0 • <br /> ' measured a distance of 20-feet between the western edge of the present-day <br /> Manthey Road white line to the toe of the newly constructed soil berm that <br /> ' surrounds field 52a. The berm width is an additional 13-feet, so the total distance <br /> separating the west edge of Manthey Road and the easternmost edge of field 52a <br /> is 33-feet. The former location of LMW-5 is therefore more than 20 feet east of <br /> ' field 52a. <br /> Based on these reconnaissance efforts, it appears that the eleven former wells <br /> ' and piezometers have been destroyed by farming or construction operations. <br /> Their former sites are now located in developed areas outside the boundaries of <br /> reclaimed water land application areas. Because the former well/piezometer <br /> ' sites are located outside land application areas and beneath roads or graded fill, <br /> there does not appear to be significant potential for the former wells to serve as <br /> direct conduits for reclaimed water to reach deeper groundwater. <br /> ' 3.0 DEVIATIONS FROM APPROVED WORKPLAN <br /> ' There were several deviations from the approved monitoring well installation <br /> workplan. All deviations are considered minor or insignificant, and include the <br /> following. <br /> ' Relocated MWM-11: Pre-existing piezometer P-3 was to be replaced by <br /> MWM-11. However, P-3 was destroyed by construction activities subsequent <br /> ' to workplan approval and before monitoring well installation. Kleinfelder <br /> personnel could not locate the destroyed well, and there was concern that if <br /> installed at its planned location MWM-11 could soon also be destroyed. <br /> ' Monitoring well MWM-11 was therefore located about 500 feet southwest of <br /> the location of P-3. The deviation was presumed acceptable because MWM- <br /> 11's objective is to monitor conditions west of Land Application Area 50. The <br /> ' location for MWM-11 is west of Land Application Area 50. <br /> Additional well MWM-26: An additional well, MWM-26, was installed <br /> ' southeast of MWM-23. When the well installation program was initiated, <br /> construction activities prevented access to the approved location for MWM- <br /> 23. Additionally, there was concern that if MWM-23 were installed it would <br /> t likely be soon destroyed. To establish a replacement monitoring location, <br /> MWM-26 was installed in a developed area as near to the approved location <br /> t for MWM-23 as possible. As a follow-up on July 1 , 2005, MWM-23 was <br /> installed at its approved location; MWM-26 was left in place as insurance <br /> against potential damage to MWM-23 as development proceeds towards <br /> ' completion. Once construction activities have ceased, MWM-26 will be <br /> abandoned and destroyed. A well destruction workplan shall be submitted <br /> to RWQCB staff at least 30-days prior to destruction of MWM-26. Until that <br /> ' time, both MWM-23 and MWM-26 will be employed as part of the monitoring <br /> network. <br /> t <br /> 1 <br />
