mom <br /> AlAll <br /> KLEINFELDER <br /> 3.5 WATER SAMPLE ANALYSES AND RESULTS <br /> Three ground water samples and an equipment blank sample were delivered <br /> under chain-of-custody to Chemwest Analytical Laborator3.as, Inc., in <br /> ti <br /> Sacramento. The three ground water samples were analyzed for total <br /> 1 � petroleum hydrocarbons extractable by GC-FID and volatile aromatic <br /> compounds (benzene, toluene, ethyl benzene, xylene, IBTXEI ) by EPA Method <br /> 1 i <br /> i 502. All constituents in the three samples were below laboratory <br /> f � a <br /> s reporting limits. Laboratory data sheets and chain-of--custody forms are <br /> &: included in Appendix B. The equipment blank sample was not analyzed. <br /> r <br /> is 3.6 MONITORING WELL ELEVATION SURVEY <br /> rte! The relative elevations of the top of'the 2-inch PVC casings were surveyed <br /> by Associated Land Consultants, R.C.E. LS4268. The casingr.elevations for <br /> n.. <br /> i <br /> ea <br /> the three wells are tied into :a USGS mean s ;lPLez elevation benchmark. <br /> syrA <br /> iThe: tog of the casing was. generally set. 3 feet above the ground surface. <br /> r <br /> i The depth` of the static .ground water was measu_�eG from a set location at <br /> the: top ,of each PVC casing The <br /> depth to water was subtracted from the <br /> elevation ;of the top of the well . casing to provide aground water <br /> a elevation for each monitoring well location— The well'.elevations, depth <br /> to ..wafer .measurement's, and a <br /> calculated ground water elevations re listed <br /> on Table: 1. <br /> :.: The g_`ound water elevations for eacn monitoring ;,rsAZ locatio n-inwatt a <br /> ground water flow . direction' to the nortx The ground_ er able t; <br /> ,. t <br /> M}.
