PROTOCOL <br /> WATER LEVEL, WELL DEPTH, AND FLOATING PRODUCT MEASUREMENTS <br /> 1.0 INTRODUCTION <br /> This protocol describes the procedures to be followed during water level, well depth, and free <br /> product measurements. The procedures presented herein are intended to be of general use and <br /> may be supplemented by a work plan and/or health and safety plan. As the work progresses <br /> and if warranted, appropriate revisions may be made by the project manager. Detailed <br /> procedures in this protocol may be superseded by applicable regulatory requirements. <br /> 2.0 WATER LEVEL AND WELL DEPTH MEASUREMENTS <br /> A DAILY FIELD RECORD will be completed for each day of fieldwork. Water levels will <br /> be recorded on a WATER LEVEL MONITORING RECORD. Following review by the <br /> project manager, the original records will be kept in the project files. <br /> Water level measurements at a site will be taken as quickly as practical, to best represent the <br /> potentiometric surface across the site at a single time. If pressure is suspected or has <br /> developed inside the well casing, the well will be allowed to stand without a cap for a few <br /> minutes or until the water level stabilizes before taking the water level measurement. Water <br /> level measurements will be recorded to the nearest hundredth (0.01) foot, and well depth <br /> measurements will be noted to at least the nearest half(0.5) foot. Equipment placed in the <br /> wells for water level and well depth measurements will be cleaned prior to reuse, as discussed <br /> in Section 4.0. Care will be taken not to drop foreign objects into the wells and not to allow <br /> the tape or sounding device to touch the ground around the well during monitoring. <br /> WATER LEVEL, WELL DEPTH, AND FREE FLOATING MEASUREMENTS Page 1 of 6 <br /> MSCIPROTO-WL_TXT REVISION DATE:MARCH 1996 WL-1 <br />
