i S <br />Ms. Jamie Gaboriau <br />April !7, 1002 ' <br />Page 4 of 4 <br />obtained from similar dewatering operations and alluvial characteristics. Therefore,'it `, . <br />is unlikely that dewatering operations. at the pit alone have caused a complete dew <br />down of the alluvial a uifer. <br />• A well located aggroximately 1400 feet from the southern-most Brancucci wells was - <br />observed:pumging (WCR 4 and 27). The amount and extent of pumping is not known; <br />however, the discharge observed at the pump appeared to close to a fixll pipe indicatirig <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 lasf several years, particularly this past winter; has <br />probably had a significant impact upon the amount of recharge realized by the aliu~ial,' _ <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 fmd this information helpful.
