CA ARNG Field Quality Assurance Project plan <br /> 9.3.2.2 Decontamination of groundwater and soil sampling tools will generally be performed in the <br /> sinks on the CPT rigs. Large water reservoirs and a water heater will provide hot running water for <br /> decontamination.The sinks will be filled with the appropriate washes as outlined in the specifications. <br /> 9.3.2.3 Push rod decontamination will be performed with an automatic steam cleaning collar.The collar <br /> consists of rubber wipers and three jet nozzles where high pressure steam is injected as the rods are <br /> pulled into the truck.Both the inside and outside of the groundwater sampling rods are steam cleaned <br /> using the steam cleaner/high pressure washer from the support rig once the rods are pulled from the <br /> ground. Steam cleaning the inside of the groundwater sampling rod is generally performed, because the <br /> bailer may have spilled inside the rod while being retrieved. <br /> `e <br /> field QAPP.DOC 9-22 <br /> May 2000 <br />
