(A) Every well shall be maintained in a condition whereby it will not be a source or channel of contamination or pollution to the water supply, or any aquifer.
(B) All materials used in the maintenance, replacement, or repair of any well shall meet the requirements for new installation.
(C) Broken, punctured, or otherwise defective or unserviceable casing, screens, fixtures, seals, or any part of the well head shall be repaired or replaced, as soon as possible, or the well shall be permanently abandoned.
(D) Repairs to wells completed with the well head terminating below ground (buried seal) shall include extending the well casing above land surface. The Health Department shall not approve any well having an entry below land surface. The extension shall be made as follows:
(1) A tapered sleeve shall be inserted inside of the casing and shall extend at least six inches down into the existing casing. The extension casing shall be welded or bonded to the existing casing around the outside of the joint; or
(2) A sleeve shall be heated and swedged over the existing casing with at least six inches of overlap.
(E) Cement grout shall be placed around the casing, extending from land surface to a depth of at least one foot below the joint formed by the casings. The grout shall have a minimum thickness of one and five-tenths inches.
(F) National Sanitation Foundation (NSF) approved PVC pipe rated at 160 PSI may be used for liner casing. The liner casing shall be installed with centering guides to ensure proper centering in the well. The annular space around the liner casing shall be at least five-eighths inches and shall be completely filled with neat-cement grout.
(Ord. passed 7-23-1984)
(A) Every well whose use or construction has been discontinued, either temporarily or permanently, shall be abandoned in accordance with these regulations.
(B) When any well is temporarily removed from service or before any well is put into service, it shall be sealed with a watertight cap or seal.
(C) The well shall be maintained whereby it is not a source or channel of contamination during temporary abandonment.
(D) Every temporarily abandoned well shall be protected with a casing.
(E) Any well that is a source or channel of contamination shall be repaired or permanently abandoned within 30 days of receipt of an order from the Health Department.
(F) The drilling contractor shall permanently abandon any well in which the casing has not been installed or from which the casing has been removed, before removing his or her equipment from the site.
(G) Any well not in compliance with the conditions for temporary abandonment shall be brought into compliance or permanently abandoned within 30 days or receipt of notice from the Health Department.
(H) The well owner shall be responsible for permanent abandonment of a well except:
(1) As otherwise specified in these regulations; or
(2) If well abandoned is required because the driller improperly locates, constructs, or completes the well, in which case the driller is responsible for abandoning the well.
(I) Permanent abandonment procedures include the following.
(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 ground waters.
(2) In the case of gravel-packed wells in which the casing and screens have not been removed, the casing shall be perforated opposite the gravel pack at intervals not exceeding ten feet and grout injected through the perforations under pressures, or neat cement shall be injected into the gravel by washing a line to the bottom of the gravel and pumping the cement in from the bottom up into the gravel until a return is obtained at the top through the gravel.
(3) The well shall be checked from land surface to the entire depth of the well before it is sealed to ensure freedom from obstructions that may interfere with sealing operations.
(4) The well shall be thoroughly chlorinated before sealing.
(5) “Bored” wells shall be completely filled with cement grout, dry clay, or material excavated during drilling of the well and shall be compacted in place.
(6) Wells constructed in unconsolidated formation other than”bored” wells shall be completely filled with cement grout by introducing it through a pipe extending to the bottom of the well which can be raised as the well is filled.
(7) Wells constructed in consolidated rock formations or that penetrate zones of consolidated rock may be filled with cement, sand, gravel, or drill cuttings opposite the zones of consolidated rock, the top of the sand, gravel, or cuttings fill shall be at least five feet below the top of the consolidated rock, the remainder of the well shall be filled with cement grout only.
(8) Test wells less than 20 feet in depth that do not penetrate the water table shall be abandoned in such a manner as to prevent the well from being a channel allowing the vertical movement of water or a source of contamination to the ground-water supply. Test wells or borings that penetrate the water table shall be abandoned by completely filling with cement grout.
(Ord. passed 7-23-1984)
(A) Any person completing or abandoning any well in the county shall submit to the Health Department and to the well owner a record of the construction or abandonment to include: the owner’s name; the wells location, size, and depth; the casing record; the method of finishing or abandoning; formation log; static water level; pumping water level; yield; pump type; capacity and setting; and date of completion or abandonment.
(B) Any person repairing a well shall submit to the Health Department and the well owner a record of the repair to include: the owner’s name; location of the well; change in construction and materials replaced; and date of repair.
(C) The reports required in divisions (A) and (B) above shall be submitted to the Health Department within 30 days after completing construction, abandonment, or repair.
(D) Reports shall be certified by the contractor or persons completing the construction, abandonment, or repair.

(1) Figure No. 1 illustrates the proper seating and sealing of casing of wells constructed to obtain water from consolidated rock formations;
(2) Figure No. 2 illustrates the proper seating of screens required to prevent the entrance of formation material into a well constructed to obtain water from unconsolidated rock formations;
(3) Figure No. 3 illustrates the proper construction of gravel-packed wells;
(4) Figure No. 4 illustrates the construction of bored wells for domestic use;
(5) Figure No. 5 illustrates proper placement of required well identification plate, and the access port;
(6) Figure No. 6 illustrates proper placement of access ports;
(7) Figure No. 7 illustrates construction of an access port; and
(8) Figure No. 8 illustrates well chlorination required by § 52.56.
(B) Forms. The following forms required by these regulations are available upon request from the Health Department:
(1) Driller registration application;
(2) Certificate of registration;
(3) Completion or abandonment report; and
(4) Repair report.

Wells drilled in areas underlain by metavolcanic rocks identified on the 1958 State Geologic Map as bedded argillites of the Carolina Slate Belt shall be cased to a minimum depth of 35 feet. These areas are generally described as follows: a dominant landscape of gently sloping ridges and strongly sloping side slopes with well drained soils occurring on the uplands. The soils are characterized by deep soils with firm silty clay subsoils and soils with shallow rock and saprolite. The major soil series are Georgeville, Herndon, Tatum, Nason, Lignum, and Goldston.

(A) It shall be unlawful for any person or firm to rent or offer for rent, lease, or offer for lease, any residence or place of business without a potable water supply. The owner shall provide proof that the water quality meets bacteriological standards recommended by the Division of Health Services. The supply shall also have at least one sample recorded with the Health Department as to the nitrate level.
(B) All wells under this section shall be protected according to the recommended standards of the Division of Health Services.
(C) All supplies that serve two connections, residences or businesses, or more but less than 15 will be sampled by the Health Department for bacteriological analysis semi-annually.
(D) Where only one connection, residence or business, is involved, the Health Department shall be notified by the owner or agent upon occupancy of each new tenant. The Health Department will collect a sample for bacteriological analysis at that time.
(E) All water supplies covered under this section that fail to meet the bacteriological standards shall be treated by an approved chlorination method. If periodic contamination occurs, those water supply systems shall be equipped with mechanical devices to ensure adequate disinfection.
