• auger by six-inch depth intervals (0 to 6, 6 to 12, etc.). At least 500 <br />grams were collected for each sample and they were bagged in zip-locking <br />plastic bags, labelled, and sent to the lab for analysis. <br />Samples were analyzed in accordance with standard procedures for <br />the following parameters: pH; electrical conductivity; soluble Ca, Mg, Na, <br />sodium absorption ratio, saturation percentage, organic matter, and <br />particle size analysis. <br />Map 9, Soils, presents the soils for the PPA and RI19. Several <br />different soil types occurred: Rombo channery silty clay loam, Midnight <br />channery clay loam, Lowiers channery clay loam, disturbed areas (mine <br />waste), Vamer stony loam, Dargol stony loam, Fuera stony loam, and Noden <br />loam. Descriptions and additional information concerning these soils is <br />presented in Fbchibit 14, Soils Information. <br />The approximate location of the sample sites in the refuse <br />• ~ disposal area are shown on Map 9, Soils. Table 15, Soils Analysis Results <br />for RDA, are the analysis results for the samples taken by six-inch depth <br />increments. Generally, the results indicate that the material is <br />chemically suitable as a plant growth medium. Table 16, Suitability <br />Criteria of Topsoil, is generally accepted suitability criteria for topsoil <br />material. <br />In the proposed PPA, no topsoil would be salvaged because none <br />exists. in the RDA however, site soils will be salvaged prior to <br />construction. Nearly all of the soil that would be disturbed by the refuse <br />disposal site is mapped as the Rambo series with areas of the Midnight, <br />Louviers, and Vamer soils also affected. All of these soil types have <br />approximately the same depth (less than or equal to 16 inches) and nearly <br />the same percentage of coarse fragments throughout the profile (25 to 50 <br />percent). While this material would normally not be considered physically <br />suitable for salvage (see Table 16, Suitability Criteria of Topsoil) <br />because of its skeletal nature, it is being salvaged here because it is the <br />• best material available. <br />2.04-37 <br />
