October 2012 <br />2.0 MONITORING METHODS <br />2.1 Surface Facilities <br />Page 2 -1 <br />During each monitoring event, in situ water quality measurements of temperature, <br />conductivity, and pH were made. An expanded list of water quality analyses was conducted <br />during the annual sampling period from samples that were sent to a commercial laboratory. Prior <br />to any field samplings, the field meters were calibrated to known standards. <br />Water quality or flow measurements were conducted by a number of methods. At the <br />beginning of the program, a straight, flat, stable reach of each stream was selected as a sampling <br />location. Near the downstream end of the reach, a cross section was surveyed perpendicular to <br />the stream flow and permanently marked with stakes and flagging. Flow was measured with a <br />Teledyne- Gurley Model 625 Pygmy type current meter (or similar type meter) using the USGS <br />six - tenths -depth method. Lesser flows were monitored using a Parshall Flume with a two -inch <br />throat. <br />2.2 Ground Water Sites <br />Depth to water below top of the well casing was measured to the nearest tenth -foot using <br />an electric line water level detector. Water quality was sampled in the field directly from the <br />wells with a hand bailer. The wells were cleared by bailing at least three columns of water (or <br />bailing the well dry and allowing recharge) prior to collecting the sample. Equipment and <br />procedures used for water chemistry analysis were consistent with those described above for <br />surface water. <br />
