• Giles and Brogden (1978) reported the results of water quality analyses of samples collected <br />in streams, springs, and wells of the Yampa River Basin in 1974 and 1975. Approximately 27 <br />samples were collected and analyzed for bacteria, trace elements, common ions, temperature <br />and pH. Temperature and specific conductivity results in the vicinity of Taylor Creek are <br />listed in Table 2. Fifteen wells were sampled in the vicinity of the Colowyo Mine. The <br />average specific conductivity measured in the wells was 1390 mmhos and the range was <br />almost as large as that for the surface water samples, 720 to 2700 mmhos. <br />After three years of data collection, the main conclusion reached by Giles and Brogden was a <br />confirmation of the general alkalinity of the water and the recognition of the variability of <br />quality in both surface and groundwater. <br />Permit Area <br />LRCWE (1979) reported measurements for temperature and specific conductance of streams, <br />springs or seeps, and wells in the vicinity of the mine. Many of the sites visited during the <br />investigation were those inventoried by others during previous investigations in 1974 and <br />1975. <br /> <br />I~~ <br />2.04.7-13 <br />
