Excavated soil will be ` <br /> stockpiled as far to the back of the property as possible, and kept covered to <br /> minimize nuisance conditions such as odors and dust or transported from the <br /> site. <br /> Task 3 Backfill the excavation with clean imported fill. Backfilling will be brought <br /> I to grade and sufficiently compacted to allow for automobile traffic and future r <br /> resurfacing. WeAPI <br /> 1 <br /> Task 4 Dispose of the excavated soil in an acceptable landfill as soon as possible, <br /> hopefully the day of excavation. Horizon assumes that the soil will be <br /> disposed of at BFI's Class II landfill in Livermore, California. <br /> Task'5 Resurface the excavation the following weekend so that the surface is suitable <br /> for traffic by Monday morning. <br /> Task 6 Drill two soil borings and install, develop, survey, and sample two additional <br /> groundwater monitoring wells (MW-4 and MW-5) in the borings at the <br /> I locations shown on Figure 2. The borings will be drilled and sampled as <br /> described in Attachment A. The wells will be installed a minimum of ten feet <br /> below groundwater.. A typical monitoring well construction diagram for this <br /> site is shown on Figure 3. Well locations have been selected in areas that will <br /> provide groundwater data upgradient and downgradient (based on the most <br /> recently reported groundwater data) of the known gasoline source area. <br /> Groundwater level measurements will be taken in the new and previously <br /> existing site wells for groundwater gradient evaluation. <br /> 3001-11.wp 5 HORIZON ENVIRONMENTAL INC. <br />
