The tanks and piping were shipped under <br /> non-hazardous waste manifests to Cal-Coast Manufacturing in <br /> +� Turlock, 'California. Cal-Coast Manufacturing is a facility <br /> approved by SJCPHS to accept tanks for reuse or recycling. <br /> Shipping manifests for the tanks and rinsates are presented in <br /> +r Appendix B. <br /> Sampling and Analysis <br /> Bulk samples of the native soil materials were obtained from <br /> i.• beneath each tank and from the side walls of the excavation through <br /> the use of the backhoe bucket. Figure 1 illustrates the sample <br /> locations. The soil samples collected for analytical testing were <br /> • obtained from the backhoe bucket through the use of a 2-inch I.D. <br /> barrel sampler advanced into the undisturbed soil contained in the <br /> backhoe bucket. Pre-cleaned brass liners (tube) were placed in the <br /> +.. sampler to retain the soil. Samples of the stockpiled soil were <br /> obtained by creating a small excavation (minimum 1-foot lateral) <br /> in the soil pile and then advancing a pre-cleaned brass tube into <br /> .. the soil. <br /> The sampling equipment used for obtaining the samples was <br /> +. thoroughly cleaned before sampling and between samples. The <br /> cleaning process included a phosphate-free detergent bath and <br /> double rinse to prevent the introduction of off-site contamination <br /> 4. and to prevent cross-contamination between samples. The soil <br /> samples were immediately sealed in the liners using aluminum foil <br />
