r <. <br />Chimney Rock Mine <br />A hydrologic monitoring program was implemented at the Chimney Rock Mine <br />located 20 miles southwest of Pagosa Springs, Colorado, in October 1980. This program <br />currently consists of three surface stations located on Stollsteimer Creek which flows <br />adjacent to the mined areas. The results of monitoring activities for the period of June 1991 <br />are summarized in the following paragraphs with summary data sheets attached. <br />Surface Water Monitoring <br />Surface water monitoring was conducted at three locations on Stollsteimer Creek (S-1, <br />S-2 and S-3). Flow conditions were average for this season of the year. Fiow measured on <br />Stollsteimer Creek range from 9.35 cfs at S-2 to 7.93 cfs at S-3. Crest gauges examined at <br />the three stations indicated 1.10 feet at station S-1, 2.00 feet at S-2, and 1.10 feet at S-3. <br />Water quality samples were collected at each of the three surface stations during the <br />June sampling. The water is classified as a mixed calcium-magnesium/sulfate-bicarbonate <br />water with relatively low concentrations of metals and mineralization. Water chemistry was <br />consistent with previous samp]ings. No oil and grease was found in any of the surface water <br />samples. <br />A spring and seep survey was conducted on March 28, 1991, in the area of the mine <br />pits and surface disturbance area. A small seep was observed in the reclaimed area <br />approximately at the rock underdrain location out of the east pit. Several other seeps were <br />noted along the stream bank of the AVF area near surface station S-2. The same seep in <br />the rock underdrain area was observed again during the June sampling. <br />Groundwater Monitoring <br />During August 1991, all groundwater monitoring wells were reclaimed. Prior to <br />reclamation, water samples were obtained from wells W-9, W-10, and W-16. Sample results <br />are consistent with the previous sampling conducted in September 1990. Alluvial wells W-1 <br />and W-5 were dry. No analyses were conducted at wells A-1, W-6, W-7, W-17 and W-18. <br />
