AWL <br /> April 26, 1988 AGS Job No. 2005-P <br /> Delta Truck Sales, Stockton, California <br /> components that are installed in the well will be steam cleaned <br /> immediately before well installation. <br /> The bentonite/cement seal will be allowed to set for at least 24 <br /> hours before well development. The well will be developed using <br /> a surge block and extensive pumping. The ground water will then <br /> be purged until discharged water is essentially clear of <br /> suspended sediments. After the well is developed, the well will <br /> be purged and ground water samples will be collected. Purging <br /> will be conducted using a submersible pump until at least five <br /> well volumes are removed and until stable pH, conductivity, and <br /> temperature readings are obtained. <br /> Samples will be collected by lowering a Teflon bailer, cleaned <br /> with Alconox and rinsed with deionized water, to a point <br /> approximately three feet below the ground-water surface. Sampled <br /> water will be transferred into containers supplied by the <br /> analytical laboratory specifically for the types of analyses to <br /> be performed. Preserving agents will be also be provided by the <br /> f <br /> laboratory. All sample containers will be sealed, labeled and <br /> refrigerated for transport to the laboratory. A Chain of Custody <br /> Record will be initiated by the sampling personnel and will <br /> accompany the samples to the laboratory. <br /> 16 <br /> ADD/led GeoSVWems <br />
