Report—Soil Boring Installation Page 5 <br /> 2525 Hutchins Road, Lodi <br /> ' Project No. 503.2 <br /> February 14, 2005 <br /> 3.0 FIELD & ANALYTICAL DATA <br /> ' 3.1 Site Geology and Hydrology <br /> ' Site Geology Observed During Investigation <br /> A detailed log was made of the boring. The information noted includes such data <br /> ' as sample depths, horizons of detectable contamination (detected by field <br /> methods), soil classification utilizing the Unified Soil Classification System and <br /> sediment description (color, texture, composition, hardness, moisture content, <br /> ' and post-depositional changes that have occurred in the sediments). In this case <br /> no field evidence of soil contamination was observed. <br /> ' The shallow soil encountered during the investigation can broadly be <br /> characterized as native (undisturbed) sands and silt. The following is an <br /> ' interpretation of the soils observed during the investigation. A copy of the <br /> boring log is included in Appendix B. <br /> ' Soil Boring B-1 <br /> 0 to 35'Below Ground Surface (BGS) <br /> The soil in this interval generally consisted of silt with varying amounts of sand, <br /> yellowish brown in color. No unusual odors or other evidence of contamination <br /> were noted from the interval. <br /> ' 35'+ to -44'BGS <br /> The soil from this interval consisted generally of yellowish brown, poorly sorted <br /> sand and silty sand. No unusual odors or other evidence of contamination were <br /> ' noted from this interval. <br /> 44'+ to-76'BGS <br /> ' No soil samples were collected in this interval to inability to release the push <br /> point in the sample barrel. <br /> ' Groundwater was encountered approximately 68 feet below grade, and the Total <br /> Depth was 76 feet. <br /> 3.2 Water Sample Analysis <br /> The groundwater sample from the soil boring was submitted for analysis at a <br /> ' California State Certified Laboratory (Argon Labs in Ceres, DHS #2359). The <br /> sample was analyzed for a variety of Volatile Organic Compounds by EPA <br /> method 8260. In general the detection limit for each chemical was 0.5 <br /> ' micrograms per liter (pg/L). <br /> ' 2937 Veneman Ave.,413240 Geo-Phase Environmental Inc.
