The project sampling protocol willntegrity <br /> - designate a preferred sampling tool. A split-spoon <br /> with liners, or siDilar tube sampler which can by ssampler <br /> ealed, is <br /> _ best. <br /> 2. At the discretion of the project manager, the samples should <br /> be either. <br /> A. Sealed in liner with TeflonR plugs (The "California <br /> Sampler”) or <br /> 7 E• Field-prepped for sample analysis. <br /> Projects using method "A11 will incur a separate sample <br /> prepardtion"charge of $10.00 per sample in the laboratory. <br /> , <br /> For methal B , prepared and pre-weighed vials, and sample- <br /> coring syringes must be ordered at least two weeks ahead of <br /> time from the laboratory before sampling. (Vials are free <br /> if samples will be sent to Groundwater Technology <br /> Laboratory) . . <br /> 3. <br /> For sending Whole-core samples (2A above) : <br /> A. Seal ends of liner with TeflonR tape or aluminum foil <br /> leaving no free air space inside. <br /> B. Tape with duct tape. <br /> C. Place in plastic bag labeled with indelible marker. <br /> Use well number, depth, date, and job number. <br /> mber. <br /> D. Place inside a second bag and place a labelling tag <br /> t inside outer bag. <br /> E. Enclose samples in a cooler with sufficient ice or dry <br /> ice to maintain samples at 4 celsius during shipment. <br /> F. Seal cooler with a lock or tape with samplers' <br /> signature so tampering can be detected. <br /> E <br /> .a GHOI'\DWATEH <br /> TECHVIIJKA:INC, <br /> 1 <br /> 1 <br />
