Aquifer-a ground water bearing stratum of permeable rock, sand, or gravel.
Area of Ground Water Concern-an area in which, under current usage and normal environmental conditions, sustainability of an aquifer is not being maintained due to either movement of a salt water front, water level decline, or subsidence, resulting in unacceptable environmental, economic, social, or health impacts, or causing a serious adverse impact to an aquifer, considering the areal and temporal extent of all such impacts.
Beneficial Use-the technologically feasible use of ground water for domestic, municipal, industrial, agricultural, recreational, or therapeutic purposes or any other advantageous purpose.
Commission-Ground Water Resources Commission authorized by R.S. 38:3097.4.

Ground Water Emergency-an unanticipated occurrence as a result of a natural force or a man-made act which causes a ground water source to become immediately unavailable for beneficial use for the foreseeable future or drought conditions determined by the commissioner to warrant the temporary use of drought relief wells to assure the sustained production of agricultural products in the state.
Large Volume Well-a well with an 8 inch or greater diameter screen size or a well that by itself or used in conjunction with another well or group of wells on the same lease or within the same unit and screened in the same aquifer for the purposes of providing ground water for hydraulic fracturing for natural gas production and that alone or in conjunction with the other well or wells is determined by the Office of Conservation to be capable of producing 1,500 gallons per minute.
Owner-the person registered as owner of a water well with the Office of Conservation, and if there is none registered for a specific well or proposed well then the owner shall be one of the following: the legal owner of the property on which the well or hole is located, a person holding a long-term lease on the property on which the well or hole is located, or a person who otherwise has the legal right to drill and operate a water well on the property of another where the well or hole is located.

Spacing-the distance a water well may be located in relation to an existing or proposed water well, regardless of property boundaries.
Sustainability-the development and use of ground water in a manner that can be maintained for the present and future time without causing unacceptable environmental, economic, social, or health consequences.
