' k`1 KLEINFELDER <br /> To minimize cross-contamination, all developing and sampling equipment will be steam <br /> cleaned prior to use in each monitoring well. Water removed from the wells during <br /> ' purging will be containerized and stored on site pending results of water analyses. <br /> ' The five samples submitted to the laboratory will be analyzed for halogenated volatile <br /> organics by EPA Method 601. <br /> ' 3.4 MONITORING WELL ELEVATION SURVEY <br /> ' The relative elevations of the top of the 4-inch PVC casings will be surveyed for the three <br /> wells. The casing elevations will be tied into an assumed elevation, or a nearby county or <br /> ' USGS benchmark. Depth to the static ground water table will be measured from the top of <br /> each PVC casing. The depth to water will then be subtracted from the elevation of the top <br /> ' of the well casing to provide a water table elevation for each monitoring well location. The <br /> ground water flow direction will then be estimated from the measured water table <br /> ' elevations. <br /> 1 <br /> 1 <br /> 129-88-1378 6 <br />
