Geo(vgrcalTeelwcs Inc Page 3 <br /> Soil&Groundwater Investigation Report <br /> J M Equipment <br /> Pioject No 507 2 <br /> July 5,2001 <br /> ' 2 1.1 Soil Sampling Procedure <br /> Soil samples were collected foi geologtc,al and analytical evaluation at five-foot intervals in <br /> borings SB-6, MW-7 and MW-10 Boring MW-109 was free drilled to 75' due to its <br /> proximity to borings MW-9 and SB-109 Samples were obtained from this boring at 75 and <br /> 80' bgs A piofessional geologist working under the supervision of a registered geologist <br /> maintained a boring log providing sediment description using the USCS and field <br /> ' observations Soil samples were collected in 6 0-inch brass liners using a 2 0 inch modified <br /> California split spoon sampler All soil samples were sealed with Teflon sheets, capped <br /> with plastic end caps, labeled, and placed in a cooler at 4° Celsius for transport to the <br /> laboratory following Chain of Custody protocol The boring logs ate included as Appendix <br /> B <br /> ' Since only selected soil sample collected were submitted for laboratory analysis, a screening <br /> process was used to gathei additional information through field observation noting the <br /> following <br /> ■ sediment type, especially grain size and clay content <br /> ' ■ moisture content <br /> ■ visible evidence of contamination, i e , color change due to reduction of iron or <br /> discoloration from hydrocai bons and other pollutants <br /> ■ readings above background on a organic vapor meter (OVM) <br /> The OVM is a portable photo ionization detector that uses a 10 0 eV lamp to detect <br /> compounds with ions,-ation potential below 10 0 eV (hydrocarbon range) <br /> Details on the geology encountei ed during the completion of the sampling event as well as <br /> ' the field observations are included in Section 3 3, Geology and Field Observations <br /> 2.1.2 Soil Laboratoi y Analyses <br /> ' Based on field screening observations, one to three soil samples from each borehole were <br /> submitted to Sherwood Laboratories of Hilmar (State Certified Laboratory #1400) for <br /> analysis of <br /> m benzene, toluene, ethylbenzene and ylene (BTEX by EPA method 8020), <br /> 0 methyl tertiaiy butyl ether (MTBE by EPA method 8020 with confirmation by EPA <br /> method 8260) <br />' O gasoline range petroleum hydrocarbons (TPH-G by EPA method 8015(m)) <br /> A Chain of Custody was completed for all samples collected and tracked to ensure sample <br /> integrity The detection limits for these compounds are included in Appendix A <br /> In addition to the preceding Lhermcal tests, five soil samples were selected from different <br /> soil types for testing of geophysical parameters, (including but not limited to moisture, grain <br /> s17e distribution, density, permeability and organic content), by ASTM methods D5084, <br /> D2434, D422 and D2974 The samples were submitted to Cooper Testing Lab, Inc in <br />' Mountain View, CA <br /> The results of the geophysical parameter testing are included in Appendix D <br /> 1 <br />
