Sampling and Analysis Plan <br />• Once field parameters have stabilized and the appropriate volume of water has been <br />purged from the well, water quality samples will be collected for laboratory analysis. <br />Samples will be collected as follows: <br />o Field parameters will be measured and recorded immediately prior to sample <br />collection. <br />o Samples will be collected by diverting a portion of the flow from the well <br />through the sample port and directly into the sample containers. Flow through <br />the port will be reduced to ensure low, even flow. <br />o Care will be taken to not overfill containers containing preservative. <br />o When required, samples will be filtered in the field by using a portable peristaltic <br />pump and 0.45 micron disposable filters. When filtering, a clean transfer <br />container will be used to fill other sample bottles. <br />o Sample labels showing the sample number, date, time of collection, and <br />sampler(s) initials will be affixed to each sample bottle. <br />o Sample containers will be placed on ice in a sample cooler for storage and <br />shipment to the laboratory; glass containers will be protected to avoid breakage <br />during shipment. <br />o Field documentation will be recorded on the Groundwater Sampling Form <br />(Appendix B). <br />o Chain-of-Custody records will be properly completed and signed at the time the <br />samples containers are delivered for shipment to the laboratory. <br />4.0 Decontamination Procedures <br />All re-useable sampling equipment will be decontaminated prior to sample collection. This <br />includes bulk containers to collect water for field filtration and any other equipment that will be <br />re-used. The following decontamination procedure will be used: <br />1. Removed gross contamination from equipment by brushing; <br />2. Wash and scrub equipment with phosphate-free detergent; <br />3. Rinse equipment with distilled water; and <br />4. Air-dry or wipe equipment with clean paper towels. <br />Prior to sample collection, bottles used to collect a bulk volume of water to be transferred to <br />laboratory sample bottles will be rinsed with distilled water then triple rinsed with the water to be <br />American Shale Oil, LLC 8
