Proposed Work Plan November 4, 1988 <br /> U.S.A. Petroleum Station No. 65, Lodi, California AGS 87050-3 <br /> 7) Evaluate the local ground-water gradient by surveying the <br /> top of each well casing, measuring static ground-water <br /> levels in the wells, and calculating the relative elevation <br /> of the ground-water surface in each well. <br /> 8) Perform a bailer test on onsite monitoring wells to obtain <br /> initial estimates of aquifer characteristics. This <br /> information is necessary to comply with reporting <br /> requirements for a Problem Assessment Report. <br /> 9) Install additional offsite monitoring wells, if necessary, <br /> to adequately delineate the extent of subsurface <br /> contamination. <br /> 10) Prepare a Problem Assessment Report summarizing our <br /> findings, conclusions, and recommendations. The report will <br /> meet the reporting requirements of the CRWQCB, Central <br /> Valley Region. <br /> Well MW-4 will be located in Lower Sacramento Road east of the <br /> Woodridge Irrigation District Canal. The location will be <br /> lateral to and downgradient from the underground tanks. Well MW- <br /> 4 will be used to help evaluate the lateral extent of <br /> contamination in the inferred downgradient direction from the <br /> tanks. Previously measured directions of ground-water flow at <br /> the site have been south 40 degrees east and south 35 degrees <br /> east. These measured values are based on data collected <br /> approximately one year apart. Well MW-5 will also be located in <br /> Lower Sacramento Road east of the Woodridge Irrigation District <br /> Canal . This well will be located in a direction downgradient <br /> from the underground tanks and will be used to evaluate the <br /> 6 <br />`� Applied GeoSystems <br />
