Nitrate <br />• Nitrate was marginally suspect in the increments from 86-95 feet <br />and above the hlghside suspect level of 20 ppm in the interval <br />95-100. <br />Sodium Absorption Ratio <br />SAR was marginally suspect in the interval 86-95 feet: 12.7 <br />compared to the standard of 12. <br />m u <br />Marginally suspect levels, 0.11 - 0.13 ppm compared to the <br />suspect range of 0.10 - 1.0 ppm are found from 10-50 feet in <br />29-9. The alkaline nature of the overburden should preclude any <br />problem with the available cadmium. <br />Molybedenum met but did not exceed the standard in the interval <br />50-70 feet of 29-9. Again the alkaline nature should preclude <br />problems with molybdenum. <br />• Nicke~l~marginally exceeded the standard, 1.08 ppm compared to 1.0 <br />ppm for the interval 40-50 feet of 29-4. All other nickel values <br />are well within tolerance. <br />Zinc <br />Zinc exceeded the standard in four non-adjoining intervals: <br />0-10 feet 37 ppm <br />15-20 feet 45 ppm <br />70-85 feet 64 ppm <br />95-100 feet 34 ppm <br />In discussions with Dan Matthews of MLRD and Stan Nielson of <br />Colorado Analytical Laboratory there view was that plant growth <br />would not be hampered by levels in excess of 30 ppm. Mr. <br />Matthews suggested that the zinc availability to plants would be <br />impaired by the alkalinity of the overburden. <br />Non-commercial, Waste Coal <br />The comparison includes the Sopris seam and the coal bench <br />beneath the Engleville Seam (Lower Engleville Bench), Exhibit 0. <br />• The total sulfur of the Sopris Seam was 0.89 k of which 0.49 8 <br />was pyritic sulfur.
