■ 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 /> 3.3. Sampling Procedures <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 held 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 soil/bum 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 /> 3. 0.1 N nitric acid rinse <br /> 4. Deionized/distilled water rinse 2x <br /> CIWMB 16 <br />
