Interval: Hole 29-9; 86-95 feet (SAR) <br />• This interval !s marginally suspect for sodium absorption ratio. <br />It should not be placed near the surface and overburden mixing <br />should minimize any problems. <br />Interval: Hole 29-9: 10-50 feet (CADMIUM) <br />This interval is marginally suspect for cadmium. The low ph of <br />the overburden should render it unavailable for plant Lngestion. <br />Interval: Hole 29-9; 50-70 feet (MOLYBDENUM) <br />Molybdenum meets but does not exceed the standard. The interval, <br />as stated above, is marginally acceptable for sand content. <br />Burial would eliminate both the sand and molybdenum concerns. <br />Interval: Hole 29-9: 40-50 feet (NICKEL) <br />Nickel marginally exceeds the standard in this Interval. The <br />remainder of the overburden contains nickel levels well below the <br />standard, therefore overburden mixing should alleviate any <br />problem. <br />• Interval: Hole 29-9. 0-10, 15-20, 70-85 & 95-100 feet (ZINC) <br />Of all the constituents, Zinc exceeds the standard by the <br />greatest margin. Of possible concern is the level of zinc in the <br />0-10 foot increment. Since lower concentrations of zinc are <br />favorable to plant growth and the ph !s 8.5 it is unlikely that <br />the zinc will be available to plants. <br />The 70-85 foot increment is especially high, 64 ppm. However, it <br />is the same sand Interval that should not be placed in the near <br />surface spoil <br /> <br />-11- <br />
