The leadville Mill Environmental Sampling Procedures <br />Water Sample Collection <br />Page 2 -17 <br />The bailer and other equipment placed in the well should be clean (i.e., <br />decontaminated) or new and handled with new surgical gloves to preclude potential <br />contamination. Objects entering the well should not be allowed to contact the <br />ground or other potentially contaminated surface. If an item is contaminated, it <br />should not be placed in the well or utilized for sampling. <br />Sampling pumps can be used for both the sampling and evacuation of the well. Wells <br />may be purged with a submersible pump using a uniform rate of discharge. It is <br />anticipated that purged water will be discharged directly to the ground surface. <br />2.8 SAMPLE CONTAINER PREPARATION <br />This procedure is intended for bottles shipped directly from a supplier without being <br />previously cleaned. <br />Cleaning Bottles That Will Be Used for Water Samples to Be Analyzed for Inorganics <br />• Wash the bottles and caps in a mixture of hot tap water and laboratory <br />detergent (Alconox). Then rinse them in hot tap water. <br />• Next, rinse these bottles and caps once with each of the following materials in <br />succession: <br />0 0.1 Normal nitric acid (reagent grade or better), then tap water, <br />0 0.1 Normal hydrochloric acid (reagent grade or better), then tap <br />water, and <br />o Distilled /deionized (DS /DI) water. <br />Drain and allow bottles to dry in a dust -free atmosphere. <br />• Store bottles in a clean area with their caps tightly shut. <br />2.9 FIELD SAMPLING OF LIQUIDS IN PITS, PONDS & COLLECTION <br />RESERVOIRS <br />A pond sampler shall be used to collect liquid samples from pits, ponds, streams, and <br />collection reservoirs such as mixing boxes or sumps. A pond sampler consists of an <br />adjustable clamp attached to the end of a two or three piece telescoping aluminum <br />pole that serves as the handle. The clamp is used to secure a sampling beaker or <br />sample container. Samples can be obtained at distances as far away as 15 feet from <br />April 2013 <br />
