SURFACE WATER MONITORING <br />There are eight (8) surface 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-266, 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 1999 and pertinent water <br />quality parameters are found below. <br />North Fork of the Gunnison River <br />The North Fork of the Gunnison River is monitored during June (July this year) and <br />December for field parameters and laboratory analysis for conductivity, total dissolved <br />solids, total suspended solids, iron and Manganese. Actual stream flows are obtained <br />from the web (http://nwis-colo.cr.usgs.gov) or by contacting the Department of Water <br />Resources, Colorado River Talk at 303-831-7135. Results of the monitoring follows: <br />Field Analysis 7/12/99 Field Analysis 12/6/99 <br /> U/S NFG D/S NFG U/S NFG D/S NFG <br />pH - su 8.4 8.4 pH - su 8.6 8.5 <br />Temp °C 18.0 18.5 Temp °C 0.6 0.6 <br />Cond <br />umhos/cm 80 110 Cond <br />umhos/cm 160 160 <br />Flow -cfs 230 230 Flow -cfs 203 203 <br />Laboratory Analysis 7/12/99 Laboratory Analysis 12/6/99 <br />Cond <br />umhos/cm 111 132 Cond <br />umhos/cm 204 231 <br />TSS - mg/I 0 0 TSS - mg/I 6 0 <br />TDS - mg/I 60 80 TDS - mg/i 120 130 <br />Iron - mg/I 0.11 0.16 Iron - mg/I 0.06 0.07 <br />Manganese <br />mg/I 0.008 0.012 Manganese <br />mg/I 0.017 0.014 <br />• Iron and Manganese are both analyzed for total recoverable. <br />-3- <br />
