accordance with the following procedures:
(1) The well shall be sealed with a water-tight cap or well seal, as defined in G.S. 87-85
(16), compatible with the casing and installed so that it cannot be removed without
the use of hand tools or power tools.
(2) The well shall be maintained whereby it is not a source or channel of contamination
during temporary abandonment.
(b) Permanent abandonment of water supply wells other than bored or hand dug wells shall be performed in accordance with the following procedures:
(1) All casing and screen materials may be removed prior to initiation of abandonment
procedures if such removal will not cause or contribute to contamination of the
groundwaters. Any casing not grouted in accordance with 15A NCAC 02C .0107(f)
shall be removed or grouted in accordance with 15A NCAC 02C .0107(f).
(2) The entire depth of the well shall be sounded before it is sealed to ensure freedom

disinfected in accordance with Rule .0111(b)(1)(A) through .0111(b)(1)(C) of this

removed, neat-cement or bentonite slurry grout shall be injected into the well
completely filling it from the bottom of the casing to the top.
(5) Wells constructed in unconsolidated formations shall be completely filled with grout
by introducing it through a pipe extending to the bottom of the well which can be
raised as the well is filled.
(6) Wells constructed in consolidated rock formations or that penetrate zones of
consolidated rock may be filled with grout, sand, gravel or drill cuttings opposite the
zones of consolidated rock. The top of any sand, gravel or cutting fill shall terminate
at least 10 feet below the top of the consolidated rock or five feet below the bottom of
casing. Grout shall be placed beginning 10 feet below the top of the consolidated
rock or five feet below the bottom of casing in a manner to ensure complete filling of
the casing, and extend up to land surface. For any well in which the depth of casing
or the depth of the bedrock is not known or cannot be confirmed, the entire length of
the well shall be filled with grout up to land surface.
(c) For bored wells or hand dug water supply wells constructed into unconsolidated material:
(1) The well shall be disinfected in accordance with Rule .0111(b)(1)(A) through
.0111(b)(1)(C) of this Section.
(2) All plumbing or piping in the well and any other obstructions inside the well shall be
removed from the well.
(3) The uppermost three feet of well casing shall be removed from the well.

casing shall be removed, including the material extending to a width of at least 12
inches outside of the well casing.
(5) The well shall be filled to the top of the remaining casing with grout, dry clay, or
material excavated during construction of the well. If dry clay or material excavated
during construction of the well is used, it shall be emplaced in lifts no more than five
feet thick, each compacted in place prior to emplacement of the next lift.
(6) A six-inch thick concrete grout plug shall be placed on top of the remaining casing
such that it covers the entire excavated area above the top of the casing, including the
area extending to a width of at least 12 inches outside the well casing.
(7) The remainder of the well above the concrete plug shall be filled with grout or soil.
(d) All wells other than water supply wells including temporary wells, monitoring wells or test
(1) less than 20 feet in depth and which do not penetrate the water table shall be
abandoned by filling the entire well up to land surface with grout, dry clay, or
material excavated during drilling of the well and then compacted in place; and
(2) greater than 20 feet in depth or that penetrate the water table shall be abandoned by
completely filling with a bentonite or cement-type grout.
(e) Any well which acts as a source or channel of contamination shall be repaired or permanently abandoned within 30 days of receipt of notice from the Department.
(f) All wells shall be permanently abandoned in which the casing has not been installed or from which the casing has been removed, prior to removing drilling equipment from the site.
