The HNU readings were used along with visual observations to <br /> screen samples for laboratory analysis. A summary of soil field screening results is presented <br /> in Table 3. <br /> 3.9 SAMPLE CARE AND IiANDLING <br /> All soil and groundwater samples were handled in accordance with USTEC policy for the care <br /> u and handling of samples as defined in the site specific work plan. Soil samples were prepared <br /> by covering the ends of each sample retainer with aluminum foil and capping with plastic <br /> endcaps. The caps were then sealed with duct tape, labeled, and placed in a "ziplock" style <br /> plastic bag. The samples were then placed on ice and maintained at about h° Celsius to <br /> minimize potential volatilization of organic compounds until delivery to Sequoia Analytical <br /> Laboratories. No preservatives were used except for ice. <br /> S <br /> Groundwater sample jays and vials were wrapped with 'bubble wrap" to prevent breakage and <br /> placed in "ziplock" style plastic bags. The groundwater samples were then placed on ice to <br /> minimize potential volatilization of organic compounds until delivery to Sequoia Analytical <br /> Laboratories. No preservatives were used except ice and laboratory prepared vials containing <br /> .�i hydrochloric acid. <br /> Chain-of-custody documentation was maintained by USTEC personnel and accompanied the <br /> transfer of groundwater samples from the field to Sequoia Analytical Laboratories, Redwood <br /> City, California. The c' in-af-custody documentation is included in Appendix E. <br /> 3.10 EQUIPMENT DECONTAMINATION PROCEDURES <br /> The drilling rig and associated tools were decontaminated prior to entering the site and were <br /> steam cleaned between borings. All sampling equipment used was decontaminated between <br /> samples to prevent possible cross-contamination of the samples. Specific decontamination <br /> M- procedures for all sampling equipmerkt are presented below: <br /> a o A tap water pre-wash to remove soils stuck to the equipment. <br /> o— – t1 scrub-witha long-handled bnish in an AlconaxO detergent solution. <br /> �. <br /> 9 <br />
