(Delta), as, authorized by Ultramar Inc., destroyed a domestic <br /> water supply well at the above-referenced site on October 14, 1992. Destruction of the well was a <br /> prerequisite to connecting facilities at the site to the City of Lodi water supply system. The work was <br /> approved by your office under Well Permit No. 92-3447. The location of the site is shown in <br /> Figure I and the previous location of the domestic water supply well is shown in Figure 2. <br /> Construction details reported to Delta indicated that the well was 144 feet deep with a 6-inch <br /> diameter, unscreened, open-bottom steel casing to a depth of 120 feet. After removal of the wellhead <br /> assembly and submersible pump, the well was found to be free of obstructions to a depth of 142 feet <br /> below grade. The depth to water in the well was approximately 57.5 feet below grade. The well <br /> was destroyed by backfilling with a 9 sack sand-cement grout. The grout was emplaced from the <br /> bottom up by pumping through a tremie pipe to prevent dilution or bridging. The well was grouted <br /> to within 1.5 feet of the ground surface. <br /> The calculated volume of the well was approximately I cubic yard. The actual volume of grout used <br /> was approximately 3.5 cubic yards, indicating that the well and void space in the adjacent formation <br /> were adequately seated. <br /> Delta Delivers Solutions <br />
