<br />2.0 MONITORING MRTIIODS <br />2.1 SURTACII FACILI'I'I1;S <br />During each monitoring event, in-situ water quality measurements ul tengicraturc. <br />conductivity, and pI-I were made. An cxpandeel list of water qu~dily ana4yscs w;+s <br />conducted during the vmual sampling period which were sent to a commercial <br />laboratory. Prior to any field samplings, the licld melees were caliliralcd to known <br />standards. <br />Water quality or IIow measurements were t:o~uluclal by a number of methods. At (hc <br />begimiing of the program, a straight llat, stable reach of each stramt station was selected <br />as a sampling location. Near the down sUcam end of the rcacb, across-section was <br />surveyed perpendicular to the stream lluw and permanently marked wish stakes and <br />flagging. Flow was measured with aTeledyne-Gurley Model G25 Pygmy type current <br />meter (ar similar type meter) using the USES six-tenl6s-depth method. <br />2.2 GROUNll WA`I'L'li Si'1'1~ S <br />Depth to water below top of the well casing was nroasurcd to the nearest tenth-lin+l using <br />an electric line water level detector. Water quality was svuplcd in the licld directly from <br />_ the wells with a hand bailer. The wells were cleared by bai4in~, at least three cr+lunurs of <br />• water (or bai]iug the well dry and allowing recharge) prier In collecting (he sample. <br />Equipment and procedures useJ for water chemisUy :utalysis were consistent ~cilh Ihosc <br />described above for surface water. <br />• <br />I: <br />
