The top <br /> f three feet were grouted with <br /> a neat cement mixture. <br /> The surface protective cover for each well was removed, and the well was either drilled out or <br /> pressure grouted as described above. Following over drilling and/or pressure grouting, each <br /> well was finished at the surface to match the current surface conditions. Over drilling was <br /> U performed using a CME hollow stem auger drill rig. Well abandonment activities were <br /> performed in accordance with San Joaquin County and Department of Water Resources <br /> Lj (DWR) guidelines.
