E <br /> j <br /> 1 c <br /> properly labeled 55-gallon drums. Pugged wato-r :ill be disposed <br /> of at an appropriate facility on the basis o; the .laboratory <br /> analytical results. <br /> -? g.5 WELL SURVEY <br /> The elevation of the top of the well casing will be surveyed with <br /> - a transit and stadia rod and referenced to mean sea level, <br /> - shooting off a known elevation point or suitable permanent refer- <br /> ence point and existing wells. A small notch will be cut in the <br /> top of the well casing to mark the survey point, to ensure that <br /> I this point is used for all future water level measurements. <br /> ! <br /> B.6 GROUNDWATER SAMPLING <br /> . The new•wells will 'be sampled after well development. The other <br /> -- wells will be sampled at the same time. <br /> i <br /> B.6. 1 Sampling Equipment Preparation ! <br /> ! <br /> The well measurement and sampling equipment used will be con- <br /> strutted of inert material whenever possible. Sampling bailers <br /> will be constructed, of. Teflon. Stainless steel pumps will be, i <br /> used to purge the well prior to sampling. All sampling equipment E <br /> dill be sufficiently decontaminated in the following manner prior <br /> § to. introduction. into. each well: is <br /> i <br /> I . Hailers, pumps, suspension rope and lines, and well <br /> sounding tapes will be rinsed thoroughly with clean, <br /> fresh. water to remove dust and dirt. <br /> 2. All equipment will be cleaned inside and. out. The equip f <br /> ment may be cleaned offsite and stored and transported in <br /> i <br /> �. steam-cleaned and protected inert. containers. Nitrile <br /> E gloves will. be worn at all times during sample equipment <br /> cleaning, handling, and sample collection. <br /> F <br /> e42/71050/7 -90/apb B-4 <br /> L <br />
