Moore Petroleum Bulk Plant,5491 F Street,Banta,San Joaquin County,California <br /> Page 5 <br /> Soil_Sampling <br /> Soil samples were collected from each boring at five-foot intervals and at obvious lithologic <br /> i changes. Three soil samples from borings MW-13, MW-14, MW-16 and MW-17, were <br /> submitted to a State-certified laboratory for analysis. In order to correlate new soil analytical <br /> data with data collected during previous subsurface investigations, the samples were collected <br />{ from each of the sampled borings at approximate depths of 5-, 10-feet bgs and total depth. <br /> Soil lithology and visual observations for each sampled boring were recorded in the field. Soil <br /> samples were field screened with a photo ionization detector. All sampling was conducted in <br /> accordance with the Apex SOP included in Appendix B. Soil encountered during the installation <br /> of the wells was logged according to the unified soil classification system, under the supervision <br /> of a State of California registered professional geologist. Boring logs for each of the wells are <br /> presented as Appendix C. <br /> CONE PENETRATION TESTING (CPT) ACTIVITIES <br /> On November 9, 2005, Apex personnel supervised the advancement of two CPTs (CPT-1 and <br /> CPT-2) to 80 feet bgs, performed by Gregg Drilling Company of Martinez, California (Figure 2). <br /> Groundwater samples were collected at identified sandy layers as indicated by the Soil Behavior <br /> Type printout for CPT-1 and CPT-2 (Appendix D). The five groundwater samples collected <br /> from CPT-1, and the four groundwater samples collected from CPT-2 were submitted to a State <br /> certified laboratory for analysis of the following analytes listed below. Upon completion, the <br /> CPT test borings were destroyed using Portland cement to surface. Native material was used to <br /> complete CPT-1, and Portland cement was used to complete CPT-2. <br /> l <br /> i <br /> I. <br />{ t <br /> f <br /> f <br /> i <br />
