2.0 MONITORING METHODS <br />• <br />2.1 SURFACE FACILITIES <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 <br />conducted during the annual sampling period which were sent to a commercial <br />laboratory. Prior to any field samplings, the field meters were calibrated to known <br />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 station was selected <br />as a sampling location. Neaz the down stream end of the reach, across-section was <br />surveyed perpendicular to the stream flow and permanently marked with stakes and <br />flagging. Flow was measured with aTeledyne-Gurley Model 625 Pygmy type current <br />meter (or similar type meter) using the USGS six-tenths-depth method. <br />2.2 GROUND WATER SITES <br />Depth to water below top of the well casing was measured to the neazest tenth-foot using <br />an electric line water level detector. Water quality was sampled in the field directly from <br />• the wells with a hand bailer. The wells were cleared by bailing at least three columns of <br />water (or bailing the well dry and allowing recharge) prior to collecting the sample. <br />Equipment and procedures used for water chemistry analysis were consistent with those <br />described above for surface water. <br /> <br />13 <br />
