ATC Associates Inc. <br /> Quality Assurance/Quality Control Plan <br /> Revised November 2002 <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 chemical <br /> ice. The samples will be delivered to a state certified laboratory following under chain-of- <br /> custody protocol within 48 hours of sampling,whenever possible. <br /> Soil in the uppermost brass tube will be described according to ASTM standard practice for <br /> description and identification of soils (ASTM D-2488-84). Stratigraphic, genetic and other <br /> data/interpretations will also be recorded. Soil properties may also be determined from the <br /> middle brass tube and from the sampler shoe. Alternatively the second sample tube may be <br /> used with the uppermost tube for preparation of duplicates. These field observations will be <br /> 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 each <br /> 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:\adrnin\sheils\qaqc-02.doc <br /> 11 <br />
