The wells are to be destroyed within 90 daysofthe date of this letter. <br /> Please submit a scope of work proposal that details the conditions and construction of the wells <br /> and the methods and materials to be used to destroy them. To be issued a well destruction <br /> permit, the proposal must address the concerns of the EHD and the San Joaquin County Well <br /> Standards requirements, such as: <br /> • Wells that have laboratory data from the last sampling event that demonstrate the <br /> presence of any contaminants of concern are to be destroyed by removing all the <br /> contents of the well (conductor casing; well casing, screen, filter pack, grout sealant); the <br /> cleared borehole is then to be sealed with neat cement by grouting from the bottom <br /> upward to a depth of three to five feet below grade. <br /> • All wells with unknown construction and/or located in an area of known or suspected <br /> area of contamination are to be destroyed by removing all the contents of the well <br /> (conductor casing, well casing;screen;filter--,pack; grout sealant); the cleared borehole is <br /> then to be sealed with neat cement by grouting from the bottom upward to a depth of <br /> three to five feet below grade.
