F' FLUOR DANIEL GTI, INC. <br /> f STANDARD OPERATING PROCEDURE <br /> CONCERNING SOIL SAMPLE COLLECTION AND <br /> HANDLING WHEN SAMPLING FOR VOLATILE ORGANICS <br /> SOP 15 I <br /> 1. Use a sampling means which maintains the physical integrity of the samples. The project sampling <br /> protocol will designate a preferred sampling tool. A split spoon sampler with liners, or similar tube <br /> sampler which can be sealed,is best. <br /> 2. The samples should be sealed in the liner,with teflon plugs(The"California Sampler")or plastic caps. <br /> 3. For sending whole-core samples (above): {$}k <br /> I F <br /> A. Seal ends of liner with teflon plugs or plastic caps, leaving no free air space inside. <br /> r <br /> i <br /> B. Tape with duct tape. <br /> C. Label the sample with the following information: sample identification,depth,date and time, <br /> project number and required analyses. <br /> D. Place in plastic bag labeled with indelible marker. Use Well#,depth,date, and job#. <br /> i <br /> 4 <br /> E.- Place inside a second bag and place a labelling tag inside outer bag., <br /> 1 <br /> 1 <br /> F. Enclose samples in a cooler with sufficient ice or dryice to maintain samples at 4 degrees C <br /> during shipment. k <br /> G. Seal cooler with a lock,.or tape with samplers signature so tampering can be detected. <br /> f H. Package cooler in a box with insulating material. Chain of custody forms can be placed in a <br /> plastic bag in this outer box. <br /> I. If dry ice is used, a maximum of 5 pounds is allowed by Federal Express without special <br /> documents(documents are easy to obtain but are not necessary for under 5 pounds). Write <br /> "ORM-A dry ice", " pounds,for research" on outside packaging and on regular airbill <br /> under classification. UPS does not accept dry ice. <br /> t J. Soil cores kept a,.4 degrees C are only viable for up to 7 days when aromatic hydrocarbons <br /> are involved. The lab`should prepare the samples in methanol once in the lab. <br /> 4: Decontamination of equipment in the field requires a detergent wash,with a distilled water rinse. <br /> - I <br /> I <br /> i <br /> f � <br /> 4 <br /> i <br /> t <br />
