1 <br />' Somerset Mining Company <br />1993 AHR <br />t Page 2 <br />pH - A Cole Parmer pocket-size tester. Range: -1.0 to 15.0 pH. <br />' Resolution: 0.1 pH. Accuracy: +/- 0.1 pH. Temperature <br />compensation: automatic 0 to 50 °C. Calibration: 1, 2 or 3 point. <br />' Conductivity - Two Cole Parmer pocket-size testers with different <br />range capabilities. Accuracy: +/- 2B FS. Temperature compensation: <br />automatic 0 to 50 °C. Operating temperature: 0 to 50 °C. Range: <br />0 to 1990 and 0 to 19,900 umhos/cm. <br />' Depth to Water - A Water Level Indicator (M-Scope) is used to <br />measure depth to water. The cable is marked in 5-foot increments. <br />' A tape measure is used to determine accurate distances between <br />marked increments. <br />' Temperature - A standard mercury thermometer which measures <br />temperature in degrees Celsius. <br />The pH meter and the conductivity meter are calibrated prior to all <br />' sampling events. The pH meter is calibrated using the 2 point <br />method. The expected pH is bracketed by the pH of the calibration <br />solution. In most cases the pH meter will be calibrated at 7 and <br />' 10 which will bracket all of the current monitoring results. If an <br />expected pH is less than 7, the pH meter will be calibrated at 4 <br />and 7. <br />' Water samples from H-10 and B-6 are taken with a bailer that has a <br />restricted inlet. The bailer is weighted so it sinks to the bottom <br />of the well when it is empty. The water flows into the bailer <br /> slowly so a sample of the water from the bottom of the well is <br />' obtained. It is not possible to purge wells H-10 and B-6 because <br /> they are connected to the flooded mine working. Wa ter samples from <br />' the SC-1, <br />have been SC-2, SC-3 are obtained with a bailer <br />bailed to remove the equivalent of one after the wells <br />volume of water <br /> from the wells. <br />' Flow in the ephemeral and intermittent streams and Hubbard Creek is <br />estimated by calculating the velocity of flow through a measured <br />cross-sectional area of the stream channel. Flow in the North Fork <br />' of the Gunnison is obtained from the nearby USGS gauging station. <br />Water samples were analyzed by ACZ Laboratories, Inc. of Steamboat <br />t Springs, Colorado. <br />Surface Water Information <br />Results: <br />' The data collected from the surface water monitoring stations and <br />laboratory results are presented in Appendix 3.
