field parameters. Flow measurements were not obtained for the springs during the <br />sampling. <br />Well Monitorine: Water Year 2004 <br />The groundwater wells that were monitored in water yeaz 2004 were 17-B (upgradient of <br />the mine) and 95-1 (located downgradient of the mine). Wells 17-B and 95-1 were <br />sampled twice in the first quarter of this water year (October 7, 2003 and December 18, <br />2003), once during the second quarter (Mazch 23, 2004), once during this water yeaz's <br />third quarter (June 22, 2004), and once during the fourth quarter (August 30, 2004). A <br />full-suite analysis of pazameters was conducted, as were field pazameters for the wells <br />during sampling. <br />SAMPLING METHODS <br />To ensure sampling consistency, CDS, Inc. personnel collected all water samples at the <br />Carbon Junction Mine during the 2004 water year. All water samples were analyzed at <br />Green Analytical Laboratories, Inc. laboratory in Durango. <br />Grab samples for the wells were taken by lowering the sample bottle into the wells with a <br />rope attached to a piece of PVC pipe. When the sample bottle reached the water it was <br />filled and retrieved. Appropriately sized and Labeled bottles for ground water sampling <br />were obtained from the laboratory prior to sampling. <br />A depth meter that was lowered down the well on a spool measured depth to water. The <br />meter indicated it had reached the water by a beep (generated by an electric current), and <br />the measurement was taken. Meters were also used to determine pH, temperature, and <br />electrical conductivity from the grab samples. <br />Grab samples were collected from the springs as close to the visible source of water as <br />possible in an area of undisturbed flow. Appropriately sized and labeled bottles for <br />surface water sampling were obtained from the laboratory prior to sampling. Meters were <br />also used to determine pH, temperature, and electrical conductivity from the spring flow in <br />the field. <br />Sediment pond 002 discharged once this water year (September 2004). Michael Savage <br />of Savage and Savage, Inc. was present during the dischazge and obtained a compliance <br />sample for the CDPS permit. The sample was delivered to Green Analytical Labs in <br />Durango, Colorado for analysis. The sample results for this sample aze appended with the <br />dischazge monitoring reports. <br />Chain of custody for the samples was maintained and these records are appended with the <br />laboratory summaries. <br /> <br />Carbon Junctbn Mine Page S <br />Mnual Hydrologic RePorc for Water Year?A04 <br />
