• Well Monitorine <br />Wells 10-B, 17-B, and 94-1 were monitored from the fourth quarter of 1995 through <br />the third quarter of 1996. Well 11-B was not monitored during the 1996 water year. <br />A full-suite analysis of parameters was conducted along with a field analysis of pH, <br />temperature, depth to water, and electrical conductivity. <br />SAMPLING METHODS <br />To ensure sampling consistency, Jim Hendricks of Oakridge Energy, Inc. has collectgd <br />all water samples at the Carbon Junction Mine. All water samples have been tested at <br />the CDS Laboratory in Durango, Colorado. <br />Grab samples for the wells were taken by lowering the sample bottle into the wells with <br />a rope attached to a piece of PVC pipe. When the sample bottle reached the water it <br />was filled and retrieved. Appropriately sized and labeled bottles for ground water <br />sampling were obtained from the CDS Laboratory prior to sampling. <br />Depth to water was measured by a depth meter that was lowered down the well on a <br />spool. The meter indicated it had reached the water by a beep (generated by an electric <br />current), and the measurement was taken. Meters were also used to determine pH, <br />• temperature, and 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 azea of undisturbed flow. Appropriately sized and labeled bottles for <br />surface water sampling were obtained from the CDS Laboratory prior to sampling. <br />Flow measurements were derived for the springs by visually estimating the amount of <br />water flowing from the springs in gallons per minute. <br />RESULTS -SPRINGS FOR 1996 WATER YEAR <br />Two springs were sampled during the 1996 water year. The springs sampled were <br />REA SPG !!3 and CJ-LO-SPG ~4. Both springs originate below the mine and permit <br />area. REA SPG li3 is approximately 1,000 feet south of the permit area in REA <br />Canyon. CJ-LO-SPG N4 is approximately 200 feet west of the permit area in Carbon <br />Junction Canyon. Summaries of the data collected for the 1996 water year for the <br />springs are found in Table 1 and 2. <br />The spring flow sampled for the 1996 water year showed that both springs monitored <br />had minimal flows in the first three quarters of the water year. Lower flow in the 1996 <br />water yeaz may be attributed to low snow pack in the vicinity of Carbon Junction <br />Canyon and the recharge azea of the springs. No flow was recorded for either spring <br />. during the third quarter of 1996. This is not uncommon in the historic sampling <br />record. pH is consistent for both springs at a slightly basic level. Temperature and <br />2 <br />
