Ground Zero Analysis,Inc. Page 3 <br /> Summary of Findings:Soil Investigation <br /> Project#2010.2 <br /> June 26,2013 <br /> 2.4 Soil Laboratory Results <br /> All six (6) soil samples analyzed came back non-detect for the above chemicals of concern. <br /> { The laboratory analytical data sheets are presented in Appendix A. A chain of custody <br /> i•+ document, listing all samples collected, accompanied the samples from field to laboratory, <br /> thereby providing a means to track the movement and ensure the integrity of the samples, and is <br /> also attached in Appendix A. <br /> 2.5 Geology & Field Observations <br /> The subsurface geology encountered during the completion of the boreholes is characterized as <br /> mostly clay with some silts and sands that were fine grained, loose, with thin layers containing a <br /> higher sand content. Soil samples for laboratory analysis were collected from the contact <br /> between the base of the upper sand unit and the top of the lower clay unit. This contact was <br /> encountered at 34.5', 36.5' and 31.5' below grade surface in. borings B-1, B-2 and B-3, <br /> respectively. No hydrocarbon odors were detected during the installation of the three (3)borings. <br /> The subsurface details in each of the three (3) soil borings are shown on the boring logs included <br /> as Figures 4, 5 and 6. <br /> 3.0 CONCLUSIONS <br /> Following are GTI's conclusions based on field observation corroborated by analytical results. <br /> • The subsurface investigation found no evidence of the presence of hydrocarbon <br /> contaminants in the subsurface of the Subject Property. <br /> a The laboratory analysis of the soil samples collected during the subsurface investigation <br /> corroborate field observation and found no evidence of the presence of petroleum <br /> hydrocarbons in the Subject Property's soil. <br /> i <br />
