This submittal represents continuation of <br /> routine monthly reporting of water quality monitoring results, and includes data from the new <br /> groundwater monitoring wells. There was not enough water in monitor well 16 to collect a <br /> sample. <br /> Due to malfunctioning mine pool depth probes, this submittal does not include daily mine <br /> water level measurements for the month of June 2014. Data from both mine pool depth probes <br /> installed by Cotter show that neither probe is responding to fluctuations in the depth of the <br /> mine pool as shown by physical measurements on April 4, May 2, July 18 and September 18, <br /> 2014. Alexco Corporation installed a depth probe as part of its mine water treatment system, <br /> but technical difficulties have frustrated data retrieval. Cotter is in the process of ordering and <br /> installing a new depth sensor. The elevation of the mine pool on September 18 was 6585.0 feet <br /> above sea level. <br /> If you have any questions, please contact me at 719-275-7413 (ext. 202). <br /> Sincerely, <br /> M1 <br /> hn S.
