Kennedy/Jenks Consultants <br /> Appendix E: Standard Operating Guideline <br /> Groundwater Sampling <br /> E.1 Introduction <br /> This guideline describes procedures typically followed by Kennedy/Jenks Consultants <br /> (Kennedy/Jenks) personnel during groundwater sampling of monitoring wells. <br /> E.2 Equipment/Materials <br /> • Water level depth probe <br /> Laboratory-cleaned or sanitized disposable bailers with disposable cord <br /> • Submersible pump <br /> Temperature and specific conductivity meter <br /> • pH meter <br /> • Appropriate glassware and sample containers <br /> Kennedy/Jenks Groundwater Purge and Sample Form (F-43) <br /> E.3 Typical Procedure <br /> All data and information collected during this procedure shall be recorded on Kennedy/Jenks' <br /> Groundwater Purge and Sample Form (F-43). <br /> 1. Prior to groundwater sampling, make initial measurements of depth to static water level and <br /> total casing depth in all wells to be sampled. Calculate the total well volume of water for purge <br /> volumes for each well. <br /> 2. Initiate purging, using one of the following methods: <br /> Laboratory-cleaned or disposable bailers. <br /> A submersible pump placed at the well screen depth. A check valve is to be placed above <br /> the submersible pump. <br /> If possible, use disposable, flexible tubing. <br /> 3. At the beginning of purging, and periodically afterwards, collect a sample of purged groundwater <br /> in a clean container and record the following field parameters/observations. <br /> Purge volume and time <br /> Temperature <br /> pH <br /> Specific conductance <br /> Work Plan for Improved Detection Monitoring Program Appendix E <br /> Musco Family Olive Company, Tracy, California Page E-1 <br /> g.sy.piedm mIOM2010400-mus=m OINg pa ktd 27_dm Wpwdims Vpdxe doc <br />
