• Both of these holes, as well as the hole sampled for <br />Pit 1, demonstrate excellent correlation for increasing sodium <br />concentrations towards the southern nose of the McCallum Anticline. <br />Hole LM1B-4 (near the nose of the anticline) has the highest <br />weighted mean value of 50.87 with the values rapidly decreasing to <br />the north on the east flank in Hole 1 (20.70) and on the west <br />flank in Hole LM2C-5 (11.97). Information on S.A.R. values from <br />Kerr's pit also seem to verify this trend of decreasing S.A.R. values <br />to the north. <br />Lime <br />The values for lime are generally low ranging from 1.5$ <br />to 15.28 with the weighted mean for hole LM1B-4 being 5.620 and <br />for hole LM2C-5 being 6.488. Both of these values are well within <br />the "good" category as defined by Wyoming Guidelines. No toxicity <br />problems will result with respect to lime in potential topsoil suit- <br />ability or groundwater quality. <br />• <br />Boron <br />The analyses for boron were run only on the samples in <br />hole LM1B-4 and for the zones immediately above and below the <br />Sudduth Coal in hole LM2C-5. As was the case for lime, the values <br />for boron are well below the maximum acceptable for the "good" <br />category (5 ppm). The range of values in hole LM1B-4 is from less <br />than 0.05 to 4.5, with the weighted mean being less than 1.5. No <br />possible toxicity problems will result with respect to boron. <br />Selenium <br />The samples analyzed for selenium were the same as those <br />for boron. All selenium concentrations are very low and range from <br />0.04 to 0.74 with a weighted mean of 0.27. These values are at the <br />low end of the "good" category. Selenium will not cause any <br />. potential toxicity problems. <br />_y~_ <br />
