APPENDIX C <br /> Diamond Pet Food Processors of Ripon,LLC June 30,2011 <br /> Report of Waste Discharge—Groundwater Sampling Plan Page 3 of 7 <br /> situation, measurement of indicator parameters at one (1) minute intervals would be appropriate. The <br /> following purging procedures will be followed: <br /> • The pumping rate and the depth to water will be recorded on the Field Sampling Data Sheet <br /> (FSDS). <br /> • Field water quality parameters will consist of pH, temperature, turbidity, and specific <br /> conductance. Field parameters and purge volume will be recorded on the FSDS. <br /> After the water-level has stabilized in the well and the groundwater quality field parameters have <br /> stabilized, groundwater samples will be collected directly from the discharge tube of the pump,using <br /> laboratory-supplied containers. <br /> EQUIPMENT CLEANING AND DECONTAMINATION <br /> If dedicated sampling equipment is not used, nondedicated equipment used to collect groundwater <br /> samples must be decontaminated using the procedures below. All nondedicated groundwater <br /> sampling equipment and newly installed pumps will be decontaminated in the following sequence <br /> before samples are collected at any monitoring well or leachate sampling location: <br /> • Rinse with tap or distilled water. <br /> • Wash with nonphosphatic detergent consisting of a dilute mixture of Liquinox (or its <br /> equivalent) and tap or distilled water. <br /> • Rinse with distilled water. <br /> SAMPLE HANDLING AND PRESERVATION <br /> The sample containers will be prepared and provided by the analytical laboratory. Samples must be <br /> properly and carefully handled to ensure that they are representative of the sampled media. <br /> Samples will be preserved consistent with the laboratory procedures. <br /> SAMPLE STORAGE AND SHIPPING <br /> Before packing the sample bottles into the shipment coolers, the sampler must record the sample <br /> designations in the appropriate place on the FSDS and chain-of-custody form. Sample containers <br /> should be placed in an iced cooler(approximately 4°C) immediately after sample collection. Sample <br /> containers must be kept closed, maintained under custody, and cooled until the sample is analyzed. <br /> Recommended holding times from when samples are collected until sample analysis should not be <br /> exceeded. <br /> 010070.00, Task I Lawrence&Associates <br /> w:Iclientsldiamond pet foods1010107.00-ripon rowdldiamondpet_rowd_june2011 draft.docx <br />
