(A) A well to be temporarily abandoned, but which the owner intends to equip and use at some future time, shall be temporarily sealed at the surface by a welded or threaded cap or in the case of a dug well in a manner satisfactory to the Health Officer.
(B) A well shall be properly abandoned if the well has not been in service for two years. Proper abandonment is plugging the well. The following methods apply.
(1) Cement and bentonite slurries shall be pumped into place in a continuous operation with a grout pipe introducing the plugging material at the bottom of the well and moving the pipe progressively upward as the well is filled.
(2) Plugging materials other than neat cement or bentonite shiny shall be installed in a manner to prevent bridging of the well or borehole. The well or borehole shall be measured periodically throughout the plugging process to ensure that bridging does not occur.
(3) The following procedures apply.
(a) An abandoned well shall be disconnected from the water system. Any substance that may interfere with plugging shall be removed, if practicable.
(b) A well shall be chlorinated before abandonment as provided in 312 I.A.C. 13-9-1.
(C) Dewatering wells, temporary service wells, construction water wells, process wells and/or other structures for withdrawing groundwater or lowering of water levels or water tables regardless of location, length of intended service or original use or intent, shall be constructed to the identical standards and minimums as water supply wells contemplated by this chapter.
(D) The abandonment of dewatering wells, construction wells and temporary wells shall be accomplished via the identical procedure prescribed herein for permanent abandonment.
