i Mel k4 KLEINFELDER On November 26, 2003 monitoring well LMW-3 was reported as damaged and later i confirmed during subsequent monitoring events (December 10, 2003; December 16, ' 2003; and January 12, 2004). Monitoring well LMW-3 was first recorded as "Gone" on March 2, 2004, and presumably destroyed by grading and construction activities in the area. The former location of the LMW-3 site was west of and within the shoulder area of Manthey Road and south of what was a driveway for the residence that since has been t demolished. The installation of LMW-3 was constrained at the time by the proximity of Manthey Road to the east and the irrigation ditch aligned parallel with Manthey Road to the west. Historical aerial photographs reviewed from June 2001 shows the turn-out ' area repeatedly used by field personnel conducting monthly water level measuring tasks. I The attached Plate 2 shows the depicted location of LMW-3 on an aerial photograph taken while the well in place. The well head only measured 4-inch by 4-inch square and thus cannot be discerned in this photograph at its present scale. Any increased zoom on the photograph produced less clear results. Presently (August, 2005), the former LMW-3 site is located within the shoulder area (approximately 10-feet to 12-feet west of the ' Manthey Road edge) and has experience extensive re-working during grading operations. The remaining monitoring well casing, if any, is believed to be beneath the graded soil. Plate 1 shows the location of LMW-3 in relation to the current site ' configuration. Monitoring well LMW-5 was last monitored March 30, 2004 and reported as damaged i during subsequent monitoring events on May 27, 2004; June 30, 2004; July 30, 2004; ' and, August 20, 2004. The monitoring well was reported as "Gone' on September 27, 2004. i' Monitoring well LMW-5 was formerly located on the west side of Manthey Road and I approximately 200-feet north of the dirt road driveway which led to the residence noted on Plate 3. The residence has since been demolished, and the soil moving and grading activities have been performed as part of planned development. The monitoring well, which existed at the time of the photograph in Plate 3 (June 2001), cannot be discerned in the photograph. However, a visible turnout located west of Manthey Road delineates ' the general area where LMW-5 was formerly located. The precise location of LMW-5 can be estimated from the following historical facts - the placement of LMW-5 was constrained by Manthey Road to the east, and to the west by farming operations conducted at the time of well installation. Presently (August, 2005), agricultural disposal field 52a is also located west of Manthey Road and in the vicinity of the former monitoring well LMW-5 site. Kleinfelder representatives recently measured a distance of 20-feet between the western edge of the present-day Manthey Road white line to the toe ' of the newly constructed soil berm surrounding the disposal field 52a. The berm width is an additional 13-feet west of Manthey Road. The total distance separating the west edge of Manthey Road and the easternmost edge of Field 52a is therefore 33-feet. tThe estimated location of LMW-5 was approximately 10-feet to 12-feet west of Manthey Road; and therefore outside the agricultural disposal field (approximately 23-feet east of ' field 52a). The shoulder to Manthey Road has experienced reworking with construction activities, and the soil berm constructed for field 52a has likely buried any remnant PVC casing from former monitoring well LMW-5. There are no plans to apply reclaimed water to the estimated location of the former site for LMW-5. ' C20-4099-04.E02/ST05R1057/JDZ:ly Page 3 of 5 ©2005 Kleinfelder,Inc. August 31,2005
