• with Table 9, Suitability Ratings for Soils as Sources of Topsoil Material, the 5.3 level <br />received a poor rating, while all other pH levels recorded are good, with the exception of <br />5.9 which received a fair rating. These results are in line with the general information <br />provided by the SCS and should not cause any severe ]imitations. <br />Electrical Conductivity <br />A total of 10 samples were analyzed for electrical conductivity. The range of electrical <br />conductivity for both the topsoil and subsoil varied from .30 to .50 mm hos/cm. No samples <br />exceeded the level of four mm hos/cm as described in Table 9, Suitability Ratings for Soils <br />as Sources of Topsoil Material. Calcium, magnesium and sodium levels for each of the 10 <br />samples are also very low, which is expected, as electrical conductivity is a function of those <br />soluble actions. Therefore, the suitability guidelines recommended by the Wyoming DEQ <br />indicate that all topsoil and subsoil within the permit area is considered god with respect to <br />the criteria for electrical conductivity. <br />Saturation Percentage <br />The same number of samples, identified above, were analyzed for saturation percentage. <br />Values received indicate levels ranging from 37.5 to 49.9%. No levels were encountered <br />below 25 or above 80, as described in the Wyoming DEQ Guidelines (Table 9). Soils <br />encountered within the permit area are considered "good" with respect to saturation <br />• percentage. <br />Sodium Absorption Ratio <br />A total of 10 samples were analyzed for sodium absorption ratio. The values received range <br />from .16 to .63. None of the samples exceed the recommended value os six as described in <br />the aforementioned guidelines (Table 9). Accordingly, the soils in the permit area are <br />considered "good" with respect to the sodium absorption ratio. <br />Boron <br />A total of 10 samples were analyzed for boron. Boron levels as described in the Wyoming <br />DEQ Suitability Ratings for Soils as Sources of Topsoil Material (Table 9), should not <br />exceed 5 ppm. In accordance with the rating described in the above referenced table, the <br />soils within the permit area are rated as "good" with respect to boron levels. <br />Selenium <br />A total of 10 samples were analyzed for selenium within the permit area. Table 8, Soil <br />Analysis, indicates selenium levels range from less than .010 ppm to .025ppm. In accordance <br />with Table 9, Suitability Ratings for Soils as Sources of Topsoil Material, selenium levels <br />within the permit area are well below those described in the Wyoming DEQ Guidelines <br />• 2.04-32 <br />
