This document <br />describes the materials and procedures required, and serves as a supplement to the groundwater and <br />surface water monitoring plan. <br />The objective of measuring ("sounding") water levels is to determine the change, if any, in <br />water level elevation over time. Electronic water level sounders and dedicated pressure transducers <br />will be used, Water level measurement with an electronic sounder will be conducted as described <br />in this SOP. Water level measurement with a pressure transducer should be conducted in accordance <br />with the transducer manufacturer's operation and calibration instructions. <br />C~ <br />J <br />B.2 EQUIPMENT <br />Equipment needed to measure water levels may include: <br />Maps with well locations. <br />Well completion data. <br />~ Keys to protective well covers. <br />Electronic water level sounder. <br />~ Engineer's tape. <br />~ Decontamination equipment. <br />B.3 PREPARATION <br />The following actions are recommended before going to the field to sound water levels: <br />Test equipment prior to departing for field. Are the batteries fresh? Does the sensor <br />work when probe is immersed in water? <br />• <br />Agapito .Associates, Inc. <br /> <br />
