rw <br /> GROUNDWATER TECHNOLOGY <br /> STANDARD OPERATING PROCEDURE <br /> CONCERNING SOIL SAMPLE COLLECTION AND <br /> HANDLING WHEN SAMPLING FOR VOLATILE ORGANICS <br /> SOP 15 <br /> 1. Use a sampling means which maintains the physical <br /> Jm integrity of the samples. The project sampling protocol <br /> will designate a preferred sampling tool. A split spoon <br /> sampler with liners or similar tube sampler which can be <br /> sealed is best. <br /> 2. At the di SCreticn o, ?e Project manager,�'_', Ln4a -`*n� a <br /> _ s <br /> should be either, <br /> C , A. sealed in liner with teflon plugs (The "California <br /> 1 � <br /> Sampler") or <br /> B, field prepped for sample analysis. <br /> r <br /> N Projects using method (A) will incur a separate sample i <br /> preparation charge of $ 10.00 .per sample in the labora- <br /> tory. For method (B) , prepared and pre-weighed vials, <br /> and sample coring syringes. must be ordered at least 2 <br /> F weeks ahead of time from the laboratory before sampling. <br /> a (Vials are :Free if samples will be sent to Groundwater <br /> Technology Laboratory). <br /> 3. For sending whole-core samples .(2A above) : K <br /> u� A. Seal ends of liner with teflon plugs leaving. no s <br /> free air space inside. <br /> s <br /> B. Tape with duct _tape. f <br /> C. Cover with. a. non-contaminating sealant (paraffin) . . <br /> r <br /> D. Place in. plastic bag labeled with indelible marker. <br /> Use Well #, depth, date, and job #. <br /> i <br /> E. Place inside a second bag and place a labelling tag <br /> r inside outer bag <br /> F. Enclose samples in :a cooler with sufficient ice or a <br /> } 7 <br /> ( dry ice .to maintain samples at 4 degrees during <br /> shipment. <br /> G. Seal cooler with a lock or tape with samplers 3 <br /> signature so tampering can .be detected. <br /> 1 <br /> GROUNDWATER <br /> ' <br /> EEITECHNOLOGY,INC. <br /> `.
