Ms. Jamie Gaboriau • • <br />April 17, 2002 <br />Page 4 of 4 <br />obtained from similaz dewatering operations and alluvial characteristics. Therefore, it <br />is unlikely that dewatering operations at the pit alone have caused a complete draw <br />down of the alluvial aquifer. <br />• A well located approximately 1400 feet from the southern-most Brancucci wells was <br />observed pumping (WCR 4 and 27). The amount and extent of pumping is not known; <br />however, the discharge observed at the pump appeazed to close to a full pipe indicating <br />good conditions at the well. <br />• Other areas (ponds) that were observed east of the pit and subject wells also reflect a <br />lower water level. This may be representative of the overall decline in the area water <br />table due to the extended dry spell. <br />• The extended dry spell over the last several years, particularly this past winter, has <br />probably had a significant impact upon the amount of rechazge realized by the alluvial <br />aquifer. This in conjunction with the discharge from the Platte Valley Pit may have <br />contributed to the drop in water levels east of the pit. <br />I trust you will find this information helpful. Should you have any questions or comments, <br />please feel free to contact me. <br />Cordially, <br />Applegate Group, one. <br />~-~~.,,~ <br />William A. Warmack, P.
