Sampling and Analysis Plan - Operations & Post-Operations <br />• If a micro purging (low-volume) pump is used to collect samples, the following additional <br />procedures will be implemented: <br />• Prior to installing the pumping equipment, measure and record the initial static water- <br />level in the well using a pressure transducer or water-level indicator. <br />• Slowly lower the pumping assembly into the well taking care to minimize disturbance <br />to the water column. <br />• Set the pump intake at the specific depth determined in advance (the midpoint of the <br />open interval unless geophysical logs or other information indicate otherwise). <br />• Continue to monitor and record the water level in the well to ensure that the level has <br />stabilized to the pre-pump installation level before engaging the pump to purge and <br />sample the well. <br />• Continue to monitor the water level in the well during purging and sampling and adjust <br />the purging rate as necessary so drawdown in the well is minimized (+/- 0.3 foot) and <br />does not increase over time. <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, or wiping with paper towels <br />or clean cloth; <br />2. Wash and scrub equipment with phosphate-free detergent (e.g. Alconox®, or equivalent); <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 />sampled. New peristaltic pump tubing and new 0.45 micron filters will be used for each sample <br />collected, including duplicate samples. This procedure reduces the frequency of decontamination <br />of sampling equipment. <br />• <br />American Shale Oil, LLC
