Sampling and Analysis Plan - Operations & Post-Operations • • Sampling personnel will make note of the gas production at each well and monitor the H2S and lower explosive limit (LEL) levels encountered during purging. • An appropriate volume of water will be purged from the well before sample collection; however, samples will not be collected until field parameters of pH, specific conductance, and temperature have generally stabilized from three consecutive rounds of parameter measurements. o if micro-purging method is used to purge and sample the well, a minimum of one tubing volume (including pump and flow-through cell) will be purged from the well prior to recording water-quality indicator parameters. The parameters will then be recorded at specific intervals determined on the basis of tubing volume, pumping rate, and drawdown. Groundwater samples will be collected after three successive readings of the parameters have stabilized. • Once field parameters have stabilized and the appropriate volume of water has been purged from the well, water quality samples will be collected for laboratory analysis. Samples will be collected as follows: o Field parameters will be measured and recorded immediately prior to and after sample collection. o Samples will be collected by diverting a portion of the flow from the well through the sample port and directly into the sample containers. Flow through • the port will be reduced to ensure low, even flow. o Care will be taken to not overfill containers containing preservative. o When required, samples will be filtered in the field. When sufficient pressure is available at the well head, filtration will be conducted by attaching new flexible sample tubing and 0.45 micron disposable filter directly to the sample port. If pressure is too low, a portable peristaltic pump will be used with the flexible tubing and 0.45 micron disposable filter to pump from a clean transfer container and fill sample bottles. o Sample labels showing the sample number, date, time of collection, and sampler(s) initials will be affixed to each sample bottle. o Sample containers will be placed on ice in a sample cooler for storage and shipment to the laboratory; glass containers will be protected to avoid breakage during shipment. o Field documentation will be recorded on the Groundwater Sampling Form (Appendix B). o Chain-of-Custody records will be properly completed and signed at the time the samples containers are delivered for shipment to the laboratory. 0 American Shale Oil, LLC 8
