• acceptable range of the original value obtained. The duplicate value for potassium was 908 of the original value (1 .9 mg/1-original vs. 1.7 mg/1-duplicate). The duplicate value for sodium was 91~ of the original value (10.0 mg/1-original vs. 9.1 mg/1-duplicate). Finally, the duplicate value for ortho-phosphate was 688 of the original value (0.024 mg/1-original vs. 0.021 mg/1-duplicate). The October duplicate for TR-B showed 12 out of 15 parameters to be within the acceptable range of the original value obtained. The duplicate sample value for iron was 107$ of the original value (0.14 mg/1-original vs. 0.15 mg/1-duplicate). The duplicate sample value for manganese was 1078 of the original value (0.060 mg/1- original vs. 0.064 mg/1-duplicate). Finally, the duplicate sample value for potassium was lOBB of the original value (1.2 mg/1-original vs. 1.3 mg/1-duplicate). VII. SPRING AND SEEP 9DAVEY A survey was conducted May 7-14, 1998, to locate springs and seeps which may exist at the base of the ridge along Trout Creek from the northern Moffat boundary to the base of West Ridge. A total of 11 springs and 15 seeps were located as a . result of the survey (see enclosed map). Appendix C contains a listing of the springs and seeps shown on the enclosed map and indicates those observed during 1998 and in previous years. All of the springs located during the 1998 survey were located in 1997. Eight of the 11 springs exhibited sufficient discharge for flow to be estimated or calculated and field parameters measured. Seven of the 15 seeps also exhibited sufficient discharge for flow to be estimated and field parameters measured. Flow estimates and Field parameters for these springs and seeps are provided in Appendix C. Several of the springs and seeps were sampled as single units due to their close proximity to each other and their apparent common origin. Springs SPR 1, SPR 3, SPR 5, SPR 6, SPR 7, SPR 16 and SPR 17, and Seep SE 23 had sufficient flow, singularly or in combination with other springs or seeps, to require additional laboratory water quality sampling in accordance with the mine's permit. As such, single combined water samples were collected for springs SPR 5, SPR6 and SPR 7; and SPR 16 and SPR 17. Results of these analyses are provided in Appendix C. 98
