<br />C. E. Johnston <br />AHR Review <br />Page 2 <br />conductivity in Ward Creek has increased. Therefore, Minrec will <br />not sample Ward Creek for TDS or sample the alluvial wells or the <br />wells completed in the E-Seam. <br />The Division's basis to request Minrec to perform additional <br />monitoring is based upon; 1) the flawed opinion that the <br />conductivity of lower Ward Creek is increasing; and 2) the fact <br />that monitoring performed during September 18, 1993, showed the <br />conductivity of Spring 1 was near its historic high and the <br />conductivity of Spring 3 was at its historic high. Enclosed is a <br />table that presents conductivity and flow data for Springs 1 ~ 3. <br />I do not believe the relatively slight increase in the conductivity <br />of the springs warrants the additional monitoring requested by the <br />Division. <br />Minrec will continue to sample the seeps noted in the sediment <br />pond. The bottom elevation of the pond is approximately 20 feet <br />above the D-Seam. According to Appendix G, Red Canyon #2 Portal <br />Cut Geotechnical Investigation, the portals to the D-Seam were to <br />be faced up by an open cut in the bottom of the sediment pond. <br />The source of the spring water in the bottom of the sediment pond <br />could be; 1) seepage from irrigation water in the main drainage <br />channel or; 2) ground water. The elevation of the water measured <br />in piezometers P-1 and P-2 is about 6315 which is just seven feet <br />below the bottom of the sediment pond. A 2.88 water surface <br />gradient would connect the seeps and the piezometers. <br />Please call if you have any questions. <br />Sincerely, <br />.vJ~OU~ <br />Jim Stover, P.E. <br />Chief Engineer <br />Enclosures <br />
