ARCADIS <br /> Depth to water and depth to bottom measurements were collected with an electrical water indicator. <br /> Depth to water was measured as 36.55 feet bgs with a total depth of 68.88 feet bgs. During the most <br /> recent monitoring and sampling event(fourth quarter 2008)G-R measured depth to water as 35.90 feet <br /> bgs and the depth to bottom as 68.76 feet bgs. The discrepancy of depth to bottom (total depth) <br /> measurements(<1 inch)collected is likely a measurement/rounding error when the well was installed. <br /> Monitoring Well MW-5 <br /> MW-5 is a 4-inch diameter PVC groundwater monitoring well and was installed by Sierra Environmental <br /> Services (Sierra)on August 5, 1990. The monitoring well log provided by Sierra (Attachment 1)indicates <br /> that the total depth of the monitoring well when installed was 69 feet bgs with a screen interval of 49 to 69 <br /> feet bgs. <br /> Inspection Findings <br /> Monitoring well MW-5 is currently unsecured. Although the monitoring well cover was in place, the bolts <br /> appear to be the incorrect length resulting in the cover not being firmly secured to the well box. The well <br /> cover gasket should be replaced in the near future. The monitoring well lock and locking cap should be <br /> replaced as well. pp <br /> 1 <br /> Page: <br /> q�Mwmra 1711 wmmntatmmrespana mtwespo,a cknmimitm'r minq,e W71711e79d« 4/5 <br />
