(a) Location.

1. (1) Every ground water supply such as a well or infiltration system and appurtenances thereto must be located:

   1. (A) On a site having good surface drainage, at a higher elevation than, and at a safe distance from any barnyard, privy, cesspool, soil pipe, any pipe through which sewage may back up or overflow or from any other possible source of pollution; and
   2. (B) In such a manner as to prevent the contamination of the water by either the:

(i) Underground seepage or channels;

1. (ii) Lakes; or

   1. (iii) Surface drainage.

2. (2)

   1. (A) The horizontal distance from and possible source of contamination such as privies, septic tanks, subsurface pits, seepage pits, subsurface sewage disposal fields, and barnyards shall be no less than one hundred feet (100’).
   2. (B) This distance shall be used only where conditions indicate them to be safe, and greater distances shall be required where local conditions necessitate.
3. (3) No well head, well casing, or well pump shall be located in any pit, room, or space extending below ground directly over the well.

(b) Protection.

1. (1) Wells.

   1. (A) Every well must have a durable, watertight casing extending a sufficient depth to exclude subsurface contamination, as determined by the Department of Health.
   2. (B) In no case shall the casing terminate less than ten feet (10’) below the ground surface, or deeper as dictated by the department.

   3. (C) Every well must be protected at the surface by a watertight slab or platform:

      1. (i) Extending a minimum of two feet (2’) in all directions from the well; and
      2. (ii) Sloped to provide drainage away from the well.
   4. (D) The casing or curb should extend at least six inches (6”) above the graded-up land surface at the well.
   5. (E) The annular space between the excavation line and the casing or curb should be grouted with cement.
   6. (F) The use of pitless adapters is prohibited.

2. (2) Well cover and seals.

   1. (A) Every well must be provided with an overlapping, water-tight cover at the top of the casing or pipe sleeve to prevent contaminated water or other deleterious material from entering through the opening at the top of the well casing or pipe sleeve.
   2. (B) Every cover, pump, platform, or pump room floor must be watertight and elevated above the adjacent land area.

3. (3) Pumps.

   1. (A) Pumps must be of suitable design so as to exclude contamination from the water chamber of the pump head.

   2. (B) Use of a bucket lift or ordinary lift pump with a slotted top which is open to contamination or requires priming is prohibited.

      1. (c) Maintenance. No owner or occupant of any establishment or premises shall maintain any well, spring, or other source of water used for drinking and domestic purposes:
4. (1) To which the public has or may have access; and

5. (2) Which is polluted or so situated or constructed that in any manner that may cause such water to be detrimental to public health.

   1. (d) Restricted wellhead protection zone.
6. (1) The owners of water supplies utilizing a well source shall effectively control a restricted wellhead protection zone around the well at a minimum of one hundred feet (100’) in radius.
7. (2) Deviation may be approved by the department on a case­by-case basis, provided it can be shown through scientific data that the ground water can be protected.
