Plastic end caps for acetate tubing ■ Mailing labels and markers <br />Chain of custody forms and custody seals ■ Cooler and ice or blue ice <br />■ Packing and duct tape <br />Decontamination equipment (2 Y2 -gallon sprayer, non -phosphate detergent, disposable <br />brush, paper towels, cotton towels, polyethylene sheeting) <br />Burn -ash and soil samples will be collected using direct push equipment. At each sample <br />location direct -push equipment will be used to drive the sampling tool through the cover and <br />waste into native soil beneath the fill. <br />Subsurface waste and soil samples will be collected by visually identifying debris through the <br />clear acetate liner of the sampling tool and cutting out a six-inch section and capping the ends <br />with plastic cap plugs. Upon completion of sampling at a location the hole will be screened <br />using a GMI 422 Gas Surveyor and a measurement taken for CH4, CO2, H2S, CO and 02. <br />The hole will then be filled with native soil and bentonite. <br />After each sample is collected it will be placed in a laboratory -supplied container, labeled, <br />logged on the chain -of -custody document, screened for radioactivity, sealed, and stored in an <br />ice chest that is cooled to 4 degrees Fahrenheit. The coolers will be shipped to ExcelChem via <br />overnight Federal Express shipment. <br />3.4. Sample Locations <br />Although sampling locations are proposed in Figure 6, exact soil sampling locations will be <br />determined in the field based on accessibility, the presence of unforeseen impedances or other <br />factors. Final soil sample locations will be recorded in the field logbook and staked in the field <br />when sampling is completed. A survey crew will locate each sampling location on the final site <br />map. The map will be provided in a final site investigation and sampling and analysis report. <br />3.5. Decontamination Procedures <br />All equipment that comes into contact with potentially contaminated soiVbum ash will be <br />decontaminated in a predesignated area. Disposable equipment intended for one-time use will <br />not be decontaminated, but will be packaged for appropriate disposal. Decontamination will <br />occur prior to and after each use of a piece of equipment. All sampling devices used, including <br />trowels and augers, will be decontaminated by CIWMB staff. <br />The following decontamination procedures for primary contaminant, inorganic (metals): <br />1. Non -phosphate detergent and tap -water (bottled water) wash, using a brush if necessary <br />2. Tap -water rinse <br />1 0.1 N nitric acid rinse <br />4. Deionized/distilled water rinse 2x <br />CIWMB 16 <br />
