As previously discussed, placing a borehole NE of the warehouse to investigate down <br /> gradient of HP-9,which contained 1.04 ppm motor oil. <br /> 2. Define the vertical extent of motor oil in the forma storage area. This would include �d i ►N <br /> taking a set of Samples in a vertical profile to a dep*where contamination was no longer p <br /> observed in the field. lf` <br /> 3. Sample preparation for testing should include filtration and non-filtratiou to determine the <br /> amount of motor oil in solution verses the amount adsorbed to the soil particles. Thus we c� �} <br /> could use this information as a guide to interpret the previous water data. <br /> I wilt keep you informcd as the project progrenes. 10 <br /> +�t <br /> Ray <br /> :Tow z �r" 0 �v <br /> Ss <br /> !(1A (rJE <br /> r <br />
