Standard Operating Procedure Page 1 of 6 <br /> SOP-011 Water Level Measurements in Monitoring Wells Revision No. 0 <br /> March 2020 <br /> 1.0 Introduction <br /> 1.1 Purpose <br /> This Standard Operating Procedure (SOP) establishes guidelines to measure the depth to water in <br /> 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 <br /> measurements are properly collected and documented.This will be accomplished by staff training and by <br /> maintaining quality assurance/quality control (QA/QC). <br /> Contractor Quality Control Manager (CQCM). The CQCM is responsible for the periodic review of <br /> documentation generated as a result of this SOP and the periodic review and audit of field personnel as <br /> they perform the work. If problems arise, the CQCM is also responsible for verifying the implementation <br /> of corrective action(s) (i.e., retraining personnel, additional review of work plans and SOPs' variances to <br /> requirements, and issuing nonconformances) and assuring through monitoring the continued <br /> implementation of stated corrective actions. <br /> Field Personnel. Field sampling personnel assigned to this task are responsible for the proper collection <br /> 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. <br /> 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 <br /> plans. Project data quality objectives and site characteristics must be taken into account when <br /> determining the water level measurement equipment to use.The total number of wells to be measured, <br /> weather, tidal influences, pumping, and construction can all affect water level measurements. The <br /> project-specific work plans will identify the specific equipment to be used. <br /> Sharpe Army Depot <br />
