La. Admin. Code tit. 56 § V-125
A. For the purpose of the rules and regulations stated herein the following definitions shall apply.
Abandoned Well-a well whose use has been permanently discontinued or which is in such a state of disrepair that it cannot be used to supply water.
Active Well-an operating augered, dug, driven, bored, or drilled well that is used to supply water.
Aquifer Test-pumping tests are made in water wells for either one of two purposes or for both objectives;
a. to obtain information about the performance and efficiency of the well being pumped; or
b. to provide data from which the hydraulic characteristics of the aquifer can be calculated.
The test made to determine hydraulic characteristics is usually referred to as aquifer test.
Bacteriological Analysis-this analysis, usually for drinking water, generally consists of determining total coliform.
Biological Analysis-biological analysis of ground water is made only when there is a possibility of contamination from a surface source and an examination for microorganisms is made.
Board-the Board of Commissioners of the Capital Area Ground Water Conservation District.
Chemical Analysis-usually a report of dissolved minerals in the water and the water's physical properties, such as temperature. The minimum chemical properties that are usually determined are hardness, specific conductance, hydrogen-ion concentration (pH), dissolved solids, chloride, bicarbonate, iron, flouride and nitrate.
Commission-the Capital Area Ground Water Conservation Commission.
Contaminant-any physical, chemical, biological, or radiological substance or matter in water.
Contamination-any introduction into water of microorganisms, chemicals, wastes, or wastewater in a concentration that makes the water unfit for its intended use.
Department-the Louisiana Department of Public Works.
Detritus-unconsolidated sediment comprised of both inorganic and decaying organic material.
Director-the Director of Public Works of the State of Louisiana or his designated representative.
District-the Capital Area Ground Water Conservation District.
Drawdown-the difference, usually in feet, between the static (nonpumping) water level and the pumping level in a well for a stated period of pumping from the well.
Drill Cuttings-Samples of the material obtained during drilling which are the source of lithologic information needed for proper selection of screen openings. The principal objective of drilling test holes is to obtain samples.
Driller's Log-the driller's description of the geologic strata encountered, their thickness and depth.
Electrical Log-a record of the resistivities of the subsurface formations and the contained fluid and the spontaneous potentials generated in the borehole, both plotted in terms of depth below the land surface. Other similar logs made in boreholes are the induction logs. Other borehole geophysical logs that may be also available are the gamma ray, caliper and neutron. Usually only an induction or electrical log is available for new wells.
Inactive Well-a well which is not in operation but can be used, with a minimum of effort as an observation well or a supply well.
Lessee-see definition for water well owner.
Observation Well-a well used by the appropriate engineering or research group in studies of the water resources of an area.
Pollution-a condition created by harmful or objectionable material in water.
Potable Water-water whose bacteriological, physical, and chemical properties make it suitable for human consumption and other beneficial purposes.
Public Water System-a system for the provision to the public of piped water for human consumption, if such a system has at least 15 service connections or regularly serves at least 25 individuals.
Pumping Test-pumping tests are made in water wells for either one of two purposes or for both objectives:
a. to obtain information about the performance and efficiency of the well being pumped; or
b. to provide data from which the hydraulic characteristics of the aquifer can be calculated.
The test made to obtain information about the performance of the well is usually referred to as pumping test.
Pumping Water Level-the water level, usually expressed in feet, in a well that is being pumped, above or below a specific datum, usually land surface.
Registered Well-an inventoried well that has been assigned a local well number by the state and whose records are available.
Saline Water-water with a dissolved solids content of 1,000 milligrams per litre or more.
Seepage-the appearance and disappearance of water into the ground surface-a type of movement of water.
Specific Capacity-the rate of discharge of water from a well divided by the drawdown of water level within the well for a specified period of continuous pumping of the well. It is usually expressed as "gallons per minute per foot of drawdown after X hours of continuous pumping."
Standby Well-a well that is used in emergencies or occasionally as a replacement well for an active well.
Static Water Level-the water level usually expressed in feet, in a well that is not being pumped, above or below a specified datum, usually land surface.
State-State of Louisiana.
Test Hole-an augered, drilled, driven, or bored hole that is used for the collection of geologic, hydrologic, and water quality data.
Water Well Contractor-any person, organization, or corporation who engages for compensation in the drilling, boring, construction of a water well. Does not include anyone who drills, bores, cores, or constructs a water well on his own property for his own use.
Water Well Owner-an individual, corporation, association, partnership, institution, or governmental agency who is either the legal owner of the property on which the well is located or is holding a long term lease on the property (lessee).
