STANDARD OPERATING PROCEDURE <br /> CONCERNING SOIL SAMPLE COLLECTION AND <br /> ANDLING G M!N SAMPLING FOR VOLATILE ORGANICS <br /> BROP is <br /> 1. Use a sampling mean, which maintains the physical integrity <br /> of the samples. The project :sampling protocol will <br /> �- designate as preferred sampling tool. A split-spoon sampler <br /> with liners, or similar tube sampler which can be sealed, 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 /> B. Field-prepped for sample analysis. <br /> !- Projects using method "A" will incur a separate sample <br /> preparation"$charge of $10.00 per sample in the laboratory. <br /> For method , prepared and pre-weighed vials, and sample- <br /> coring syringes must be ordered at least two weeks ahead of <br /> time from the laboratory beforesampling. (Vials are free <br /> if samples will be sent to Groundwater Technology <br /> �. Laboratory) . <br /> 3. 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 /> D. Place inside a second bag and place a labelling tag <br /> inside outer bag. <br /> E. Enclose samples in a cooler with sufficient ice or dry <br /> • ti: <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 /> Guot,%I ATE:k <br /> TECHm ti.,jo.I%L" <br /> la <br />
