Sampling and Analysis Plan - Operations & Post-Operations <br />• In the case that a water-level indicator tape is used, measurement will proceed as follows: <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. The <br />mark should preferably be permanent, such as notched etch with a file. If the mark has <br />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 />• Assure that the water-level indicator (probe) has been decontaminated <br />• Perform battery check to ensure water-level indicator is functioning properly. <br />• Lower the probe into well until static water level is encountered, signified with audible <br />alarm and indicator light. <br />• Read depth to water as measured to the top of the well casing at the marked measuring <br />point to the closest one hundredth of a foot (0.01 ft). <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®, or equivalent, and clean <br />water followed by 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. Pressure transducers will be <br />decontaminated prior to deployment to a well. <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 (low-volume) techniques. This SAP describes <br />general sampling techniques to be implemented for the monitoring program. However, through <br />the course of subsurface investigations, AMSO may determine that other, more advantageous or <br />effective methods of sampling may be appropriate. <br />American Shale Oil, LLC 6
