f > drilling. San Joaquin Co. 01 standards, 13.17.6, essenti'a*y state <br /> > that overdrilling shall be used if the monitoring well is located in an <br /> > area of known contamination. Well BC-1 is a vadose zone well. Wells <br /> > BC-12 and RW-1 are both screened in a chloroform plume, but the reported <br /> > chloroform concentration is quite low, currently from 16 to 21 <br /> > micrograms per liter. This concentration range is below the drinking <br /> > water MCL. I am preparing the work plan for review by the Regional <br /> > Board now. From a County perspective, would it be acceptable to abandon <br /> > any or all of these wells by pressure grouting, and thereby save our <br /> > client $? Incidentally, well BC-12 is in some guy's front yard, and it <br /> > would be nice to avoid a heavy drill rig in that location. I can fax <br /> > you the well construction diagrams if that will help. <br /> > Thank you, <br /> > Rob Hammond, AME Inc. <br /> 2 <br />
