<br />Ms. Janet Binns <br />January 29, 1997 <br />Page 2 <br />chronic metal standards and ammonia concentrations. Iron <br />concentrations were elevated in the 1996 sample from Pond 1, but <br />that is probably attributable to the high total suspended solids <br />(711 mg/1) or concentration of elements due to evaporation and the <br />time of year that the water sample was taken. The pond water <br />quality meets all CDMG Material Damage standards e:tcept the aquatic <br />life standard for mercury. <br />Water levels increased substantially in Well 7 during 1996 from <br />previous years (Table 3). The depth to water was 72.62 feet, an <br />increase of more than 19 feet over 1995. Total depth of the well <br />is 110 feet. Water levels have risen 30 feet in the last ten <br />years (Figure 3). This general increase in water levels indicate <br />the recovery of the potentiometric surface due to cessation of <br />mining at Canadian Strip and more recently with the reclamation of <br />the Kerr Mine to the north. The snowpack during the winter of <br />`95/`96 was average, but rainfall during the summer was elevated, <br />resulting in precipitation in the North Platte drainage 129 percent <br />of normal. <br />Well 7 is monitoring a slightly alkaline sodium bicarbonate (Figure <br />1) water of moderate salinity (TDS of 1430 mg/1), and moderate <br />hardness (314 mg/1) (Table 3). The water meets all Colorado <br />groundwater quality standards except the secondary drinking water <br />standards for iron, manganese and sulfate. Figure 2 is a trilinear <br />diagram comparing general water quality in the well over the last <br />15 years. <br />Should you have questions or need additional information concerning <br />hydrologic monitoring, please do not hesitate to let me know. <br />Sincerely, <br />~~ <br />~ ~~ <br />Jerry H. Koblitz <br />Permit Coordinator <br />Attachments <br />cc: Lawrence J. Corte - Senior Environmental Attorney - KN Energy <br />
