Sampling and Analysis Plan - Operations & Post-Operations 0 For the wells at which samples are to be collected using conventional pumping, a dedicated pump (1 to 5 horsepower), associated discharge piping, and power cable will be installed in each monitoring well. The downhole assembly will be secured at the well head within a locked steel cover. A portable generator will be used to supply power for the pumps. For the wells at which samples are to be collected using nitrogen lifting or micro-purging (low- volume) techniques, the proper assembly will be installed in each monitoring well. Groundwater sampling will be accomplished in accordance with the following procedures: • Portable meters used to measure field parameters (pH, conductivity and temperature, oxidation-reduction potential (ORP), dissolved oxygen, and turbidity) will be calibrated daily prior to collection of the first sample. Calibration will be performed in accordance with manufacturers' specifications. • The wellhead discharge piping assembly will be connected to the discharge pipe at the wellhead. The total volume of water purged from the well will be measured using a totalizing inline flow meter or calibrated equipment (e.g., tank or bucket). • Any electrical connections will use all-weather electric cables. All electrical equipment • will be grounded and fit with ground fault interruption protection. • If a totalizing inline flow meter is used, the initial flow meter reading will be recorded prior to removing any water from the well. • The submersible pumping, nitrogen lifting, or micro-purging equipment will be engaged to initiate purging water from the well. If submersible pumps are used, all wells on the pad undergoing sampling will be purged simultaneously, if possible. • A portion of the flow from the well will be diverted through the sample port on the wellhead assembly to measure field parameters. Field parameters will be measured initially after the submersible pump, nitrogen lifting, or micro-purging equipment is engaged and periodically depending on discharge rate as follows: o Submersible pump - approximately every 30 minutes o Nitrogen lift - each lift o Micro-purge - approximately every 5-10 minutes • Flow rate from the well will be measured from inline meter readings and/or at the end of the discharge pipe or hose using a calibrated bucket and stop-watch. At a minimum, measurements will be taken initially after the submersible pump, nitrogen lift, or micro- purge equipment is engaged, periodically (5 to 20 minutes) during the purging phase, and immediately before and after sample collection. • American Shale Oil, LLC 7
