zoos <br />is to be used in analyses of embanlQnent stability of the Refuse Disposal land fill. <br />Measurements are reported in Table A-24. Data (annual minimum, maximum, mean) for <br />1994 through 2000 are presented in Table A-25. <br />UST Monitoring and Remediation Wells <br />As approved by CDPHE, the remediation system and monitoring wells were removed in 1999. The <br />NPDES discharge permit for the system has also been terminated. <br />MW-1: MW-1 a well, was drilled to characterize and monitor remediation work of apparent <br />leakage from underground storage tanks (removed) located near the Industrial Building <br />at the New Elk Mine. This monitor station was located beyond the anticipated limits of <br />any contamination plume. <br />MW-2: MW-2, a well, was drilled to characterize and monitor remediation work of apparent <br />leakage from underground storage tanks (removed) located near the Industrial Building <br />at the New Elk Mine. This monitor station was located beyond the anticipated limits of <br />any contamination plume that might extend in a direction toward the Purgatoire River. <br />MW-3: MW-3, a well, was drilled to characterize and monitor remediation work of apparent <br />leakage from underground storage tanks (removed) located neaz the Industrial Building <br />at the New Elk Mine. This monitor station was located above the anticipated limits of <br />any contamination plume. <br />MW-4: MW-4, a well, was drilled to characterize and monitor remediation work of apparent <br />leakage from underground storage tanks (removed) located near the Industrial Building <br />at the New Elk Mine. This monitor station was located above the anticipated limits of <br />any contamination plume. <br />MW-5: MW-5, a well, was drilled to characterize and monitor remediation work of appazent <br />leakage from underground storage tanks (removed) located near the Industrial Building <br />at the New Elk Mine. This monitor station was located within the area of anticipated <br />highest levels of potential contamination. <br />MW-6: MW-6, a well, was drilled to characterize and monitor remediation work of apparent <br />leakage from underground storage tanks (removed) located near the Industrial Building <br />at the New Elk Mine. This monitor station was located within the azea of anticipated <br />moderate levels of potential contamination, and to monitor the influence of the <br />groundwater surface to pumping from recovery well RW-1. <br />MW-7: MW-7, a well, was drilled to chazacterize and monitor remediation work of apparent <br />leakage from underground storage tanks (removed) located near the Industrial Building <br />at the New Elk Mine. This monitor station was located within the azea of anticipated <br />lower levels of potential contamination. <br />MW-8: MW-8, a well, was drilled to chazacterize and monitor remediation work of apparent <br />leakage from underground storage tanks (removed) located near the Industriat Building <br />626-AnnualHydrolic Monitoring(Apr.9.02).dac 11 <br />April l7, 2002 <br />
