Sampling and Analysis Plan <br />• Check that a measurement mark has been placed on top of the well casing; for <br />consistency, the measurement marks will be placed on the north side of the casing. If the <br />mark has worn off, re-mark the casing. <br />• Measure the height of the well casing (stick-up) as the distance from the top of the casing <br />to the ground surface. <br />• Perform battery check to ensure water-level indicator is functioning properly. <br />• Lower probe into well until static water level is encountered, signified with audible alarm <br />and indicator light. <br />• Read depth to water as measured to the top of the well casing at the marked measuring <br />point. <br />• Record date, time, well stick-up, and measured depth to water in bound field logbook. <br />• Retrieve probe from well; use wetted clean cloth to clean tape as it is retrieved from the <br />well. <br />• Decontaminate water-level probe with solution of Alconox® and clean water followed by <br />clean water rinse. <br />In the case that electronic pressure transducers or in situ loggers are used, the indicated pressure <br />(water level) or stored data will be downloaded to a laptop computer using vendor-provided <br />software and conventional electronic data-transfer methods. <br />3.3.2 Groundwater Sampling <br />AMSO anticipates that sampling of groundwater wells will be conducted by conventional <br />pumping, nitrogen lifting, and/or micro-purging techniques. This SAP describes general <br />sampling techniques to be implemented for the monitoring program. However, through the <br />course of subsurface investigations, AMSO may determine that other, more advantageous or <br />effective methods of sampling may be appropriate. <br />For the wells at which samples are to be collected using conventional pumping, a dedicated pump <br />(1 to 5 horsepower), associated discharge piping, and power cable will be installed in each <br />monitoring well. The downhole assembly will be secured at the well head within a locked steel <br />cover. A portable generator will be used to supply power for the pumps. <br />American Shale Oil, LLC 6
