Sampling <br /> 1) Depth Measurement: The static water level of the groundwater well will be measured <br /> and recorded using a water level well sounder prior to pumping of the well. The <br /> measurement location at the top edge of the well casing will be marked with a <br /> permanent ink pen. This mark will be touched up with fresh ink each time a sample is <br /> taken. <br /> 2) Purging the well: The contents of the well will be purged prior to sample collection <br /> using a low-flow, submersible pump. This pump will be cleaned prior to being placed in <br /> the well. Sampling will not occur until conditions of the water have stabilized AND at <br /> least three well volumes have been removed from the well. If the required volume has <br /> been purged, and the water appears to not be stabilized, then additional purging must <br /> occur until stabilization. Stabilization of the groundwater can be determined based on the <br /> following: <br /> a. Water is running clear with little to no sediment for a prolonged period of time. <br /> b. Field measurements, such as those listed below, have stabilized. <br /> 3) Field Measurements: Water will be collected in a clean and empty container for various <br /> field measurements. Between sampling locations, the container must be cleaned or <br /> rinsed thoroughly, preferably with water from the source to be sampled next. The <br /> following field measurements will be taken with cleaned and calibrated meters. Field <br /> measurements will be reported in a manner that is consistent with industry standards for <br /> field sampling logbooks. An example of the logbook to be used is shown in Appendix 4. <br /> a. pH <br /> b. Temperature <br /> c. Dissolved Oxygen <br /> d. Conductivity <br /> 4) Collecting Samples: Water will be pumped from the well into a clean pitcher or bottle <br /> which will be used to fill the bottles from the laboratory. The bottles will be marked with <br /> the date, time, and site location of the sample as well as the person who collected the <br /> sample. If a pump controller system is used, the sample bottles may be filled directly <br /> from the well. Samples will be preserved and shipped in accordance with the method <br /> requirements. Filled sample bottles will then be placed in a cooler with ice for transport <br /> to the lab. <br /> 5) Contamination Prevention: Special care must be exercised to prevent contamination <br /> of samples. Samples must be stored in a secure location to prevent alteration of the <br /> sample properties. The chain of custody procedure must be followed. Sampling shall <br /> occur from the least contaminated, to the most contaminated location. <br /> 6) Chain of Custody: A chain of custody will be completed for the sample which indicates <br /> what analyses need to be performed, the date and time of sampling, sample <br /> identification, and who assembled the sample. The samples will be delivered to the lab <br /> the day of collection. Samples shall be custody sealed during shipment or long term <br /> storage. Sampled must remain in the custody of the sampler sample custodian until the <br /> samples are relinquished to the laboratory. <br /> North Hangs Mine GW Monitoring <br /> Plan 11 Lewicki& Associates <br /> December 2024 <br />
