precharged bottles and submitting them to ACZ Laboratories, Inc. of <br />Steamboat Springs, Colorado, for analyses. <br />' Results: <br />' There was no flow at monitoring points AG-1 "A" Gulch, BG-1 <br />"B" Gulch, CG-1 "C" Gulch, HG-1 Hoopla Gulch or BC-1 Bardine Canyon <br />during 1992. <br />The data collected from the surface water monitoring stations <br />and laboratory results is presented in Appendix 2. Graphs of major <br />I chemical parameters are also included in this appendix. Quarterly <br />inspection reports on the sediment control ponds located in the <br />permit area are included in Appendix 4. <br />There was no discharge from the Elk Creek or Hubbard Creek <br />facility areas for the reporting period of 1992. <br />After evaluating field test and water analysis reports, it is <br />evident that water quantity and quality fluctuated according to the <br />seasonal Spring runoff and precipitation. Somerset Mining Company <br />in conjunction with the Colorado Department of Health (CDH), is <br />currently reviewing the impact of discharge water from Outfall 011 <br />and until the CDH has completed review of the effluent toxicity <br />=I data, and a decision for action is made, Somerset Mining is <br />required to continue normal quarterly acute testing. <br />,~I <br />~~ Methods: <br />GROD'NDWATER MONITORING <br />Water quality and samples were collected using a hand bailer. <br />Parameters of temperature, Ph, conductivity and salinity were <br />determined in the field, and water levels were recorded from the <br />top of the well casing and reported as elevations. All other <br />parameters were determined as described in the surface methods <br />section of this report. <br />Results: <br />Results of groundwater data collected during 1992 are <br />presented in Appendix 3. Graphs of the pertinent water quality <br />parameters are also shown in this appendix. <br />
