Aquitard definition
Aquitard or “Confining Layer” means a layer of low permeability material, such as clay or rock, adjacent to an aquifer that functions to prevent the transmission of significant quantities of groundwater flow under normal hydraulic gradients.
Aquitard means a geological formation or stratum, or artificial barrier, of relatively low permeability which will not transmit water fast enough to furnish an appreciable supply; confining zone.
Aquitard means a hydrogeologic confining unit(s) that exhibits limited permeability, bounding one or more aquifers, that does not readily yield water to wells or springs, but may serve as a storage unit for ground water and may release this water to adjacent ground water units or
Examples of Aquitard in a sentence
There are four important subclasses of Hydrogeological Unit: Aquifer, Aquitard, Aquiclude and Aquifer System • An Aquifer is a wet underground layer of water-bearing permeable rock or uncon- solidated materials (gravel, sand, silt, or clay) from which groundwater can be use- fully extracted by a groundwater well.

More Definitions of Aquitard
Aquitard means a saturated but poorly permeable bed, formation, or group of formations that does not yield water freely to a well or a spring. An aquitard retards, but does not prevent, the flow of water to or from an adjacent aquifer.
Aquitard means a saturated but poorly permeable bed, formation, or group of formations that does not yield water freely to a well or a spring. An aquitard may transmit appreciable water to or from adjacent aquifers.
Aquitard means an underground geologic layer that has low permeability.
Aquitard. – means a rock or clay layer that is not permeable enough to yield usable quantities of water to a well or springs under ordinary hydraulic gradients.
Aquitard means a hydrogeologic confining unit(s) that exhibits limited permeability, bounding one or more aquifers, that does not readily yield water to wells or springs, but may serve as a storage unit for ground water and may release this water to adjacent ground water units or surface waters. Such confining units are further defined and listed in N.J.A.C. 7:9C- 1.5(f)1 or may be established through reclassification under N.J.A.C. 7:9C-1.10.
