71 <br />0 APPENDIX I: ANALYTICAL METHODS <br />Methods comparable to those described below can be found <br />in all water analysis manuals (13, 14). The difference is <br />that the methods from manuals are authorized while the proce- <br />dures described below are sometimes changed from the author- <br />ized methods to be specifically useful to mining operations. <br />COLLECTION OF WATER SAMPLES <br />The way water is collected for analysis is perhaps more <br />critical than the analysis itself. It cannot be done using <br />any old bottle and taking any old water sample. What is <br />done during collection necessarily biases the analytical <br />results. This _ portion of the analytical _ program _hasto be <br />carefully planned. The following outlines what should be <br />• considered. <br />Collection Kit <br />The following items are necessary: <br />1. Polyethylene collection bottles 5.00 ml or lk size. <br />2. 250 ml polyethylene beaker <br />3. Laboratory wipers such as Kimwipes <br />4. Polyethylene bottle (125 ml) of reagent grade HN03 <br />diluted 1:1. <br />5. Towel <br />6. Field notebook <br />7. Thermometer for measuring water temperature. <br />8. Conductivity meter <br />9. Polyethylene bottle (500 ml) of distilled or deionized <br />•
