Document Owner: Climax Mine Environmental Department <br />Review Cycle: As Needed <br />Document Name: Environmental Water Quality Sampling <br />Last Revised /Reviewed On: 06 -27 -2011 <br />Page 6 of 6 <br />Document Class: EMS <br />• Make comments as needed, shipper is sometimes requested <br />• The bottom copy of the COC will be retained in a separate binder in the Climax laboratory. <br />The samples will be placed in a cooler, provided by the laboratory or Climax, with the completed <br />COC. Ice must be added to the cooler to insure that the samples arrive at approximately 4 Celsius. <br />Add packaging material (e.g., bubble wrap) if needed to keep samples from shifting position in the <br />cooler. <br />Quality Assurance /Quality Control <br />Field duplicates will be used to document the precision and accuracy of the sampling. Field <br />duplicates are co- located samples collected identically and consecutively over a minimum period of <br />time. Field duplicates are sent to the laboratory and analyzed for identical chemical parameters. This <br />sample will document field precision. <br />The sampling location for the field duplicate shall be selected randomly prior to the sampling event. <br />One field duplicate shall be collected during each quarterly water sampling event. Not all sample <br />locations will be sampled during each sampling event nor will each have a field duplicate each time it <br />is sampled. <br />Documentation <br />The sampling program will be documented to provide a summary of the sample collection procedures <br />• and conditions, shipment method, the analysis requested and the custody history. Documentation <br />shall include: <br />• Field notebook <br />• Water sampling forms <br />• Sample labels <br />• Chain -of- custody forms <br />• Shipping receipts <br />All documentation shall be placed in the project file and retained. <br />IF YOU HAVE ANY QUESTIONS REGARDING <br />THESE PROCEDURES, PLEASE CONTACT THE ENVIRONMENTAL DEPARTMENT <br />Revision History <br />Rev <br />06 -27 -11 <br />Revision Summary <br />SOP Issued <br />PRINTED DOCUMENTS ARE UNCONTROLLED <br />
