• Hydrographs of 1979 Transect Wells in the Eclaran Park Drainage; and the <br />Eclanan Park Stream Channel Cross Sections (Map 51), and the lack of base <br />flow to the stream in the summer months from ground water crontribution. <br />As docwnented in Figure 44, Hydrographs of 1979 Transect Wells in the <br />Eclrnian Park Drainage, the water table under the ephgneral stream is <br />lowered substantially by underflow drainage in summer, and does not <br />provide water to the stream or root zone. It is concluded, therefore, <br />that ground water availability in the study area is not sufficient for <br />subirrigation. <br />Water Quality. The water quality of the study area is based on <br />samples taken on a weekly basis throughout the spring runoff season on <br />one well from each of the seven transects. These data are presented in <br />• Table 6, Summary of Energy Fuels Corporation Ground Water Quality Charac- <br />teristics. The predominant water type is calcium bicarbonate, inter- <br />mixed with sodium and sulfate ions. Well and surface water samples were <br />very similar in chemical characteristics and ionic content as shown by <br />cromparing the above table with Table 14, Summary of Energy Fuels Corpora- <br />tion Surface Water Quality characteristics, indicating that there is <br />little or no wntribution from bedrock aquifers to shallow ground water <br />or streams in the study area. Average chemical characteristics were a pH <br />of 7.15, electrical wnductivity of 718.9 umho/cm, calcium carbonate <br />hardness of 358.8 n5/1, and total dissolved solids of 630.9 mg/1. These <br />data indicate alkalinity and moderately high salt load, making the water <br />marginally useful only for stack or agricultural purposes. <br />Water Quantity. Stream-flow has been measured in Eckman Park by the <br />. United States Geological Survey at gaging station number 09243800 on <br />785-9(j) <br />
