Newmont,., CRIPPLE CREEK & VICTOR <br /> PO Box 191 <br /> CRIPPLE CREEK & VICTOR 100N.3'dStreet <br /> Victor CO 80860 <br /> 8.1. General Guidelines <br /> A sampling event (day) should be scheduled to collect background samples first, <br /> and samples such as process solutions last, to avoid cross contamination of wells <br /> or streams. <br /> Samples will be collected in new sample bottles of material consistent with the <br /> parameters to be analyzed. DO NOT touch the inside of sample vessel or cap or <br /> allow these surfaces to contact any material other than the sample media. Sample <br /> containers that are known, or suspected, to be contaminated will be discarded or <br /> clearly marked with an "X" or other designation to prevent their use. Holding times, <br /> minimum required sample bottles/volume, and necessary preservative types are <br /> contained within Attachment I. <br /> Table 8.1.1 below contains the required sample bottle, bottle volume, and <br /> preservative for the various analysis suites CC&V uses for our water monitoring <br /> • program. <br /> Table 8.1.1 -Sample Bottle Requirements by Analysis Suite <br /> Surface Water Analysis Suite <br /> 1-500 mL HDPE unpreserved sample(grab sample) Black Label <br /> 1-250 mL HDPE unfiltered sample(grab sample) preserved with 1.25 mL H2SO4(Sulfuric Acid,yellow label) <br /> 1-250 mL HDPE unfiltered sample(grab sample) preserved with 1.25 mL HNO3(Nitric Acid,red label) <br /> 1-250 mL HDPE filtered sample(grab sample)preserved with 1.25 mL HNO3(Nitric Acid, red label) <br /> 1-250 mL Amber HDPE unfiltered sample(grab sample) preserved with 1.25 mL NaOH (Pre-preserved bottle or <br /> Sodium Hydroxide,green label) <br /> 1-Hexavalent Chromium Kit(pre-preserved)adjust pH as needed with NaOH (Sodium Hydroxide,Green Label)to <br /> achieve pH between 9.3-9.7.
