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 /> 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 discretion of the project manager, the samples <br /> should be either . <br /> A. sealed in liner with teflon plugs (The "Caiifornia <br /> Sampler" ) or k> <br /> B. field prepped for sample analysis. <br /> r <br /> i <br /> Projects using method (A) will incur a separate ;;'sample <br /> preparation charge of $ 10. 00 per sample in theJlabora- <br /> tory. For method (B) , prepared and pre-weighed : <br /> vials , <br /> and sample coring syringes must be ordered at least 2 <br /> weeks ahead of time from the: laboratory before sampling. P <br /> (Vials are free if samples will be sent to Groundwater <br /> Technology Laboratory) . <br /> 3 . For sending whole-core samples ( 2A above ) ; <br /> A. Seal ends of liner with: teflon plugs leaving no 6!� <br /> free air space inside. <br /> B. Tape with duct tape. <br /> rt <br /> C. Cover with a non-contaminating sealant (paraffin ) . <br /> D. Place in plastic bag labeled with indelible' marker, i:" <br /> Use Well 0', depth, date; .and job # . j <br /> E. Place inside a second bag and place a labelling tag <br /> inside outer bag. <br /> F <br /> i <br /> F. Enclose samples in a cooler with sufficient ice or <br /> dry ice to maintain samples at 4 degrees during <br /> shipment. Is <br /> 1 <br /> G. Seal cooler with a lock„ or tape with samplers <br /> signature so tampering can be detected, <br /> H. Package cooler in a boxiwith insulating material. <br /> Chain of custody forms can be placed in a plastic <br /> bag in this outer box. I:a <br /> s <br />
