• Moving the location of dewatering trenches or pumps to locations at greater distances from <br />affected wells. <br />PRE-RECLAMATION SITE MODELING AND POST-RECLAMATION IMPACTS <br />Prior to reclamation of the site, which will include water storage facilities, it may be necessary to <br />perform further modeling based on recorded monitoring data in an attempt to better demonstrate <br />the long-term impacts to the outwash aquifer. <br />Based on the results of the present study, it is expected that some mounding on the up-gradient <br />side of the lined pit will occur. The mounding would be most acute on the northwest and west sides <br />of the liner. Due to the influx of ground water flow from the northwest, a perimeter drain may be <br />necessary to protect any up-gradient structures, as well as the stability of the pit liner itself. <br />Adverse impacts from shadowing effects are not anticipated on the down-gradient side of the lined <br />pit. This is partially because there are no structures that could be impacted by the shadowing, but <br />also due to the fact that the close proximity with the Arkansas River will help to alleviate any <br />possible shadowing. The only structure located down-gradient of the site appears to be the existing <br />rail line running parallel to the river. The rail grade should not be adversely impacted by a slight <br />decrease in the prevailing ground water table following reclamation. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />Parkdale Aggregate Mine I Conclusions and Recommendations ? <br />
