R <br /> in the soil sample collected at the groundwater interface. MTBE was detected in only one <br /> boring, SB2, by EPA method 8020. However, MTBE was not detected in the SB2 sample by <br /> EPA method 8260 as a confirmation indicatingthis may be a false <br /> y positive result. <br /> r.. As part of the analysis of soil samples. for geophysical parameters, soil samples from borings <br /> SB3 and SB6 were analyzed for percent organic matter (carbon), nitrogen and phosphorus. <br /> Results indicate percent organic matter ranging from 19 percent (SB3-8.5) to 23 percent (S136- <br /> 14.5), nitrogen ranging from 0.009 percent (SB6-15) to 0.02 percent (SB3-8.5), and <br /> phosphorus ranging from 0.005 percent (SB3-8.5) to 0.05 percent (SB6-14.5 and 15). <br /> Carbon:nitrogen:phosphorus ratios were not able to be calculated by the laboratory due to the <br /> large difference in magnitude between the percent organic content and nitrogen and <br /> phosphorus. However, carbon:nitrogen, carbon:phosphorus, and nitrogen:phosphorus ratios <br /> were calculated and are presented in the laboratory reports located in Appendix III. The pH of <br /> �. these,soil samples ranged from 8.01 to 8.12. Table 1 summarizes soil analytical results. <br /> Laboratory reports and chain of custody documentation for soil samples are included in <br /> Appendix III. <br /> In addition, the results from laboratory analysis of soil samples for falling head permeability, <br /> v percent moisture, porosity and dry bulk density are as follows. Soil samples from borings SBI <br /> and SB3 at depths of 2 to 4 feet bgs, 11 to 12 feet bgs, and 15.5 to 16 feet bgs were analyzed <br /> +- for the above parameters. The 2 to 4 foot sample was analyzed as a vadose zone sample and <br /> the 11 to 12 foot and 15.5 to 16 foot samples were analyzed as saturated zone samples. For <br /> �. the vadose zone sample, effective porosity was 33.0%, moisture content was 19.0%, native <br /> state effective permeability to air was 0.396 millidarcy, and the native state effective air <br /> conductivity was 3.27 x 10-5 centimeters per second (cm/s) (vertical). For the 11 to 12 foot <br /> saturated zone sample effective porosity was 36.0%, moisture content was 19.3%, native state <br /> effective permeability to water was 0.443 millidarcy, and the native state effective water <br /> conductivity was 4.55 x 10-7 cm/s (horizontal). For the 15.5 to 16 foot saturated zone sample <br /> effective porosity was 41.1%, moisture content was 18.7%, native state effective permeability <br /> to water was 1,473 millidarcy, and the native state effective water conductivity was 1.51 x 10.3 <br /> cm/s (horizontal). Further discussion of these results is presented in Section 6.0. Laboratory <br /> �., reports and chain of custody documentation for soil samples are included in Appendix III. <br /> wA95122TIumerpt 7 <br /> in <br /> • <br /> SMTN <br />
