Newmont CRIPPLE CREEK & VICTOR <br /> PO Box191 <br /> 100 N.3rd Street <br /> CRIPPLE CREEK&VICTOR <br /> Victor CO 80860 <br /> If the field values indicate stable conditions, collect, preserve, and handle the <br /> samples according to the procedures outlined in this document. An example of a <br /> well purging calculation is included in Appendix E. <br /> 8.6. Stream Sampling <br /> Sampling results will vary with depth, stream flow, and distance from shore. When <br /> rinsing the field cup or bottles, discard the rinsate downstream from the sampling <br /> point. A grab sample should be collected at mid-depth from the middle of the <br /> stream, in an actively flowing section of the stream. In shallow streams, care <br /> should be taken not to disturb the bottom and put sediments into suspension, as <br /> these will affect the analytical results. If a stream has no visible flow, it will be <br /> recorded as dry and will not be sampled. If a stream sampling location has visible <br /> water, but not enough water to allow collection of a representative sample, it will <br /> be recorded as "too low to sample". An estimate of the flow rate of water at each <br /> • stream sampling location should be recorded in the field book, along with the <br /> general appearance of the water (turbidity, color, etc.). <br /> 9. POND SAMPLING <br /> If possible, sample solution in the pond. If the situation requires sampling flow <br /> going into the pond, note this on the field sheet. Care should be taken to avoid <br /> stirring up sediments, and the rinsate should be discarded where it will not flow <br /> back into the pond. <br /> 9.1. Reservoir Sampling <br /> Choose location, depth, and frequency of sampling according to local conditions, <br /> the purpose of the investigation, and the tests or analyses to be made. Seasonal <br /> stratification, rainfall, runoff, and wind will cause considerable variations <br /> throughout the body of water. Do not collect the sample in an area of extreme <br /> turbulence, and avoid sampling at weirs. If possible, collect the samples(s) beneath <br /> the surface in quiescent areas. <br /> Department THIS DOCUMENT IS UNCONTROLLED IN HARD COPY FORMAT Doc Id: <br /> SER.
