CLAW-1 Alluvial well located at the mouth of Ciruela Canyon. Established to <br />monitor potential effects of Golden Eagle mining and surface activities in <br />the canyon. <br />ACAW-1 Alluvial well located at the mouth of Apache Canyon. Established to <br />monitor potential effects of mining in the canyon. <br />Contained in the following sections is a description of the methods and results of the <br />first quarter of monitoring activities conducted at the New Elk and Golden Eagle mine <br />sites. <br />2.0 Surface Water Monitoring <br />Monthly surface water samplings were conducted at each of the five designated <br />stations PRS-1, PRS-2, PRS-3, MDNE-1 and MDGE-1 on 6 to 8 March, 28 and 29 March, <br />and 24 April. Quarterly surface water samplings were conducted at each of the six <br />designated stations CCS-1, CCS-2, SCF-1, ACF-1, MDNE-1 and MDGE-1 on 6 to 8 March. <br />2.1 Methods <br />During each monthly sampling, in-situ water quality measurements of temperature, <br />conductivity, pH, and dissolved oxygen were made using a Hydro Lab Model 4000 field <br />sampling kit. An expanded list of water quality parameters was collected during the <br />quarterly sampling which was sent to Core Laboratories, Inc., of Denver for laboratory <br />analysis. Filtration of certain water quality parameters was accomplished in the field <br />with a Geotech 2.4 liter barrel filter. <br />Water quantity or flow measurements were conducted by a number of methods. At <br />the beginning of the program, a straight, flat, stable reach of each stream station was <br />selected as a sampling location. Near the downstream end of the reach, across-section <br />was 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 using the USGS six-tenths-depth method. At the mine discharge stations, discharge <br />was measured by the pump ratings or by a direct volumetric measurement with a <br />calibrated container. In Apache and Santistevan Canyons, calibrated flume stations were <br />
