acceptable range of the original value obtained. The duplicate value for total <br /> dissolved solids was 918 of the origin al value (350 mg/1-original vs. 320 mg/1- <br /> duplicate). The duplicate value for po tassium was 998 of the original value (1.6 <br /> mg/1-original vs. 1.5 mg/1-duplicate). Finally, the duplicate value for iron was <br /> 1118 of the original value (0.09 mg/1- original vs. 0.10 mq/1-duplicate). <br /> The October duplicate for TR-B s howed 12 out of 15 parameters to be within the <br /> acceptable range of the original value obtained. The duplicate sample value for <br /> total dissolved solids was 858 of the original value (260 mg/1-original vs. 220 <br /> mg/1-duplicate). The duplicate sample value for orthophosphate was 598 of the <br /> original value (0.017 mg/1-original vs . 0.010 mg/1-duplicate). Finally, the <br /> duplicate sample value for sulfate was 1108 of the original value (100 mg/1-original <br /> vs. 110 mg/1-duplicate). <br />VIZ. SPRING AND SEEP SURVEY <br />A survey was conducted May 7-8, 1997, to locate springs and seeps which may <br />exist at the base of the ridge along Trout Creek from the northern Moffat boundary <br />to the base of West Ridge. A total of 15 springs and 19 seeps were located as a <br />result of the survey (see enclosed map). Appendix C contains a listing of the <br />springs and seeps shown on the enclosed map and indicates those observed during 1997 <br />and in previous years. All of the springs located during the 1997 survey were <br />located in 1996 and 1995, except for one additional spring. The additional spring <br />observed during the 1997 survey was located directly above the Moffat sediment pond <br />in an undisturbed area immediately below some of the most recently reclaimed Moffat <br />Area. <br />Twelve of the 15 springs exhibited sufficient discharge for flow to be <br />estimated or calculated and field parameters measured. Nine of the 19 seeps also <br />exhibited sufficient discharge for flow to be estimated and field parameters <br />measured. Flow estimates and field parameters for these springs and seeps are <br />provided in Appendix C. Several of the springs and seeps were sampled as single <br />units due to their close proximity to each other and their apparent common origin. <br />Springs SPR 1, SPR 3, SPR 9, SPR 5, SPR 6, SPR 7, SPR 12, SPR 13, SPR 19, SPR 16 and <br />SPR 17 had sufficient flow, singularly or in combination with other springs, to <br />require additional laboratory water quality sampling in accordance with the mine's <br />. permit. As such, single combined water samples were collected for springs SPR 3 and <br />SPR 9; SPR 5, SPR6 and SPR 7; SPR 12, SPR 13, and SPR 19; and SPR 16 and SPR 17. <br />96 <br />
