Newmont,M CRIPPLE CREEK & VICTOR <br /> PO Box 191 <br /> CRIPPLE CREEK&VICTOR 1ictorC 8086Street <br /> Victor CO 80860 <br /> Duplicate and control samples will be identified with an ID#which will not bias the <br /> laboratory by indicating the origin of the sample. At CC&V duplicate samples are <br /> identified by increasing the numerical component of the monitor well identifier by <br /> 100, and offsetting the position nomenclature by positive 5 (Increasing the letter <br /> count by 5). For example the duplicate for monitoring well VIN-2A would be VIN- <br /> 102F, the duplicate for monitoring well GVMW-22B would be GVMW-122G. It is <br /> also necessary that all pertinent field data for the duplicate sample be recorded <br /> as any sample, and that the sample ID is identified as a duplicate, and which well <br /> it is a duplicate for is identified. <br /> Blank samples will be identified with an ID# which will not bias the laboratory by <br /> indicating the origin of the sample. At CC&V rinse blank samples are identified by <br /> using the prefix RB# where the # is the sequential number for the rinse blank <br /> sampled that day and then following it by the month numerical value and the day <br /> numerical value (two digit). For example the first rinse blank sample collected on <br /> March 25 would be identified as RB1-0325, the second rinse blank sampled <br /> • collected on March 25 would be identified as RB2-0325. It is also necessary that <br /> field data be collected for the blank sample (pH, DO, EC, temp). Field data for all <br /> collected rinse blanks needs to be recorded on a field sample sheet. <br /> 8.4. Sample Collection <br /> Decontaminate all non-dedicated sampling equipment and meters, as <br /> appropriate, before and after use with deionized water (Type III reagent grade). <br /> Decontamination procedures include cleaning of equipment with a dilute <br /> phosphate free detergent solution (i.e. Alconox or Liquinox), followed by a fresh <br /> water rinse. <br /> To assure an undiluted sample is collected, field cups, filter vessels, or other <br /> reusable equipment should be triple rinsed with sample solution if sufficient <br /> quantities are available. <br /> Field readings will be measured from a separate container collected at the same <br /> time as the sample, and will not be taken from the actual sample bottle which will <br /> be analyzed. If a field sample was taken from a lined facility, it must be returned <br /> • to a lined facility. Minimum field readings will be pH, conductivity, and <br /> temperature. <br /> Department THIS DOCUMENT IS UNCONTROLLED IN HARD COPY FORMAT Doc Id: <br /> SFR Date of This Issue--/--/-- Date of Next Review:--/--/-- Page 22 of 73 <br />
