Additional soil samples <br /> were taken in accordance with the referenced Work Plan on September 10, 1991. <br /> Tanks 6 and 16 are recommended to be backf�Iled, compacted,and closed. Tank 5 <br /> will need additional excavation. The;soil sample results from the drilling work <br /> and as reported by Curtis and Tompkins indicate that there has been no vertical <br /> migration of the chemicals from the Tank 5 site. <br /> Additionally, there appears'to be no horizontal.migration to the north or south <br /> of the Tank 5 excavation:' There is no data to the west (EI Dorado St.) or to the <br /> east (the foundation of the existing building is exposed by the tank excavation) to <br /> determine horizontal migration. The assumption is that-there has been no <br /> migration based on the borings placed north and south of the tank site. <br /> f <br /> Please call if you have any questions or require further information. <br /> 1 <br /> a <br /> Sincerely, <br /> t <br /> i MILLER ENGINEERING'S <br /> Dennis Miller <br /> Engineer „ <br /> Y . <br /> . 3 <br />
