<br />~~ <br />xe~isea 1/zs/ao <br />Section 785.19(c) Continued <br />It is concluded, therefore, that the floodplain of Foidel Creek in the <br />adjacent azea does not meet the subirrigation qualifications under water <br />availability criteria for alluvial valley floors. <br />Water Quality. The water quality of the study azea is based on samples <br />taken on a weekly basis throughout the spring runoff season on one well <br />from each of the seven transects. These data are presented in Table 6, <br />Summary of Energy Fuels Corporation Ground Water Quality Characteristics. <br />The predominant water type is calcium bicarbonate, intP**~~Xed with <br />sodium and sulfate ions. Well and surface water samples were very <br />similar in chemical characteristics and ionic content as shown by compar- <br />ing the above table with Table 14, Summary of Energy Fuels Corporation <br />Surface Water Quality ~azacteristics, indicating that there is little <br />or no contribution from bedrock aquifers to shallow ground water or <br />stre~ns in the study area or adjacent area along Foidel Creek. Average <br />chemical characteristics were a pH of 7.15, electrical conductivity of <br />718.9 uniio/cm, calcium carbonate hardness of 358.8 mg/1, sodium absorp- <br />tion ratio (SAR) of 2.09 mg/1, and total dissolved solids of 630.9 mg/1. <br />These data indicate alkalinity and moderately high salt load, making the <br />water imrginally useful for stock or agricultural purposes. <br />785-9(bb) <br />
