GROUNDWATER TECHNOLOGY <br /> STANDARD OPERATING PROCEDURE <br /> CONCERNING SOIL SAMPLE COLLECTION AND <br /> HANDLING WHEN SAMPLING FOR VOLATILE ORGANICS <br /> SOP is <br /> 1. Use a sampling means which maintains the physical <br /> integrity of the samples. The project sampling Protocol <br /> wi11 designate a preferred sampling tool. A split spoon <br /> �* sampler with liners or similar tube sampler which can be <br /> sealed is best. <br /> 3 , ,} *he d;screticn of y^e project manager: the samples <br /> shculd be either. <br /> A. sealed in liner with teflon plugs (The "California <br /> Sampler') or <br /> 3. field prepped for sample analysis. <br /> Projects using method (A) will incur a separate sample <br /> preparaticn charge of S 10.00 per sample in the labora- <br /> s tory. For method {3} , prepared and pre-weighed vials, <br /> ' order at least 2 <br /> and sample coring syringes must be o <br /> weeks ahead of time from the laboratory before sampling,, j <br /> (Vials are free if samples will be sent to Groundwater <br /> Technology Laboratory) . <br /> 3. For sending whole-core samples (2A above) : I <br /> ,- A. Seal ends of liner with teflon. plugs leaving no <br /> free air space inside. <br /> 61 <br /> B. Tape with duct tape. 1 <br /> r � <br /> C. Cover with a non-contaminating sealant. (paraffin) . 1 <br /> D. Place in plastic bag labeled with indelible marker. <br /> Use.
