3.0 MONITORING WELL CONSTRUCTION <br />3.1 ROAD DEVELOPMENT <br />At site GWMS-01 an existing road will be upgraded for the <br />surface water monitoring proposed at SWGS-04 and to accomo- <br />date necessary drilling of one set of alluvial wells. Ground <br />Water Monitoring Station GWMS-02 will require a road to be <br />built for drilling purposes only. After the wells are <br />drilled the road can be reclaimed. For purposes of monitoring, <br />Powderhorn will use the existing Cottonwood Creek Road after <br />completion of the wells and reclamation of the drill road. <br />At site GWMS-03 an existing road will have to be upgraded to <br />allow access for drilling and monitoring purposes. <br />3.2 WELL CONSTRUCTION <br />At sites GWMS-01, GWMS-02, and GWMS-03, two wells will be <br />developed at each site. The wells will be spaced a minimum of <br />five feet apart but not greater than 10 feet apart. Each well <br />will be completed and cased to bedrock. One well will contain <br />perforated casing along its entire depth, and the second well will <br />contain perforated casing in the lowermost portion of the alluvium. <br />The well perforated along the entire depth will be designated <br />"Well P. The well perforated only at the lowermost section will <br />be designated "Well A". Refer to Figures 1 and 2 for drawings <br />showing the proposed well construction. <br />-2- <br />
