The proper method of disposal will be <br /> dependent upon results of laboratory analysisthis disposal will be the <br /> responsibility of the client unless other arrangements have been made. <br /> j Well Construction <br /> l All materials used in well construction will be thoroughly cleaned prior to <br /> introduction into the boring. A bentonite or cement and bentonite grout will be <br /> placed at the bottom of the boring as necessary. After the seal has been allowed <br /> to set long enough to support the weight of the casing, a 4-inch diameter well <br /> casing (stainless steel or PVC) with end cap and factory perforations for <br /> placement in the saturated zone (taking into account seasonal variation) will be <br /> placed in the boring. The screen and filter pack sizes will be as noted in the <br /> well construction drawing. The casing and end caps will be threaded or joined <br /> by stainless steel screws; 110 pVC cement will be used. The filter pack will <br /> extend two feet above the perforated zone.

The water produced during well <br /> development will be containerized and left on-site in 55-gallon drums or other <br /> suitable containers for disposal as hazardous waste if deemed necessary upon <br /> onsiility of the 1 receipt of laboratory results. <br /> thave Disposal <br /> en will be <br /> The wells l wiibbe allowed tent <br /> unless other arrangements <br /> stabilize for twenty-four(24) hours prior to sampling. <br /> All soil and ground water samples will be properly labeled with date collected, <br /> project number, sample coordinator, and sample identification. Field records <br /> will document the above information and other significant data, such as names <br /> of on-site personnel, sampling methods, date and timc of sampling, the number <br /> fiber <br /> _ of well volumes removed before sampling, Preservatives added(if any), y <br /> filtration performed-on samples. - <br />
