| (H) a closed system geothermal well used to circulate
water, other fluids, or gases through the earth as a heat source or
heat sink.
(33) Injurious water--Water that is harmful to vegetation,
land or other water as set forth in §1901.254(a) and §1902.252(a)
of the Code.
(34) Irrigation distribution system--A device or combination
of devices having a hose, pipe, or other conduit which connects directly
to any water well or reservoir connected to the well, through which
water or a mixture of water and chemicals is drawn and applied to
land. The term does not include any hand held hose sprayer or other
similar device, which is constructed so that an interruption in water
flow automatically prevents any backflow to the water source.
(35) Monitoring well--An artificial excavation that
is constructed to measure or monitor the quantity or movement of substances
below the surface of the ground, and that is not used in conjunction
with the production of oil, gas, or other minerals.
(36) Mud for drilling--A relatively homogenous, viscous
fluid produced by the suspension of clay-size particles in water or
the additives of bentonite or polymers.
(37) Offering to act--Making a written or oral proposal,
contracting in writing or orally to perform well drilling or pump
installing work, or advertising in any form through any medium that
a person or business entity is a well driller or pump installer, or
that implies in any way that a person or business entity is available
to contract for, act as a driller or installer, or perform well drilling
or pump installing work.
(38) Piezometer--A device so constructed and sealed
as to measure hydraulic head at a point in the subsurface.
(39) Piezometer well--A well of a temporary nature
constructed to monitor well standards for the purpose of measuring
water levels or used for the installation of piezometer resulting
in the determination of locations and depths of permanent monitor
wells.
(40) Placement and preparation for operation of equipment
and materials--Includes but is not limited to removing the pump.
(41) Plugging--An absolute sealing of the well bore.
(42) Pollution--The alteration of the physical, thermal,
chemical, or biological quality of, or the contamination of, any water
that renders the water harmful, detrimental, or injurious to humans,
animals, vegetation, or property, or to public health, safety, or
welfare, or impairs the usefulness or the public enjoyment of the
water for any or reasonable purpose.
(43) Positive Displacement method--The process in which
the cement, bentonite or a combination of the two sealing materials
is forced through the well casing followed by water or drilling fluids,
via a mechanical pump and out through relief holes in the casing at
the maximum depth of the zone to be grouted. The grout then returns
under pressure to the surface through the annular space and upon curing
or setting causing an annular seal.
(44) Potable water--Water which is safe for human consumption
in that it is free from impurities in amounts sufficient to cause
disease or harmful physiological effects.
(45) Public water system--A system supplying water
to a number of connections or individuals, as defined by current rules
and regulations of the Texas Commission on Environmental Quality,
30 TAC Chapter 290.
(46) Recharge zone--Generally, that area where the
stratigraphic units constituting the Edward Aquifer crop out, including
the outcrops of other geologic formations in proximity to the Edwards
Aquifer, where caves, sinkholes, faults, fractures, or other permeable
features would create a potential for recharge of surface waters into
the Edwards Aquifer. The recharge zone is identified as that area
designated as such in official maps in the appropriate regional office
of the Texas Commission on Environmental Quality.
(47) Reconditioning--The process where a well is cleaned
out to original depth and the water production is restored. This term
shall include any procedures that make the well operable.
(48) Re-completion--The process to bring an existing
well into compliance with §76.100 or §76.105 by installing
any and all sanitary seals, safeguards, casing, grouting, and the
re-setting of well screens as required.
(49) Recovery well--A well constructed for the purpose
of recovering injurious groundwater for treatment or removal of contamination.
(50) Sanitary well seal--A watertight device to maintain
a junction between the casing and the pump column.
(51) Test well--A well drilled to explore for groundwater.
(52) Tremie pipe method--The process in which a small
diameter pipe or tubing is inserted in the annular space of the well
to the maximum depth of the zone to be sealed, before the grouting
procedure is commenced to pump sealing material through. The tubing
or pipe may be retrieved during the grouting process, causing an annular
seal.
(53) Water or waters in the state--Groundwater, percolating
or otherwise, lakes, bays, ponds, impounding reservoirs, springs,
rivers, streams, creeks, estuaries, marshes, inlets, canals, the Gulf
of Mexico inside the territorial limits of the state, and all other
bodies of surface water, natural or artificial, inland or coastal,
fresh or salt, navigable or non-navigable, and including the beds
and banks of all watercourses and bodies of surface water, that are
wholly or partially inside or bordering the state or inside the jurisdiction
of the state.
(54) State of Texas Well Report (Well Log)--A log recorded
on forms prescribed by the department, at the time of drilling showing
the depth, thickness, character of the different strata penetrated,
location of water-bearing strata, depth, size, and character of casing
installed, together with any other data or information required by
the executive director.
