Page 13 <br /> 2. Wearing proper protective gear, rinse the sampling container in a decontaminated sampling <br /> bucket three times with the liquid to be sampled. <br /> 3. Slowly submerge the pond sampler into the liquid to be sampled with minimal surface <br /> disturbance. Retrieve the pond sampler from the reservoir with minimal disturbance. Pour <br /> liquid from the full pond sampler into a decontaminated sampling bucket. Continue until the <br /> required volume of liquid has been collected. <br /> 4. Measure field parameters including: pH, conductivity, temperature, and dissolved oxygen. <br /> 5. If the sample liquid contains little or no solids, stir or swirl the contents of the bucket gently. <br /> Using the sampling container, fill the sample bottles (unfiltered samples). For filtered <br /> samples, filter the sample according to procedures outlined in Appendix E, then fill the <br /> sample bottles with the filtered liquid. See Table 4 for correct bottle size and composition. <br /> Add the appropriate preservatives, if required, as indicated in Table 4. <br /> If the sample contains a large amount of suspended solids, stir or swirl the contents of the <br /> bucket gently. Allow the solids to settle to the bottom of the bucket. Dipping from the upper <br /> portion of the bucket, fill sample bottles (unfiltered samples). For filtered samples, filter the <br /> aqueous portion of the liquid according to procedures in Appendix E, then fill the sample <br /> bottles with the filtered liquid. Correct bottle size, composition, and preservatives (if <br /> required) are indicated in Table 4. <br /> 6. Label the sample bottles. Record the sampling information in the bound field logbook and <br /> complete the chain-of-custody documents. <br /> 7. Properly clean and decontaminate the sampling equipment prior to reuse or storage. <br /> Decontamination procedures are outlined in Appendix B. <br /> Sampling procedures for collecting samples from the downspouts of the Chalk Mountain <br /> Interceptor and North Interceptor canals and from the seep below Eagle Park Reservoir are as <br /> follows: <br /> 1. Wearing proper protective gear, rinse a decontaminated sample container(bucket) three times <br /> with the liquid to be sampled. <br /> • 2. Collect a grab sample from one of the downspouts or from the center of the seep sump using <br /> the sample container. <br /> PRIVILEGED AND CONFIDENTIAL <br /> — - - ----Environmental.C:(PROJECTS16102-OOIUt1176102.001[6120/%] � - - -� �� <br />
