ATC Associates Inc. <br /> Quality Assurance/Quality Control Plan <br /> Revised November 2002 <br /> aluminum foil or teflon tape and plastic end caps, taped and labeled with the following <br /> information: <br /> ✓ date and time <br /> ✓ project ID <br /> ✓ sample ID <br /> ✓ name of sampler <br /> ✓ type of analysis to be performed <br /> This sample will be immediately placed into a cooler containing dry ice or frozen <br /> chemical ice. The samples will be delivered to a state certified laboratory following <br /> under chain-of-custody protocol within 48 hours of sampling, whenever possible. <br /> Soil in the uppermost brass tube will be described according to ASTM standard practice <br /> for description and identification of soils (ASTM D-2488-84). Stratigraphic, genetic and <br /> other data/interpretations will also be recorded. Soil properties may also be determined <br /> from the middle brass tube and from the sampler shoe. Alternatively the second sample <br /> tube may be used with the uppermost tube for preparation of duplicates. These field <br /> observations will be noted on a log prepared for each boring/well. <br /> During sampling, latex or nitrile gloves will be worn to prevent cross-contamination with <br /> other samples. The disposable gloves will be discarded after collecting samples from <br /> each 18-inch sample drive. <br /> Soil samples will be collected at approximately 5-foot intervals, at significant changes in <br /> lithology and intervals of obvious contamination in order to develop a complete profile of <br /> soil contamination. <br /> w:\admin\shel ls\gagc-02.doe <br /> 11 <br />
