1 <br />' those given in Section 5.2 for the surface water and ground water <br />samples. <br />Process samples will be analyzed by the same methods for total <br />cyanide as described in Section 6.3.2 below. WAD cyanide will be <br />analyzed using ASTM Method "C", or APHA/AWWA "Standard Methods", <br />' Method I, page 4-38. Methods for the analysis of copper, zinc, <br />iron, calcium and sodium are the same as those given in Section <br />' S.2. <br /> <br /> <br />1 <br /> <br /> <br /> <br />LJ <br /> <br /> <br />1 <br /> <br />I~ <br />6.3.2 Total Cyanide Analysis Only: If there is sufficient sample for <br />cyanide analysis only, total cyanide will be determined based on <br />using either of the approved USEPA methods: Method 335.2, the <br />manual method; or Method 335.3, the autoanalyzer method. However, <br />the potential matrix effects suggest that the manual method, Method <br />335.2, is preferred if sufficient volume of sample is obtained. <br />In practice, the analytical laboratory will use the more rigorous <br />procedures with respect to analysis of standards, calibration <br />procedures and other QA/QC issues consistent with USEPA total <br />cyanide Method 9010 (manual) and Method 9012 (autoanalyzer), given <br />in Appendix G. <br />Specifically, all calibration samples will be processed through the <br />entire analytical procedure to attempt to compensate for sample <br />matrix effects and the potential presence of reduced sulphur <br />species in the porous cup lysimeter samples. This is effectively <br />a method of standard additions to the sample matrix for calibration <br />through the entire analytical procedure. <br />6.4 Quality Control <br />6.4.1 Full Analysis: Where there is sufficient sample for the analysis <br />of all the parameters listed in Table 2, then the quality control <br />-41- <br /> <br />
