Common use of Sampling Procedures Clause in Contracts

Sampling Procedures. Equipment and Supplies. The following equipment and supplies will be necessary for the collection of water samples by the Provider: Sample Collection Training. Provider shall ensure trained individuals perform the collection of samples. Within 15 days after Contract execution, Provider must submit a brief description of the training of the individuals to the Beach Watch Coordinator. Sample Collection. One sample will be collected at each station. For every 10 stations sampled on any given day, a second sample must be collected at one of the stations as required by the QAPP. Samples shall be collected within arm’s length of each other. Sample collection may be done side-by-side or concurrently. All water samples shall be collected as follows: Step-by-Step Procedures for Local Contractors. The following procedures for sampling are based upon text taken from Part II, Section A, of the EPA publication "Microbiological Methods for Monitoring the Environment: Water and Wastes" EPA-600/8-78-017, December 1978. 1. Identify the sampling site on a chain of custody tag, if required, or on the bottle label and on a field log sheet. 2. Remove the bottle covering and closure just before obtaining each sample and protect them from contamination. Be careful not to touch the inside of the bottle itself or the inside of the cover. 3. The first sample to be prepared is the trip blank (at least one per sampling day for routine sampling is recommended). Open the sampling bottle and fill it with 100 ml of sterile buffered dilution solution when collecting freshwater, estuarine, or marine water samples. Cap the bottle and place it in a cooler. The trip blank will be used to verify samples have been maintained at the correct temperature for transportation. 4. To collect the water samples, carefully move to the first sampling location. If wading in the water, try to avoid kicking up bottom material at the sampling station. The sampler should be positioned downstream of any water current to take the sample from the incoming flow. Samples shall be collected in approximately two feet of water. 6. Remove the bottle from the water body. 7. Pour out a small portion of the sample to allow an air space of 2.5 centimeters (1 to 2 inches) above each sample for proper mixing of the sample before analysis. [NOTE: If the bottle contains any debris, contaminants, or excessive sediment/sand, a new bottle must be used. Do not discard the water sample and refill the bottle.] 8. Tightly close the stopper and label the bottle. 9. Enter specific details to identify the sample on a permanent label. Take care in transcribing sampling information to the label. The label should be clean, waterproof, non-smearing, and large enough for the necessary information. The label must be securely attached to the sample bottle but removable when necessary. Preprinting standard information on the label can save time in the field. The marking pen or other device must be non-smearing and maintain a permanent legible mark. 10. Complete a Field Observation Form (FOF) for each beach to record the full details on sampling and other pertinent remarks, such as flooding, rain, or extreme temperature, that are relevant to interpretation of the results. This record also provides a back-up record of sample identification. 11. Place the samples in a suitable container and transport them to the laboratory as soon as possible. Adhering to sample preservation and holding time limits is critical to the production of valid data. Bacteriological samples should be iced or refrigerated at <10°C during transit to the laboratory. Use insulated containers such as plastic or Styrofoam coolers, if possible, to ensure proper maintenance of storage temperature. Take care to ensure sample bottles are not totally immersed in water during transit or storage. Process samples as soon as possible after collection. Do not hold samples longer than six hours between collection and initiation of analysis (US Environmental Protection Agency, 2000). Do not analyze samples that exceed holding time limits. 12. Collect water samples for analyses of other parameters in separate appropriate containers at the same time and perform analyses as specified in the methods. 13. After collecting samples from a station, wash hands and arms with alcohol wipes, a disinfectant lotion, or soap and water, and dry to reduce exposure to potentially harmful bacteria or other microorganisms. • Date and time of sample collection • Sampler’s name • Sample letters and station number as identified in Appendix C of the QAPP (identify the first sample with the letter “A” after the station number, the second sample with the letter “B” and so forth)

Samples shall be collected in approximately two feet of water. 5. Open a sampling bottle, grasp it at the base with one hand, and plunge the bottle mouth downward at 90 degrees into the water to avoid introducing surface scum. Position the mouth of the bottle into the current away from the hand of the sampler. The sampling depth should be 15 to 30 centimeters (6 to 12 inches) below the water surface, depending on the depth from which the sample must be taken. Samples collected in less than the two-foot standing depth will collect the sample at the 15- centimeter (six inch) sampling depth to avoid the collection of sedimentation. Allow time for sediment settling prior to collecting the sample. If the water body is static, an artificial current can be created by moving the bottle horizontally with the direction of the bottle pointed away from the sampler. Tip the bottle slightly upward to allow air to exit and the bottle to fill. 6. Remove the bottle from the water body. 7.
