SOP-011 Standard Operating Procedure <br />Water Level Measurements in Monitoring Wells Page 1 of 6 Revision No. 0 March 2020 <br /> <br />Sharpe Army Depot <br />1.0 Introduction <br />1.1 Purpose <br />This Standard Operating Procedure (SOP) establishes guidelines to measure the depth to water in monitoring wells. <br />1.2 Responsibilities <br />Compliance with this procedure is the responsibility of project management and field personnel. <br />Project Manager (PM). The Project Manager or Task Manager is responsible for ensuring that measurements are properly collected and documented. This will be accomplished by staff training and by maintaining quality assurance/quality control (QA/QC). <br />Contractor Quality Control Manager (CQCM). The CQCM is responsible for the periodic review of documentation generated as a result of this SOP and the periodic review and audit of field personnel as they perform the work. If problems arise, the CQCM is also responsible for verifying the implementation of corrective action(s) (i.e., retraining personnel, additional review of work plans and SOPs, variances to requirements, and issuing nonconformances) and assuring through monitoring the continued implementation of stated corrective actions. <br />Field Personnel. Field sampling personnel assigned to this task are responsible for the proper collection and documentation of the monitoring well water level measurements. <br />2.0 Relevant Documents <br />This SOP is intended to be used in conjunction with the following documents: <br />• SOP-002: Field Activity Records <br />• SOP-003: Equipment Decontamination Procedures <br />3.0 Equipment Selection <br />Several devices are available for the determination of water level measurements in monitoring wells. Those most commonly used and covered in this SOP include: <br />• Steel tapes <br />• Electric sounders <br />• Petroleum product probes. <br />The equipment must be capable of recording a measurement to the accuracy required by the project plans. Project data quality objectives and site characteristics must be taken into account when determining the water level measurement equipment to use. The total number of wells to be measured, weather, tidal influences, pumping, and construction can all affect water level measurements. The project-specific work plans will identify the specific equipment to be used.
