• Board, certain other parameters were subsequently added. A list <br />of these parameters is found in Table 3. <br />The analyses of each of the Table 3 parameters on the forty- <br />four samples are listed in Table 4. A statistical analysis of the <br />Wyoming basic parameter list is found in Table 5. This analysis <br />includes a weight-averaged mean, minimum, maximum and range for each <br />parameter. The weight-averaged mean is determined by multiplying <br />the thickness of each lithology times the parameter value, adding <br />each resultant value together, and dividing by the total thickness <br />of the forty-four samples. These results are discussed below: <br />pH <br />Values for pH range from a low of 7.3 to a high of 8.8 <br />and have a weighted mean value of 8.25. All of these values are <br />alkaline and are below the "unsuitable" designation according to <br />Wyoming Guideline No. 3. The mean value of 8.25 places the pH within <br />• the "good" category and, hence, no alkaline problems should be <br />encountered with respect to pH. <br />Electrical Conductivity, E.C. <br />The values for E.C. range from 2.Smmhos/cm to 18.4 mm <br />hos/cm with the weighted mean value being 4.77. This value falls <br />within the "fair" category according to Wyoming Guidelines. The <br />only zone which shows an E.C. in excess of 16mmhos/cm ("unsuitable" <br />by Wyoming Guidelines) is the top 10 feet of the hole which repre- <br />sents the subtopsoil horizon (very high in clay-sized particles). <br />No toxicity problems will result from any of the overburden beneath <br />the topsoil layer with respect to electrical conductivity. <br />Saturation Percent, SAT <br /> All of the samples tested exhibit saturation percentages <br />• well within the range of 25-80& set forth in the Wyoming Guidelines. <br />-16- <br />
