PAW-8: This station was installed and monitoring began in 1994 to monitor the effects of the Refuse Disposal Area at the New Elk Mine on Purgatoire River alluvial groundwater. The well is located on the north river bank. Data collected (annual minimum, maximum, mean) collected from 1994 to date are presented in Table B-5. PAW -9: This station was installed and monitoring began in 1994 to monitor the overall effects of the New Elk activities on alluvial groundwater. This well is located on the south bank of the river near PRS-4. Data collected (annual minimum, maximum, mean) collected from 1994 to date are presented in Table B-6. New Elk Mine Water Levels NEW -1: This sample station, the west portal shaft of the New Elk Mine, was established to monitor the recovery (flooding} and quality of water of the sealed New Elk Mine. Reclamation work has resulted in the loss of this station. NEW-2: This sample station, the east portal shaft of the New EIk Mine, was established to monitor the recovery (flooding} and quality of water of the sealed New Elk Mine. Data collected at this station are presented in Table B-9. NEW-3: A dip sample from the Apache Canyon shag, used to assess the rate of flooding and the quality of water in the New EIk mine workings following sealing (see B- 10). • NEW-4: This sample station, a well, located down-dip a sufficient distance from the portals to reach a known flooded portion of the sealed New Elk Mine (near the conveyor belt), was established to monitor the recovery (flooding) and quality of water. Data collected at this station (annual minimum, maximum, mean) for 1994 through 2001 are presented in Table B-11. Refuse Disposal Area Piezometers TH-201; Station TH-201, a piezometer, was installed on the lowest bench of the Refuse Disposal Area fill (Bench 1) to determine the level of the piezometric surface within the embankment. TH-202: Station TH-202, a piezometer, was installed in the Refuse Disposal Area (Bench 2) to determine the level of the piezometric surface within the embankment. TH-203: Station TH-203, a piezometer, was installed in the Refuse Disposal Area (Bench 3) to determine the Level of the piezometric surface within the embankment. This information is to be used in analyses of embankment stability of the Refuse Disposal land fill. Measurements (annual minimum, maximum, mean) for 1994 through 2001 are presented in Table B-12.
