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 />field QAPP.DOC 9-22 <br />May 2000 <br />
