Section 118-4-003

Universal Citation: 118 NE Admin Rules and Regs ch 4 ยง 003

Current through March 20, 2024

All ground waters of the State are classified into one of the following classes:

003.01 Class GA. Ground water currently being used as a public drinking water supply or is proposed to be used as a public drinking water supply is assigned to Class GA. This includes:

003.01A Ground water withdrawn by a public water supply system that is used or is intended to be used as drinking water. This includes wells used incidentally or intermittently for drinking water and wells that are temporarily not being used (but have been used in the past) for drinking water. Class GA is determined by delineating a boundary around:
003.01A1. An area, based on local hydrogeologic conditions around a well or wellfield, defined by the Department, or the local water system involved (as approved by the Department ), including wellhead protection areas, as defined by the Department through the Nebraska Wellhead Protection Program.

003.01A2. An area at least as large as and encompassing the entirety of that described by 003.01A3. below designated through local ordinances, if 003.01A1. above has not been determined; or

003.01A3. The area within a 1,000-foot radius of a single well or the area within a 1,000-foot distance of the perimeter of a wellfield, if neither 003.01A1. nor 003.01A2. above has been determined.

003.01B Ground water represented by an area of overlying land which has been zoned or purchased by a local government for the purpose of developing a public drinking water supply well or wellfield, including ground water in provisional wellhead protection areas as defined by the Department through the Nebraska Wellhead Protection Program.

003.02 Class GB. Ground water currently being used as a private drinking water supply or has the potential for being used as a public or private drinking water supply but currently not classified as GA is assigned to Class GB. Class GB is assigned to all ground waters in the State except those assigned to Classes GA and GC.

003.03 Class GC. As of the effective date of these regulations, Class GC has not been assigned to any ground waters in the State. Ground water assigned to this class is not being used, and has little or no potential for use, as a public or private drinking water supply. Class GC is assigned on a case-by-case basis when information becomes available and will include, but not be limited to:

003.03A Ground water with poor natural or background quality compared to the numerical standards of Chapter 3. Class GC(R), a subset of Class GC, will be assigned to certain portions of this ground water if the Department determines that restoration or cleanup may be appropriate, pursuant to the provisions of Chapter 6, to allow for attainment of future beneficial uses.

003.03B Ground water in which hydrogeologic conditions make development of a public or private drinking water supply unlikely. Such information as depth to ground water and the transmissivity and areal extent of the aquifer may be considered.
