Screen interval and drilled depth are unknown (UK). <br />Both new wells and MNGW -1 were sampled in the fourth quarter 2014. AJAX /Clear Creek <br />recommends sampling the wells on a triannual basis beginning in spring 2015 and continuing until <br />sufficient data are collected to assess baseline conditions and trends. Furthermore, water levels and <br />field parameters should be collected from the new wells and MNGW -1 on a monthly basis to <br />evaluate seasonal influences on groundwater flow direction. The results of this monitoring will <br />allow AJAX and Clear Creek to provide a more comprehensive evaluation of groundwater flow and <br />groundwater quality. <br />Please let us know if you have any additional questions. <br />Sincerely, <br />AJAX Mountain Enterprises LLC <br />A.-it W / 7 <br />Leah Wolf Martin, PG, PE <br />Project Manager <br />Clear Creek Associates, PLC <br />Mike Alter, RG <br />Principal Hydrogeologist <br />
