i 2 <br />' sampling dates are to be: May, August, November, and February. The sampling; <br />will coincide with the major hydrologica] event.; of the year. <br />Sampling sites are identified in Figure 1 and ?. March samp]ing differs <br />' slightly with subsequent sampling because certain points in the mine were <br />sealed off and became unavailable. The October samplint; inc]uded the source <br />' of the water (in the 0 C Mine) (Station ~,) which flows out of the adit at the <br />t Nu-Mine (Station 5). The Nu-Mine adit is collapsed (Photo ] in Appendix i). <br />Table 1 provides the data obtained in the three samplings completed thus <br />far. Colorado Analytical Laboratory, Brighton, carried out all of the <br />elemental sampling. The Western State College Water Quality Laboratory did <br />the other work (Table 2). <br />' SOILS <br />' Soil samples were taken to illustrate site diversity, and to reflect <br />substrate available for reclamation. The soils are considered from the stand- <br />' point of: depth, texture, type, and capability to support ['rowth. Some <br />information was gained on site; some information was obtained at the Western <br />' State College laboratory; much information was provided by Hunter and Spears <br />' (1975). Locations for collection included the existing mine benches near <br />the ad?t, at the bottom of the dry retention pond, and representative sites <br />' near the mine adit and over the previous workings, to the extent of the previous <br />workings. A distance of 1600 feet, in a northwesterly direction, was con- <br />' sidered to be the limit of the previous workings. <br />' Examination of typical representative soils, bench soil and pond sediment <br />ind]ude: pH, conductivity, calcium, mngpiesiiun, sodium, SAR, boron, copper, <br />molybdenum, plus parameters cited nt,ove. With the exception of the capahil.ity <br />to support growth, all tests will be conducted Ly the Colorado Analytical <br /> <br />
