4.5 Deep Soil Boring <br /> A deep soil boring(P1)was drilled under the base of the existing septic pit in the southeastern <br /> corner of the motel property by V&W Drilling Inc. (V&W)under PHSEHD permit using a <br /> Geoprobe on May 3,2006. The soil boring was inclined to a 30%angle from vertical so as to <br /> intercept the base of the septic pit at a distance of about 1 foot below the base of the pit. <br /> Continuous core plastic sleeves were used to collect a sample. A Mini-Rae 2000 photo <br /> ionization device(PID)was used to monitor soil gas for volatile organic compounds. All <br /> readings on the PID were in the range of 0 to 2 ppmv which is considered as background. <br /> The soil column penetrated was comprised entirely of brown silty clay that was moist. Gravel <br /> clasts were recovered that indicated that the gravel pack of the base of the septic disposal pit had <br /> been countered at a depth of 25 feet vertical bgs. Immediately after drilling out of the gravel <br /> clasts a single soil sample(P1-26 ) was collected using the continuous core system by the <br /> geoprobe. This sample was placed on ice in accordance with the workplan until the <br /> GeoAnalytical personnel took possession of the sample under chain of custody procedures. <br /> The following constituents were reported to be present from GeoAnalytical Laboratories Report <br /> #S6E0309 from soil sample P 1-26. <br /> Analyte Method Reporting Limit Analytical Result <br /> Iodine USEPA 345.1M 2 mg/kg Below analytical method <br /> detection limit <br /> pH USEPA 9045 NA 8.1 units <br /> Chloride USEPA 300.0 10 mg/kg 14 mg/kg <br /> Motor Oil USEPA 8015M 10 mg/kg Below analytical method <br /> detection limits <br /> Diesel USEPA 8015M 1 mg/kg Below analytical method <br /> detection limits <br /> Kerosene USEPA 8015M 1 mg/kg Below analytical method <br /> detection limits <br /> Gasoline USEPA 8015M 1 mg/kg Below analytical method <br /> detection limits Analytical <br /> A full-scan USEPA Test Method 8260B analysis of soil sample L2-13.0 was reported to contain <br /> below analytical method detection limits for all analytes. None of these concentrations were <br /> found to be considered as hazardous waste under definition of California or federal definitions. <br /> Main\Environmental\St.FrancisMoteNteport\Report05252006.wpd 16 <br />
