U3/ZU/ZUU6 14:53 FAX 75U 942 5ZU6 OUDEK & ASSMIATES lf/.JUU4/UUb <br /> Destruction of Groundwater Wells KS-7 and KI-7 <br /> Prior to well destruction,a Tri-bock will be removed from the well KS-7 and a dedicated <br /> submersible pump will be removed from the well KI-7. 'Wells KS-7 and KI-7 will be <br /> destroyed by removing the top 1.5-feet from each well. Well KS-7 and KI-7 will then be <br /> pressure grouted(20-40 psi)with a tremie pipe outfitted with a rubber gasket at the end <br /> of the pipe. The tremie pipe will pump neat cement down the well until the well casing <br /> and filter pack pore space is filled with neat cement. Dudek estimates approximately 15 <br /> cu-ft of neat cement will be needed to decommission well KS-7 and approximately 20 cu- <br /> ft of neat cement to decommission well KI-7. <br /> Table 1. Well Backfill Volumes <br /> Well Casing Filter Pack Pore Total <br /> Well ID Volume cu-ft) Volume(cu±) Volume <br /> KS-7 7.4 7.7 15.1 <br /> KI-7 10.7 9.6 20.4 <br /> A hole will be excavated approximately one-foot larger in diameter than the original <br /> drilled borehole and to a depth not less than 1.5-feet below ground surface. For example <br /> the excavation around well KS-7 will be at least 22-inches in diameter and the excavation <br /> around well KI-7 will be at least 28-inches in diameter. A six-inch thick mushroom cap <br /> will be installed above the destroyed monitor wells. The excavated hole will be repaired <br /> following San Joaquin County Department of Public Works Department's R-29 Trench <br /> Standard(Appendix C). Waste generated on site will be stored in labeled 55-gallon <br /> drums and disposed of at proper disposal or recycling facility. The concrete/asphalt <br /> repair will be inspected by the San Joaquin County Department of Public Works <br /> Department. <br /> If you have any questions, or require further discussion,please contact me at(760)479- <br /> 4131. �°- <br /> �QOFE Ip <br /> Sincerely, <br /> Dudek&Associates,Inc. <br /> rn <br /> Na MM2SON <br /> m <br /> Derek Reed, P.E. k ICG <br /> C10- `r <br />
