rt <br /> T <br /> Kennedy/Jenks Consultants <br /> Appendix C: Standard Operating Guideline <br /> Surface Water Sampling <br /> Introduction <br /> r ? <br /> This guideline describes field procedures typically followed by Kennedy/Jenks Consultants <br /> personnel to obtain surface water samples. Methods of sampling are directly affected by study <br /> objectives and parameters that are to be analyzed. To help ensure efficient sampling and useful <br /> results, decisions regarding g g a ppropriate techniques and equipment employed must be made at the <br /> beginning of a project. <br /> � r <br /> Equipment <br /> • Appropriately preserved sample containers and caps as provided by the laboratory. Containers <br /> should be clean and of appropriate type and size for the chemical component sampled. <br /> • Container labels and waterproof marking pens. <br /> • Manual sample retrieval equipment. This equipment can include a scoop or container for <br /> surface sampling. <br /> • Waterproof field notebook. <br /> • Ice chest with sufficient blue ice to last for the duration of sampling and transport. <br /> • Packing materials for transport. <br /> • Portable analytical equipment, if necessary (pH, DO, conductivity, temperature, etc.). <br /> • Chain-of-custody forms. <br /> Typical Procedures <br /> � e <br /> 1. Consult with the laboratory regarding sampling procedures, type and size of containers <br /> required, sample preservatives, holding times, and shipping recommendations. <br /> 2. Prepare a sample bottle (if it does not already contain a preservative) by rinsing it out two or <br /> three times with the water to be collected. <br /> 3. Treat each sample individually with regard to the substances to be determined. In other words, <br /> use the recommended preservative and container for the particular substance of interest. <br /> 4. For most samples, fill the container completely. Space can be left for some microbiological <br /> analyses. For samples that are to be shipped, leave an air space of about 1 percent of the <br /> container to allow for thermal expansion. For volatile and semi-volatile analysis, no headspace <br /> should be allowed. <br /> Crop Uptake and Assimilative Capacity Work Plan, 1 <br /> Woodbridge Winery, Acampo, California <br />
