advanced via the geoprobe/hydropunch technique. The proposed boring locations are <br /> indicated on Figure 2 of this workplan. Up to three soil samples will be collected from <br /> each boring. <br /> 4) Collect eight random pesticide samples from farm field portions of the subject property. <br /> 5) Collect two sediment samples from the surface water runoff from facilities located south of <br /> the subject property. <br /> 6) Collect one groundwater from the on-site groundwater production well. <br /> 7) Maintain samples under chain-of-custody and transport the samples to a Department of <br /> Health Services (DHS) certified analytical laboratory for chemical analyses. Analyze <br /> select soil and groundwater samples to detect the presence of waste oil and its common <br /> constituents. <br /> 8) Prepare a written report describing the field activities, summarizing the laboratory data, <br /> presenting investigation findings, and providing conclusions and recommendations. <br /> III. FIELD ACTIVITIES <br /> A. Underground Utility Clearing <br /> To avoid damage to underground utility installations during the course of subsurface investigation, <br /> AllWest will mark all drilling locations with a white stake and contact Underground Service <br /> Alert(USA), an organization for public utility information, on the pending subsurface <br /> investigation. USA then will notify each of the public and private entities that maintained <br /> underground utilities at the site to locate and mark their installations for field identification. <br /> A private locator will also be employed by AllWest to conduct a magnetometer sweep of the <br /> investigation area to confirm the marked underground utilities and to locate unmarked utilities, if <br /> any. Proposed sampling points will be relocated if in conflict with the underground utilities. All <br /> final sampling locations will be cleared of known utilities. <br /> B. Soil Sampling Through Geoprobe/Hydropunch <br /> Soil samples will be collected through the geoprobe/hydropunch process at thirteen locations at the <br /> site for field screening, laboratory analyses and/or archiving. In general, soil samples will be <br /> collected at 4, 8 and 12 feet below the ground surface. One of the borings,B-1 will be located by <br /> the above ground gasoline tank; two borings, B-2 and B-3 will be located by the above diesel above <br /> ground tanks; three borings,B-4,B-5, and B-6, will be located in the main storage barn; four <br /> borings,B-7,B-8, B-9 and B-10, will be located in smaller storage sheds and three borings, B-11, <br /> 3 <br />
