(constituents analyzed will be the same as those for the Hydro- Punch samples) . The results of the chemical analysis will determine whether the drill cuttings can be used for inert fill or require remediation. Auger flights will be steam cleaned and soil sampling equipment decontaminated in the same manner described in the Phase I portion of the work plan. Each monitoring well will have a surge block run past the perforated interval for a minimum of 15 minutes and will be developed by a combination of bailing and pumping. All purge water will be contained within labeled 55 gallon drums until results of composite samples from each drum are obtained (same constituents analyzed as Hydro-Punch samples) . Top of casing elevations, in relation to mean sea level, for the wells will be measured by a California licensed surveyor. Upon completion of the well installation, a sample will be obtained from each well in place at the site including the three which were installed in September of 1988. Before a sample is obtained, at least three well casing volumes will be purged and pH/conductivity measurements will be allowed to stabilize within 50 of prior measurement values to ensure that a representative sample is taken. The sample bottles will be filled in a manner which minimizes agitation so that volatilization of affected constituents does not occur. Purge water from well sampling activities will be contained within labeled 55 gallon drums. Composite samples from each drum will be analyzed for the same constituents as the Hydro-Punch samples. Samples will be stored in an iced cooler prior to their delivery to a state certified laboratory. All sampling equipment will be decontaminated in the same manner that the sampling equipment used in the drilling process is. Laboratory analysis of the groundwater samples will consist of the same constituents and analysis to be performed for the Hydro-Punch samples. During each round of groundwater sampling, including the Phase I activities, field blanks and laboratory duplicates will be collected so that the integrity of sample collection and analysis methods can be gauged. Phase III: Aquifer Analysis Hydraulic testing of a minimum of five of the monitoring wells installed at the site will occur so that values for transmissivity and hydraulic conductivity can be obtained. This information will be used to assist in the risk assessment and possible remedial action evaluation to be performed following the completion of the field investigation. The slug tests to be performed at the Stockton Scavenger facility will consist of inserting a "slug" into each well to create an nstantaneous change in water level. A 1-inch diameter slug, which 5
