aquitard
An impermeable layer along an aquifer
The less permeable beds in a stratigraphic sequence; beds may be permeable enough to transmit water in quantities that are significant in the study of regional groundwater flow or environmental contamination, but their permeability is not sufficient to allow completion of production wells within them
layers of rock with low permeability
A geologic unit that inhibits the flow of water
A part of a geologic formation (or one or more geologic formations) that is of much lower permeability than an aquifer and will not transmit water at a rate sufficient to feed a spring or for economic extraction by a well
A body of rock or sediment that retards but does not prevent the flow of water to or from an adjacent aquifer It does not readily yield water to wells or springs but may serve as a storage unit for groundwater GG
A layer of rock having low permeability that stores groundwater but delays its flow
A unit that retards or slows the passage of water
– An underground formation that is impermeable to or impedes the movement of water
A saturated, relatively lower permeability geologic unit within a stratigraphic sequence relative to the aquifer of interest (This terminology is used much more frequently in practice than aquiclude, in recognition of the rarity of natural aquicludes )
Slowly permeable stratum that retards water movement into and out of adjacent or underlying aquifers
A water-saturated sediment or rock whose permeability is so low it cannot transmit any useful amount of water
A geologic formation that is not permeable enough to yield significant quantities of water to wells, but on a regional scale can contribute significant water to the underlying or overlaying aquifers
Geological formations or strata that have the ability to store water but can only transmit water in very small quantities (eg silt, siltstone)
underground geological formation that is slightly permeable and yields inappreciable amounts of water when compared to an aquifer List of Glossary Terms
A geological formation that will not transmit water quickly enough to fill a well,practically, but may store some quantities of water
A rock unit or layer or layer that stores water and allows it to move only at a very slow rate
