M 10 September 2012 AGE Project No. 11 - 1847 Page 9 of 9 labeled for storage. Drums containing purge waterwill be stored on-site pending appropriate removal and disposal . 3 .5 . 3. Sample Withdrawal Water samples will be collected from the monitoring well using a disposable polyethylene bailer or dedicated Teflon tubing used in conjunction with a Waterra inertial pump . Bailers are disposed of after one use, requiring no decontaminating and Teflon tubing used with the inertia pump is either dedicated to each well or changed at each sampling event, thereby minimizing cross contamination due to sampling devices . Samples will be drawn and collected in such a manner that agitation and exposure of the groundwater to the atmosphere are minimal . 3 . 5 .4 . Sample Handling ii Groundwater samples will be collected into laboratory supplied containers. Groundwater samples to be analyzed for constituents listed in Section 2. 3 . Samples will be collected into laboratory-supplied 40-ml VOA vials without sample preservative . Following collection , samples will be placed on ice and kept in a cooler until delivered to the laboratory for analysis . Chain of custody protocols will be used to document sample custody transfer from the field to the analytical laboratory. A chain of custody form will accompany the samples. 3 . 6 . EQUIPMENT DECONTAMINATIONMASTE MANAGEMENT All sampling tools used for sample collection , except for disposable bailers, will be thoroughly rinsed with clean water after being washed with a solution of Alconox. All down- hole drilling equipment will be pressure washed prior to starting each boring . Cuttings generated during drilling and rinseate generated during drilling and groundwater sampling activities will be containerized in properly labeled DOT-approved 55-gallon drums , and stored on-site in an area lacking public access . Disposal alternatives will be evaluated based on results of soil and water analysis. Advanced CeuEnvironmental, Inc.
