III. MONITORING WELLS <br />• The table below summarizes the well designation, the <br /> top of casing el evation, the location and the <br /> aquifer monitore d during 1992. <br /> WELL <br /> DESIGNATION ELEVATION AQUIFER LOCATION <br /> FPW 4780' Ennis Draw Mine <br /> DH96 4764' Ennis Draw Downstream <br /> from Mine <br /> DH122 4814' Ennis Draw Upstream <br /> from Mine <br /> SMW-2 4803' Reclaimed Mine <br /> Spoil <br /> AMW-1 4804' Undisturbed Mine, <br /> Overburden downstream/ <br /> ash <br /> ANW-2 4811' Reclaimed Mine, <br /> Spoil downstream/ <br /> ash <br />• <br /> Included in the appendix of this report are the <br /> drill logs from each of the above quarterly <br /> monitored wells. <br />When the logs were located, a problem was discovered <br />with AMW-2. As the Division is aware, the above <br />ground casing was damaged by cattle. The casing was <br />repaired; however, a dirt plug had entered into the <br />casing. An air-track rock drill was used to remove <br />the plug and remove by air any loose material in the <br />casing. After the well was cleared, the total depth <br />was 38.3 feet which is consistent with the previous <br />level. When the log for this well was located, the <br />total depth was reported at 44 feet with <br />perforations from 39 to 44 feet. If the design <br />criteria of the well is correct, the well is plugged <br />off above the perforations. If the design criteria <br />is incorrect, AMW-2 is completed in the wrong <br />zone. In either case, corrective action must be <br />taken. <br />• <br />Page 5 <br />
