' 3.0 FINDINGS <br />' 3.1 GEOLOGIC AND HYDROGEOLOGIC CONDITIONS <br /> Soils beneath the site were investigated to a maximum depth of 26 feet bgs during this investigation In general, <br /> similar lithologic conditions were encountered at each location explored Sandy silts to silty sands were <br />' encountered from the surface to approximately nine feet bgs Silty to clayey peat was encountered to <br /> approximately 15 feet bgs The peat was underlain by fine sand and silt which becomes coarser at approximately <br /> 21 feet bgs <br /> 1 Groundwater was generally encountered from the surface(in the leach fields) to approximately eight feet bgs <br /> on the levees Several borings first encountered groundwater as deep as 13 feet bgs This water may represent <br /> 1 a separate horizon than the perched groundwater found at shallower depths The different depths to groundwater <br /> are likely due to the variable ground surface elevations and fill material <br />' 3.2 SOIL ANALYSIS RESULTS _ <br /> King Island <br /> fWith the exception of boring SB2, soil samples collected from the King Island facility contained no detectable <br /> concentrations of analyzed constituents Concentrations of benzene, toluene, and total xylenes were detected at <br /> 0 16, 0 069, 0 031 ppin respectively in SB2 <br /> Holiday Harbor <br /> Soil samples collected from Holiday Harbor contained no detectable concentrations of analytes <br /> The analytical results for the soil samples collected in January and February are presented in Table 1 Complete <br />' laboratory results and chain-of-custody records are included in Appendix B <br /> 3.3 GROUNDWATER ANALYSIS RESULTS <br />' King Island <br />' Detectable concentrations of TPHg were reported in samples collected from SBI, SB2, S1314, and SB26 <br /> Reported detectable concentrations of TPHg ranged from 51 ug/Q in SB 14 to 240,000 ugIV in SB26, in the <br /> vicinity of the formerly hand angered hole SB10 (RESNA) <br /> Detectable concentrations of TPHd were reported in samples collected from SBI, S132, and SB26 Reported <br /> detectable concentrations of TPHd ranged from 2,200 jcg/P in SBI to 3,000,000 ug/2 in SB2, in the vicinity <br />' of the former fuel pump, in front of the marina store <br /> h rM <br /> 50133-00102 7 <br /> 1 <br />
