Reusable sampling equipment must be decontaminated prior to sampling, in between sampling <br /> locations, and before leaving the site. Sampling equipment that should be field decontaminated includes, but is <br /> not limited to, excavator buckets, hand augers, shovels, split-spoon samplers, compositing bowls, <br /> spoons/trowels,water level indicators,oil-water interface probes, pumps,and other non-disposable equipment. <br /> Sampling supplies such as jars,gloves, bailers, etc., must also be clean to avoid cross-contamination. Disposable <br /> equipment such as disposable bailers and nitrile gloves should be properly disposed in accordance with federal, <br /> state, and local regulations and may require decontamination if necessary to meet regulatory requirements. <br /> On a site-specific basis, decontamination of larger equipment (i.e., drill rig, augers, trucks) may be required. <br /> Mini excavator buckets are considered sampling equipment and not larger equipment. The mini excavator <br /> bucket, based on a Volvo Model EC35C, has a standard bucket size of 0.1 cubic yard and is 15-inches wide. <br /> The decontamination procedure for larger equipment must be established prior to the initiation of field <br /> activities by the project manager or client. Large equipment decontamination is briefly described in this SOP; <br /> more extensive decontamination procedures, if required, should be outlined in a project-specific Materials <br /> Management Plan or Work Plan. <br /> Field personnel should also be aware of potential contamination on their boots or clothing. Special care should <br /> be noted to ensure contamination is not transferred to the inside or left on the outside of vehicles.The outside <br /> of field equipment and the carrying cases should be wiped down and decontaminated as necessary prior to <br /> leaving a site. <br /> Decontamination Procedures for Field Equipment <br /> December 23, 2022 <br /> Page I of 4 <br />
