' 2. F 1 ace 6 auger holes g s5 at appro<imate locations as shown on <br /> Plate VII; auger holes A, D, C , D, cf E are programmed to :5 bgl . <br /> ' <br /> It is planned to advance auger hole F to appro r 1 matel y 50 bgl , <br /> (a fes,•, feet into the estimated 198eD high water level , ) to <br /> determine if contamination reached that depth. � <br /> ' 3. Soil samples will be taken at approximately 1 , an❑ at 5 <br /> intervals from 5 ' bgl to deepest penetration.
