APPENDIX C Diamond Pet Food Processors of Ripon,LLC June 30,2011 Report of Waste Discharge—Groundwater Sampling Plan Page 4 of 7 To comply with packaging regulations and to take practical measures to prevent damaging samples, the sampling personnel will follow packaging and shipping instructions supplied by the certified testing laboratory. The chain of custody form for the samples in the container will be placed inside the cooler. On receipt, the laboratory will note on the chain of custody form the temperature of the samples and any evidence of damage or tampering. SAMPLING DOCUMENTATION It is essential that all sampling activities be documented on a FSDS. Entries should be made in indelible ink and changed by crossing out the entry with a single line and initialing it. The data recorded on a FSDS depends on the sampling activity being performed and will include some or all of the following: • Facility name; • Date; • Sampler's name and signature; • Sample type; • Sample identification; • Weather(ambient temperature, wind condition, etc.); • Field instrument calibration; • Field measurements (water level, pH, conductivity,temperature, and turbidity; • Field calculations (such as well purge volumes); • Number, volume, and type of sample containers; • Condition of the sample location(monitor well, riser pipe, etc.); and • Any unusual conditions that may affect samples or any deviations from the normal sampling protocol. To help maintain the integrity of the samples, strict chain-of-custody procedures will be implemented. These procedures will help ensure that tampering of samples does not occur. The chain-of-custody form is a manifest of the sample containers and describes the analyses to be performed on the samples in each container. All sample containers will be clearly and unambiguously labeled and chain of custody forms will be completed before the end of each sampling day. A written record of the sample bottle possession and any transfer of the samples must be maintained and documented on the chain of custody record. The chain-of-custody forms and relevant FSDSs will be sent with the samples to the laboratory. Copies of FSDSs, chain of custody forms, and air bills or shipping manifests will be retained in the site files. 010070.00, Task I Lawrence&Associates w:Iclientsldiamond pet foods1010107.00-ripon rowdldiamondpet_rowd_june2011 draft.docx
