• quantity of water available and the slow recharge rate of the well. The well <br />is located near the northeast edge of A-Pit, in a highly disturbed and <br />subsequently reclaimed overburden area. Completion of the final <br />reclamation of the adjacent A-Pit area is likely having a positive influence <br />on the ability of this well to recharge. <br />Copies of the summary analytical laboratory test results are available in the <br />pages following this text. Each ground water monitoring well was sampled <br />in accordance with the "permit procedure". The "B" designation following <br />the well identification indicates that the laboratory sample was obtained <br />after initial field sampling, well purging and a subsequent (second) field <br />sampling. (Again, the lack of available water in well AMW-2 limited the <br />ability to properly purge the well. Consequently, some of these samples <br />received an "A" designation.) The 2002 ground water monitoring test <br />results continue to appear consistent with results from previous water <br />quality analyses in that there were no confirmed statistical exceedences. <br />The ground water flow, to the extent documented in the area of the <br />Keenesburg Mine property, continues to trend down-gradient to the <br />• northeast. Recharge of the aquifer in the "spoil area" continues to be <br />CEC continues to believe that no adverse affect on the overall hydrologic <br />balance of the Keenesburg Mine site should result from a continuation of <br />the ash disposal operation, from the limited addition of mine waste rock to <br />the ash disposal, or from the continuing reclamation operations. Ground <br />water levels in the former coal extraction areas are expected to recover to <br />their approximate pre-mining levels following the conclusion of all CEC <br />operations (see McWhorter report, Appendix I-1 to Permit C-81-028). <br />Treatment of either the ground or surface waters at the Keenesburg Mine <br />site should not be necessary. <br />limited to a single source, the localized infiltration of precipitation to the <br />subsurface. There is no evidence of any significant ground water recharge <br />to the site from the nearby Ennis Draw fluvial ground water system. Ground <br />water elevations in the sampled Ennis Draw wells close to the Keenesburg <br />Mine site remain significantly higher than in either the spoil monitoring <br />well (SMW-2) or the ash monitoring wells (AMW-1 or AMW-2). <br />• In the course of applying for, and obtaining approval to dispose of mine <br />waste rock in the ash disposal pit (B-Pit) at the Keenesburg Mine site, CEC <br />AHR-2002 -49- <br />
