GROUNDWATER SAMPLING PROCEDURES <br /> Groundwater sample collection will be performed in accordance with AGE's standard <br /> monitoring and sampling procedures, which have been included as Appendix B. <br /> 3.7. BORING ABANDONMENT <br /> All soil borings not completed as groundwater monitoring wells will be permanently sealed <br /> to prevent vertical migration of potential contaminants. Soil borings shall be abandoned <br /> by backfilling with cement grout from the total depth to surface grade. Borings advanced <br /> below the groundwater table will be abandoned with grout utilizing tremie procedures. <br /> The top three to six inches of the boring abandonments will be completed flush to surface <br /> grade with concrete. The SJCEHD will be notified for grout inspection at least 48 hours <br /> prior to conducting grouting procedures <br /> 3.8. EQUIPMENT DECONTAMINATIONIWASTE MANAGEMENT <br /> All sampling tools used for sample collection, except for disposable bailers, will be <br /> thoroughly rinsed with clean water after being washed with a solution of Alconox. All <br /> down-hole drilling equipment will be pressure washed prior to starting each boring. <br /> Cuttings generated during drilling and rinseate generated during drilling and groundwater <br /> sampling activities will be containerized in properly labeled DOT-approved 55-gallon <br /> drums and stored on-site in an area lacking public access. Disposal alternatives will be <br /> evaluated based on results of soil and water analysis <br />
