is <br />L <br />I <br />1 <br />profile within the surface vegetation's root depth can store approxi- <br />mately 4 inches of moisture. This storage capacity can be achieved by <br />the planned site cover soil profile. According to the water balance <br />evaluation, the cover soil should preclude precipitation infiltrating <br />into the refuse after the placement of final cover. The results of <br />the water balance evaluation for the site are shown on Table 3. <br />GROUND -WATER MONITORING <br />A combined Subchapter 15 and SWAT Proposal has been prepared for sub- <br />mittal to the RWQCB. The proposed ground -water monitoring plan may be <br />revised before approval by the RWQCB and implementation by the County <br />of San Joaquin. <br />The same monitoring well network will be used for the proposed Solid <br />Waste Assessment Test (SWAT) and the Subchapter 15 ground -water moni- <br />toring program. This network consists of three wells to monitor the <br />deep regional aquifer and two wells to monitor a suspected shallow <br />perched zone. Existing Well MW -1 will be incorporated into the pro- <br />gram as a deep downgradient well. Two additional deep (approximately <br />250 to 300 feet) ground -water monitoring wells will be installed: one <br />upgradient (MW -2) and one downgradient (MW -3) from the landfill. To <br />confirm the presence of a shallow perched zone in the Corcoran Clay, <br />two shallow (approximately 30 to 35 feet) wells (MW -4 and MW -5) will <br />be installed adjacent to the two deep downgradient wells. Well MW -2 <br />will function as the deep background water -quality well, while <br />Wells MW -1, MW -3, MW -4, and MW -5 will function as point -of -compliance <br />wells. <br />PJ9 9390310.00D 11 <br />rmtnn Gcenrin�ne <br />
