SAMPLING METHODS To ensure sampling consistency, Jim Hendricks of Oakridge Energy, Inc. collected all water samples at the Cazbon Junction Mine during the 1999 water year. All water samples were tested at the Acculabs Inc. laboratory in Durango, Colorado. Grab samples for the wells were taken by lowering the sample bottle into the wells with a rope attached to a piece of PVC pipe. When the sample bottle reached the water it was filled and retrieved. Appropriately sized and labeled bottles for ground water sampling were obtained from the laboratory prior to sampling. A depth meter that was lowered down the well on a spool measured depth to water. The meter indicated it had reached the water by a beep (generated by an electric current), and the measurement was taken. Meters were also used to determine pH, temperature, and electrical conductivity from the grab samples. Grab samples were collected from the springs as close to the visible source of water as possible in an azea of undisturbed flow. Appropriately sized and labeled bottles for surface water sampling were obtained from the laboratory prior to sampling. Flow measurements were derived for the springs by visually estimating the amount of water flowing from the springs in gallons per minute. • RESULTS -SPRINGS FOR WATER YEAR 1999 Three springs were sampled during the 1999 water year. Spring 1 (iJpper Cazbon Junction Canyon) above the mine did not flow during water year 1999. The springs sampled were Spring 3 (REA SPG #3), Spring 4 (CJ-LO-SPG #4), and the Haulroad Spring. Springs 3 and 4 originate below the mine and permit azea. Spring 3 (REA SPG #3) is approximately 1,000 feet south of the permit azea in REA Canyon. Spring 4 (CJ- LO-SPG #4) is approximately 200 feet west of the permit area in Cazbon Junction Canyon. The Haulroad Spring originates from the face of the east side of the hauUoad cut below the south pit. S~~**~maries of the data collected for the 1999 water year for the springs are found in Tables 1, 2, and 3. Spring sampling occurred during the fast quarter of the 1999 water year (October- December 1998). No spring sampling occurred during the second quarter (January-Mazch 1999). Both Spring 3 and Spring 4 continued to flow during the thud quarter of this water year, and were sampled during April 1999. Flow rates at springs 3 and 4 appear to respond to seasonal recharge. Both springs show increased flow during the third quarter of the water year, presumably in response to winter recharge, and reveal decreased flow or no flow during the summer and fall. During years with low snow pack, such as 1997-1998 and 1998-1999, flow rates are reduced when compared with other years. No significant changes in spring flow were observed during -3-
