* µ . SEIM- i r Coca-Cola Enterprises-West r . Job No.90054.02 '- glass vials with Teflon@ septum caps and into one 1-liter amber glass bottle. The VOA vials were filled,capped,and inverted to check for possible air bubbles. if air bubbles were present, the vials were refilled and checked again. This procedure was repeated until an acceptable sample was obtained. The containers were filled until there was no head space remaining in the t bottle. One field method blank sample was collected using distilled water pourer into the decontaminated sample bailer after the final rinse and poured directly into the sample collection ..« containers. Also,a trip blank sample was carried in the sample container from origin to final j 3 destination. The field method and trip blank samples are part of USTEC's QA/QC plan for a, proper sampling and equipment decontamination. After filling each designated container,all groundwater sample and field method blank vials and jars were then labeled,wrapped in a protective wrap,double bagged in plastic bags and placed on ice and maintained at about 4°Centigrade to minimize potential volatilization of the organic ;,. compounds. Chain-of-custody documentation was maintained by USTEC personnel and r accompanied the groundwater samples until delivery to Sequoia Analytical in Redwood City, F California. Sequoia Analytical is a California State certified laboratory. The chain-of-custody rT documentation is presented in Appendix A. is The Teflon® bailer was decontaminated prior to entering the site and was decontaminated between samples to prevent potential cross-contamination of the samples. Specific decontamination procedures for all sampling equipment included washing in a soap/tap waver solution followed by a tap water rinse and two distilled water rinses. 4.0 ANALYTICAL CHEMISTRY PROCEDURES AND RESULTS This section discusses the analytical chemistry procedures and resulting data.
