r <br /> GEQMATRIX <br /> PROTOCOL <br /> INSTALLATION AND DESTRUCTION OF WELLS <br /> 1.0 INTRODUCTION <br /> This protocol describes procedures to be followed during the installation or destruction of <br /> monitoring, groundwater extraction, and vapor extraction wells. The procedures presented <br /> :herein are.intended to be of general use. As the work progresses, and if warranted <br /> g P g , <br /> appropriate revisions will be made and approved by the project manager. Detailed <br /> procedures in this protocol may be superceded by applicable regulatory requirements. <br /> 2.0 WELL INSTALLATION <br /> . If required, permits for the installation of wells will be acquired from the appropriate <br /> regulatory agency before drilling is initiated. After well installation, well completion <br /> report(s) will be completed and filed with the California State Department of Water <br /> Resources or the appropriate agency. <br /> Each groundwater monitoring well will be designed to enable measurement of the potentio- <br /> ,,,� .metric surface and to permit water sampling of a specific water-bearing zone. Each vapor <br /> monitoring well will be designed to enable measurement of pressure conditions and permit <br /> sampling of a specific zone. The field geologist/engineer, in consultation with the project <br /> Geologist or Engineer who will be registered with the State of California if required, will <br /> specify the screened interval using the lithologic log and geophysical log (if performed) and <br /> will select the well materials and techniques for well completion to be compatible with the <br /> formations and the intended use of the well. Drilling and logging of the borings for the <br /> wells will be in conformance with the protocol DRILLING OF SOIL BORINGS. <br /> I' INSTALLATION AND DESTRUCTION OF WELLS <br /> MSC�GEOMATRX.PRO REVISION DATE:NOVEMBER 1992 p <br /> Page 1 of Q <br /> I �` <br />
