2. 0 MONITORING METHODS <br /> 2 . 1 Surface Water <br /> Surface water data was collected monthly at each of the 12 <br /> designated stations PRS-1, PRS-2, PRS-3, WPD-1, MDNE-1, MDGE-1, <br /> Pond 005, CCS-1, CCS-2, LCS-1, WCS-1 and CHC-1. Expanded water <br /> chemistry samples were collected quarterly at surface water stations <br /> WPD-1, Pond 005, MDNE-1, MDGE-1, CCS-1, CCS-2, LCS-1, WCS-1 and <br /> CHC-1. Quarterly samples were taken in February, May, August and <br /> November. The November sampling was also considered the annual sample <br /> with additional water chemistry analyses being performed at all <br /> stations. <br /> During each monthly sampling, in-situ water quality measurements <br /> of temperature, conductivity, dissolved oxygen, and pH were made using <br /> a Hydro Lab Model 4000 field sampling kit. An expanded list of water <br /> quality parameters was collected during the quarterly sampling which <br /> were sent to Core Laboratories, Inc. , of Denver for laboratory <br /> analysis. <br /> Quality control of water analyses was performed by two methods. <br /> Prior to any field sampling, the Hydro Lab Sampling Kit was calibrated <br /> to known standards produced in the laboratory. A record of each <br /> calibration was kept as to the date, person performing the calibra- <br /> tion, and adjustments made. Core Laboratories, Inc. also maintains <br /> internal quality control of sample handling and instrumentation <br /> calibration. <br /> Water quantity or flow measurements were conducted by a number <br /> of methods. At the beginning of the program, a straight, flat, stable <br /> reach of each stream station was selected as a sampling location. <br /> Near the downstream end of the reach, a cross-section was surveyed <br /> perpendicular to the stream flow and permanently marked with stakes <br /> -9- <br />
