ENGEO INCORPORATED Sample Handling and Shipment All samples for laboratory analyses will be chilled to 4 degrees Centigrade in the field, during shipment, and in the laboratory. The sample containers will be placed in chilled coolers immediately following collection and kept cool with ice prior to and during shipment. All samples collected at the site are considered environmental samples; they are not known to contain hazardous levels of contaminants and may be shipped to the laboratory accordingly. Each of the sample bottles will be sealed and labeled as follows: bottle labels will contain all required information including sample number, time, and date of collection, analysis requested, sampler's name and preservatives used, if any. Sealed bottles will be placed inside polyethylene Ziploc bags. The bagged bottles will be packed in large coolers, padded with an absorbent material, such as vermiculite, and chilled with ice contained in Ziploc bags. All sample documents will be affixed to the underside of each cooler lid. Samples with restrictive holding times will be shipped within 24 hours following collection, usually on the same day for volatiles analysis. Samples collected late in the day will be shipped the following day. Advance coordination with the laboratory will be required for any shipments on Friday. Samples without holding times will be held until the next critical shipment is ready in order to reduce shipping and handling costs. Chain-of-custody procedures will be used to document the handling and processing of all samples from the time of collection until they are destroyed. Each shipment of samples will be accompanied by a chain-of-custody record which documents all aspects concerning the time of collection, method of shipment, analysis requested, etc., for each sample. This written record may become important if the results of any analysis are used in litigation. A sample 4943.4.640.01 April 17, 2007 12
