SURFACE WATER MONITORING <br />There are eight (8) surtace monitoring points within Bear Coal's permitted area. <br />Pond 004, Outfall 001, Upstream North Fork (U/S NFG), Downstream North Fork (D/S <br />NFG), Spring G26A, G-26B, G-26C and CR- 12. Location of Pond 004 and NFG's can <br />be found on map "Figure 11"located in Appendix A and spring locations on map <br />"Geology/Hydrology" also located in Appendix A. <br />The French Drains were not monitored during the year because they were <br />removed during the 1997 reclamation project. <br />The results of groundwater data collected during 2004 and pertinent water <br />quality parameters are found below. <br />North Fork of the Gunnison River <br />The North Fork of the Gunnison River (USGS Station 09132500) is to be monitored <br />during June and December for field parameters and laboratory analysis for conductivity, <br />total dissolved solids, total suspended solids, iron and Manganese. Actual stream flows <br />are obtained from the web (http://nwis-colo.cr.usgs.gov) or by contacting the <br />Department of Water Resources, Colorado River Talk at 303-831-7135. Results of the <br />monitoring follows: <br />Field Analysis 8/24/2004 Field Analysis 12/13/04 <br /> U/S NFG D/S NFG U(S NFG D/S NFG <br />pH - su 8.9 8.8 pH - su 8.6 8.5 <br />Temp °C 19.4 20.0 Temp °C 0.2 0.3 <br />Cond umhos/cm 190 210 Cond umhos/cm 170 200 <br />Flow -cfs 243 Flow -cfs 77 on 12/28/04 <br />Laboratory Analysis 8/26/2004 Laboratory Analysis 12/15/2004 <br />Cond umhos/cm Cond umhos/cm 186 218 <br />TSS - mg/I TSS - mg/I 0 0 <br />TDS - mg/I 140 150 TDS - mg/I 130 150 <br />Iron - mg/I 0.43 0.43 Iron - mg/I 0.19 0.20 <br />Manganese <br />mg/I 0.023 0.024 Manganese <br />mg/I 0.006 0.011 <br />Iron and Manganese are both analyzed for total recoverable.
