Louisiana Administrative Code › Title 56 - PUBLIC WORKS › Part V - Capital Area Ground Water Conservation Commission › Chapter 1 - Water Well Registration in the Capital Area Ground Water Conservation District › Section V-125 - Definitions

Current through Register Vol. 50, No. 6, June 20, 2024
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).
AUTHORITY NOTE:
				  Promulgated in accordance with
				  R.S.
				  38:3076(14) and
				  38:3079.
