' 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 Iithologic 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 /> Groundwater was generally encountered from the surface(in the leach fields to approximately PP xunately a:ght feet bgs <br /> on the levees. Several borings first encountered groundwater as deep as 13 feet bgs. This water may represent <br /> ' 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 /> With 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 ppm respectively in SB2_ <br /> Holiday Harbor <br /> ' SoiI 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, SB14, and S1326. <br /> Reported detectable concentrations of TPHg ranged from 51 Ag/P in SB 14 to 240,000 uglQ in SB26, in the <br /> vicinity of the formerly hand augered hole SB IO(RFSNA). <br /> Detectable concentrations of TPHd were reported in samples collected from SBI, SB2, and SB26. Reported <br /> detectable concentrations of TPHd ranged from 2,200 jtg12 in SBI to 3,000,000 mg11 in SB2, in the vicinity <br /> ' of the former fuel pump, in front of the marina store. <br /> h;4aeueclloLhlloidu i.rpt <br />
