i <br /> L <br /> L <br /> 3.0 SCOPE OF WORK AND INVESTIGATION PROCEDURES <br /> L <br /> The scope of work completed during the investigation included the advancement of three soil <br /> borings, the collection of ground water samples using a Hydropunch' (HP) sampling device, <br /> and the collection of soil samples for lithologic description, laboratory analysis and <br /> photoionization detector (PID) screening. Photographs of the field investigation are included <br /> in Appendix A. The investigation was conducted in general accordance with the Workplan <br /> with the following exceptions: <br /> I <br /> * Soil borings were completed to an average depth of 19 feet below <br /> i <br /> ground surface (bgs) (where ground water was first encountered), <br /> Linstead of the anticipated depth of 45 feet bgs. <br /> L * Soil samples for laboratory analysis were collected with a California- <br /> Modified, split-spoon sampler lined with brass tubes. It was initially <br /> Lproposed that samples would be collected directly from the core-barrel <br /> and placed into glass jars. <br /> Select samples were analyzed for total petroleum.hydrocarbons as <br /> Lgasoline (TPH-G) in addition to TPH as diesel (TPH-D) as was initially <br /> Lproposed. <br /> 3.1 Boring Installation <br /> L 7i <br /> On March 23, 1997, three soil borings (SB-01 through SB-03) were drilled at the Property <br /> by Spectrum Exploration Inc., of Stockton, California. Soil boring locations are shown on <br /> I <br /> LFigure 2. The soil borings were drilled using a truck-mounted drill rig equipped with 8-inch <br /> outside diameter, hollow-stem augers. The soil borings were completed to depths ranging <br /> L 809-001 rpt/04-18-97/u/kedata/reP ons 5 <br /> Y <br /> L TerraNext <br />
