The <br /> County has specified that an extraction well be placed within the tank pit. The <br /> downgradient extraction well location has also been moved westward about 30 feet <br /> to be close' to the tankpit with respect to contaminant levels and possibly varying, <br /> groundwater flow conditions (Figure 2). <br /> This fourth well (MW-8) will be drilled, sampled, and installed in the same manner, <br /> and with the sarne tools and materials as the other wells within this project. These <br /> tools, processes, and materials are described in the previously submitted, April 20, <br /> 1995 workplan. MW-8 will be a 4 inch well installed with the idea of possibly <br /> removing free product or groundwater from MW-8 as part of a remediation system. <br /> Please call us at (510)4~39-1024 if you have any questions or comments. <br /> ti Sincerely, <br /> PARKER ENVIRONMENTAL SERVICES <br /> jamas D.
