5.0 DECONTAMINATION PROCEDURES <br /> All equipment coming in contact with potentially contaminated media will be decontaminated <br /> before and after each use to ensure the quality of samples collected. Disposable equipment will not <br /> be decontaminated,but will be packaged for proper disposal. All downhole drilling equipment will <br /> be steam cleaned between boreholes and prior to first use. The soil sampler will be cleaned after <br /> each sample is collected by washing in an Alconox and water solution, followed by two rinses in <br /> potable water. Decontamination of drilling equipment will be performed at the LNC site and the <br /> decontamination water will be collected in 55-gallon drums for future transport to an appropriate <br /> disposal facility. <br /> Environmental/LNC/Workplan/Appendix 2.wpd 14 <br />
