Report—Soil Boring Installation Page 4 <br /> 2525 Hutchins Road, Lodi <br /> ' Project No. 503.2 <br /> February 14, 2005 <br /> 2.3 Soil and Groundwater Sampling Procedures <br /> ' The soil sample collection procedure was as follows. Prior to commencing the <br /> insertion of a 4 foot section of rod, the push point was retracted to allow sample <br /> ' material to enter the soil sample barrel. Upon retrieval of the sampling device, <br /> the plastic sample sleeve is pushed out of the sampling barrel. After <br /> examination of the sample sleeve, the ends of the sleeve were sealed using <br /> ' plastic end caps. Since no field evidence of soil contamination was found, the <br /> samples were not submitted for laboratory analysis. <br /> ' After reaching total depth, the boring was converted to a temporary well by <br /> lowering a string of % inch diameter flush-joint PVC casing into the boring. The <br /> bottom 5 feet of the casing was screened to allow groundwater to enter the <br /> ' boring. A small-diameter stainless steel bailer was then lowered down the <br /> casing and a sample of the groundwater was recovered. Upon recovery, the <br /> water contained in the bailer was carefully transferred to sample containers <br /> ' supplied by the analytical laboratory. During the transfer care was taken to <br /> minimize turbulence or agitation. Upon collection, the groundwater sample <br /> ' containers were sealed, labeled and placed into an ice chest chilled to 4 degrees <br /> C. for shipment. The bailer was steam cleaned prior to use. The groundwater <br /> sample was transported under Chain-of-Custody protocol to Argon Labs (DHS <br /> ' #2359), of Ceres California, for analysis. <br /> 1 <br /> 1 <br /> t2937 Veneman Ave.,#B240 Geo-Phase Ear ironmenlal Inc.
