zool <br />~ PAW-8: This station was installed and monitoring began in 1994 to monitor the effects of the <br />Refuse Disposal Area at the New Elk Mine on Purgatoire River alluvial groundwater. <br />The well is located on the north river bank. Data collected during this year are presented <br />in Table A-10. Data (annual minimum, maximum, mean) collected from 1994 to date are <br />_ presented in Table A-11. <br />PAW-9: This station was installed and monitoring began in 1994 to monitor the overall effects of <br />the New Elk activities on alluvial groundwater. This well is located on the south bank of <br />the river near PRS-4. Data collected during this year are presented in Table A-12. Data <br />(annual minimum, maximum, mean) collected from 1994 to date are presented in Table <br />A-13. <br />New Elk Mine Water Levels <br />NEW-1: This sample station, the west portal shafr of the New Elk Mine, was established to <br />monitor the recovery (flooding) and quality of water of the sealed New Elk Mine. <br />Reclamation work has resulted in the loss of this station. <br />NEW-2: This sample station, the east portal shaft of the New Elk Mine, was established to <br />monitor the recovery (flooding) and quality of water of the sealed New Elk Mine. Data <br />collected at this station are presented in Tables A-14 and A-15. <br />NEW-3 A dip sample from the Apache Canyon shaft, used to assess the rate of flooding and the <br />quality of water in the New Elk mine workings following sealing (see Tables A-16 and <br />A-17). <br />NEW-4: This sample station, a well, located down-dip a sufficient distance from the portals to <br />reach a known flooded portion of the sealed New Elk Mine (near the conveyor belt), was <br />established to monitor the recovery (flooding) and quality of water. Data collected at this <br />station are presented inTable A-18. Data (annual minimum, maximum, mean) for 1994 <br />through 2000 are presented in Table A-19. <br />Refuse Disposal Area Piezometers <br />TH-201: Station TH-201, a piezometer, was installed on the lowest bench of the Refuse Disposal <br />Area fill (Bench 1) to determine the level of the piezometric surface within the <br />embankment. This information is to be used in analyses of embankment stability of the <br />Refuse Disposal land fill. Measurements are reported in Table- A-20. Data (annual <br />minimum, maximum, mean) for 1994 through 2000 are presented in Table A-21. <br />TH-202: Station TH-202, a piezometer, was installed in the Refuse Disposal Area (Bench 2) to <br />detennine the ievel of the piezometric surface within the embankment. This information <br />is to be used in analyses of embankment stability of the Refuse Disposal land fill. <br />Measurements are reported in Table A-22. Data (annual minimum, maximum, mean) for <br />1994 through 2000 are presented in Table A-23. <br />TH-203: Station TH-203, a piezometer, was installed in the Refuse Disposal Area (Bench 3) to <br />determine the level ofthe piezometric surface within the embankment.
