All sampling equipment will be decontaminated prior to <br /> fx sampling following these same procedures. <br /> Soil sample.; will be collected as monitoring wall drilling <br /> progresses. All downhole drilling equipment will be <br /> d. decontaminated prior to use and between use for each well <br /> according to the procedures described in Section 6.0. <br /> F� All well construction material, including well casing, <br /> #.Q screen, and well caps, will be decontaminated prior to <br /> installation by steam cleaning according to the procedures <br /> ►' described in Section 6.0. <br /> To prevent the transfer of surface contamination to a well, <br /> a Portland cement and bentonite surface seal will be <br /> f installed in conformance with regulatory requirements. The <br /> )' casing will be fitted with a water tight locking cap. No <br /> solvent or glue will be used in well construction. The <br /> I; wellhead will be contained below, grade in a water-tight <br /> i# traffic rated box or otherwise protected from damage. <br /> E-. In order to assure that groundwater samples are obtained <br /> from formation material and not from the filter pack, wells <br /> will be purged in accordance with the appended <br /> Wall Development Protocol. <br /> i <br /> Samples will be placed in laboratory__prepared containers:. <br /> appropriate for the analyses specified as indicated on Table <br /> r <br /> �v <br />
