t <br /> it <br /> LEVI N E•FRICKE <br /> 3.0 SCOPE OF WORK <br /> Six tasks are proposed to conduct this investigation, as follows: <br /> Task 1: Permit Acquisition <br /> Task 2 : Well Installation <br /> Task 3 : Well Development and Ground-Water Sampling <br /> Task 4: Laboratory Analyses <br /> Task 5: Data Evaluation and ReportjPreparation <br /> Task 6: Project Management and Meetings <br /> These tasks are described in detaillbelow. <br /> Task 1: Permit Acquisition <br /> It is necessary to obtain a permit from the San Joaquin Local <br /> Health District (SJLHD) to drill ground-water monitoring wells in <br /> San Joaquin County. Included in this task is Levine-Fricke time <br /> for preparing the permit application and interfacing with the <br /> SJLHD, SJLHD permit fees and charges for accelerated review, and <br /> SJLHD charges for field inspection of well grouting. <br /> Task 2: Well Installation <br /> Levine-Fricke will subcontract a well driller for drilling and <br /> installation of the wells. Four shallow (approximately 20-foot <br /> deep) wells are anticipated to be installed, at the locations <br /> shown on Figure 3 . The wells will be drilled with a hollow-stem <br /> auger rig and will consist of 2-incl diameter Schedule-40 PVC. <br /> The bottom 10 feet of the well will be screened with <br /> factory-milled 0.20-inch slots. The slotted section of well <br /> casing will be surrounded with Monterey #3 sand or equivalent. A <br /> 1-foot thick bentonite seal will be set above the slotted <br /> section. The upper blank section of the well casing will be <br /> surrounded with cement grout containing a maximum 4 percent <br /> bentonite. A locking top will be placed at the surface of the <br /> well. <br /> During drilling of the wells, soil samples will be collected at <br /> minimum 5-foot intervals. The samples will be screened for the <br /> possible presence of petroleum using a photo--ionization detector <br /> (PID) . The drilling and soil sampling equipment will be <br /> steam-cleaned between wells. No petroleum-based lubricants will <br /> be used on the augers or samplers. iSoil cuttings will be <br /> contained on the Site pending receipt of laboratory results, at <br /> which time disposal options will be evaluated. <br /> Task 3 : Well 3 : Well Development and GroundLwater_Samplingand GroundLwater_Sampling <br /> After the wells have been installed� and the grout has set, the <br /> wells will be developed and sampled'. Prior to sampling, the well <br /> -2- <br />
