Kennedy/Jenks/Chilton <br /> Attachment A to Kennedy/Jenks/Chilton's <br /> letter to Mr. Ron yalinoti <br /> dated 13 October 1989 <br /> hazardous materials. <br /> After the monitoring well is installed and time has been allowed for the <br /> cement to cure (at least 24 hours) , the well will be developed by bailing <br /> and/or pumping to remove fine sediment from the well and to stabilize <br /> soils around the screen. Well development will continue until water is <br /> visibly clear or a minimum of 9 well casing volumes of water have been <br /> removed. Well development water will be placed in D.O.T. drums approved <br /> for the storage and transport of hazardous materials. <br /> Immediately after development is completed, the well will be purged of an <br /> additional three well casing volumes and then immediately sampled. <br /> Groundwater samples will be collected using a clean Teflon bailer. <br /> Samples will be stored in properly preserved sample bottles, sealed, <br /> labeled, and placed in an ice chest for transport to <br /> Kennedy/Jenks/Chilton's Laboratory Division in San Francisco or another <br /> State certified laboratory for analysis. A chain-of-custody form will be <br /> completed for all groundwater samples collected. Water samples will be <br /> analyzed for TPH and BXTE using GC/FID techniques. Quality assurance/ <br /> quality control (QA/QC) protocol will include a field blank, a travel <br /> blank, and a field duplicate. <br /> The four monitoring wells drilled as part of the preliminary site <br /> investigation (MW-1, MW-2, MW-3, MW-4) will also be sampled. The wells <br /> will be purged by bailing or pumping each well until the equivalent of <br /> three casing volumes of water have been removed. The groundwater sample <br /> will then be collected using a clean Teflon bailer. Samples will be <br /> transferred to properly preserved sample containers, sealed, labeled, and <br /> placed in a chilled ice chest with completed chain-of-custody forms for <br /> shipment to Kennedy/Jenks/Chilton's Laboratory Division in San Francisco <br /> or another State certified laboratory. The water will be analyzed for <br /> TPH and BXTE. <br /> Drums containing cuttings generated during the drilling and water <br /> generated from the well development and purging will be labeled as to <br /> contents, date of generation, and well location and number. Analytical <br /> information from water samples collected will be provided to Cal -Farm <br /> Supply for its use in determining proper waste disposal methods. The <br /> drummed soil cuttings will be aerated along with the soil material <br /> excavated during tank removal . <br /> WPNMLI:STOCKTON.WP2 A - 6 <br />
