Current through June 17, 2024
These requirements apply to all water wells constructed under
				  Title 178 NAC 12, except as modified in 178 NAC 12-004 through 12-014.
12-003.01
Protection and
				Location
:
12-003.01A A well must
				not be located in a well pit.
12-003.01B
Protection:
All water wells must be protected from
				surface drainage, flooding and seepage from sources of contamination and
				pollution by:
1. Locating the well site to
				promote drainage away from the well, and
2. Terminating the top of the well and vent
				above the 100 year flood plain, or
3. Locating on a berm and/or within a dike to
				protect the well from a 100 year flood, or
4. Plugging the vent and seal at the top of
				the well if yield is less than 50 GPM.
12-003.01C
Separation
				distances
must at a minimum comply with the distances listed in
				Chart 1 (or Chart 2 if the requirements in 178 NAC 12-003.01C item 2 are met).
				Be aware that other state, NRD, and local statutes and regulations may have
				more restrictive requirements. If locations are found to not comply with more
				stringent standards of other state or local regulations that apply, the
				Department may notify the appropriate authority.
1. All water wells except those covered in
				178 NAC 12-007 must meet the minimum separation distances in accordance with
				Chart 1 below.

2. A

a. Compliance with the separation distances
				established in Chart 1 cannot be met; and
b. The well driller notifies the Department
				in writing of his/her intent and receives Department written approval prior to
				construction; and
c. The water well
				is grouted the full length of the annular space from immediately above the
				gravel pack above the screened openings to the surface with chip bentonite; and
d. The subsurface geology includes
				sufficient silts and/or clays that will provide a protective seal to the
				groundwater when combined with chip bentonite.

				proposal is substantially equivalent to the regulations.
