or above regulatory thresholds, sampling at DG 5 will be included in the monthly sampling and <br /> monitoring to provide additional water quality data in Yule Creek. <br /> Additional sample locations may be added as needed to aid in the monitoring of water quality in Yule <br /> Creek. Changes to the sampling schedule, frequency and/or locations will be reported to the DBMS. <br /> V. Sampling Procedures <br /> All samples will be collected by individuals experienced with water quality sampling and sent to a laboratory <br /> accredited by the National Environmental Laboratory Accreditation Program (NELAP). Sampling personnel <br /> will ensure the following procedures are followed at each sample location. <br /> A. Container Prep <br /> New un-used sample containers required by the lab for the specified analysis will be obtained the week <br /> before sampling is scheduled to ensure preservation volumes within the containers meet laboratory <br /> specifications. <br /> Sample containers will consist of the following: <br /> • (6)40 ml clear glass vials preserved with HCL <br /> • (2) 125 ml amber glass jars (no preservative) <br /> • (1) 500 ml poly(no preservative) <br /> B. Equipment Prep <br /> To reduce the risk of cross contamination, sampling personnel will ensure new un-used nitrile gloves <br /> are used during each sampling event, which includes changing gloves between each sample location. <br /> Utilizing nitrile gloves will also ensure that acid preservation within the sample bottles do not come <br /> in contact with the sampler's hand/skin. <br /> All sampling equipment (extension pole, dip rod, peristaltic pump, etc.) will be properly <br /> decontaminated between sample locations. Single use sampling equipment, such as poly jars utilized <br /> to capture low flow volumes will be triple rinsed with the water to be sampled prior to collection and <br /> transfer. All single use containers will be discarded after each use. <br /> Sample coolers will contain the necessary volume of ice to preserve sample containers to 4° F and <br /> each cooler will contain a temperature and trip blank to accompany the samples to the lab. <br /> In-stream flow meter readings will be collected at each sample location utilizing a Global Water Flow <br /> Probe (Model FP101)and will record the average and max flow volumes in ft/sec. In instances where <br /> a sampling extension pole is needed to collect a sample due to high flow volumes, ice danger,or other <br /> unforeseen circumstances, flow volumes will not be recorded for that sample location. <br /> All water quality readings will be collected utilizing a YSI 556 MPS water quality meter. Equipment <br /> will be calibrated prior to use to ensure accuracy of readings collected. Field parameters will be <br /> recorded on a surface water data sheet and transferred to a master tracking spreadsheet for trend <br /> analysis. If conditions (freezing, fast runoff, presence of free phase product, etc.) are present, then <br /> 4 <br />
