------------- <br /> rf=•���=J <br /> A sand envelope will then be placed around the clot to the 8 foDt <br /> depth, and then neat cement with 5's bentonite will be used to <br /> veal the well from the 8 foot depth to the surface. A water <br /> tight 12inch diameter traffic box will be placed over the well <br /> casing for traffic <br /> flocked twoion. Security of inchthermos cap atthe thewell es <br /> ill be <br /> provided by the top of <br /> casing. <br /> WELL DEVELOPMENT <br /> Upon completion of the well, it will be surged and bailed for <br /> development, using a surge block to agitate the sand pack and <br /> ground water. A centrifugal pump will be used to purge the well <br /> until relatively sediment free water is produced. <br /> STORAGE OF CUTTINGS, PURGED GROUND WATER AND RINSATES <br /> All cuttings produced from the sample borings and -.nstallation of <br /> MW4 will be contained on and -vered with 4 mill polyethylene <br /> liner and stored in the locked compound behind the store. All <br /> rinsate and purged ground water will also be contained on site in <br /> labeled 55 gallon drums. <br /> DESTRUCTION OF SAMPLE BORINGS <br /> _s All sample borings will be destroyed using a neat cement with 5k 4 <br /> bentonite mixture and the surface will be patched to match the <br /> pre-existing conditions: asphalt, concrete, etc. <br /> DISPOSAL OF EXCAVATED SOIL AND PURGED WATER-RINSATE <br /> Upon obtaining laboratory results, the contained soil and water <br /> will be disposed of in accordance to the State of California and <br /> County of San Joaquin guidelines. <br /> REPORT OF FINDINGS <br /> At the completion of this investigation a report of the findings <br /> will be submitted to Desert Petroleum for their review. Once <br /> Desert is satisfied as to the completeness of this investigation, <br /> they will issue Western Geo-Engineers a statement as to their <br /> approval for the distribution of the report. <br /> This investigation is being performed under the direct <br /> supervision of Ca. Reg. Geologist #3037 . All drilling will be <br /> performed under C57 license 513857 . <br /> HEALTH AND SAFETY <br /> Pvious e can <br /> are <br /> elevel Dnprotectionnsite, see Appendixate that sBsitHealthbetreated <br /> and Safety <br /> Plan. <br /> page3 <br />
