permeable
Of a membrane, allowing a given substance to pass through.
Note: When applied to nonbiological membranes with no qualification, the term normally refers to water.
permeation
Action of entering or passing through a cell membrane.
Permeable layer: A layer of porous material (rock, soil, unconsolidated sediment); in an aquifer, the layer through which water freely passes as it moves through the ground.
permeable confining bed
permeameter
permeate To penetrate and pass through, as water penetrates and passes through soil and other porous materials.
Impermeable: Material that does not permit fluids to pass through.
Impervious: The quality or state of being impermeable; resisting penetration by water or plant roots.
Impermeable: Characteristic of geologic materials that limit their ability to transmit significant quantities of water under the head differences normally found in the subsurface environment.
Impermeable Not easily penetrated by water.
Impurities Particles or other objects that cause water to be unclear.
impermeable : Not easily penetrated, The property of a material or soil that does not allow, or allows only with great difficulty, the movement or passage of water.
in situ : In place, the original location, in the natural environment.
Semipermeable
A medium that allows water to pass through, but rejects dissolved solids, so that it can be used to separate solids from water.

impermeable Describes material or soil that does not allow, or allows only with great difficulty, the movement or passage of water. Compare permeable. imported water Water brought into an area from a distant source.
permeable surfaces that can replace asphalt and concrete and can be used for driveways, parking lots and walkways.
ANGLED Z LOT
A lot design where units are tilted at a 30 to 45 angle relative to the street.
Permeable Reaction Wall: Is similar to a cutoff wall, but the wall is relative to aquifer permeable so that groundwater flows through it unimpeded.
The impermeable layers in an aquifer.

A membrane, permeable to water and onliy very slightly permeable to gas when wet through which water can escape from a soil sample in response to a pressure gradient.

1. A relatively impermeable barrier designed to keep leachate inside a landfill. Liner materials include plastic and dense clay. 2. An insert or sleeve for sewer pipes to prevent leakage or infiltration.
Lipid Solubility ...
Deep-well Injection Deposition of raw or treated, filtered hazardous waste by pumping it into deep wells, where it is contained in the pores of permeable subsurface rock.
A highly permeable soil, such as sand, allows a liquid to pass through quickly. Clay has a low permeability. Persistence The quality of remaining for a long period of time (such as in the environment or the body).
Reverse osmosis: Mechanical pressure is applied to an impure solution to force pure water through a semi-permeable membrane.
Osmosis Diffusion of water across a semi-permeable membrane. Osmotic pressure The tendency of water to move across a semi-permeable membrane into a solution. Outbreeding In which genetically dissimilar organisms mate with each other.
CELL WATER RELATIONS - SELECTIVELY PERMEABLE MEMBRANES
So we now know that water moves in plants from high to low regions of water potential. Pure water has a water potential defined as zero.
Runoff is often considered to be the water flowing over either impermeable or saturated surfaces. This is the most common observed runoff and is called Horton Overland Runoff.
Water Table The level of ground water or the upper surface of the zone of saturation of groundwater above an impermeable layer of soil or rock (through which water cannot move) as in an unconfined aquifer.
That's because the plastic is permeable; the chemicals that cause a coin to tone can permeate through the plastic or along the slabs seals.
A process that uses electrical current applied to permeable membranes to remove minerals from water. Often used to desalinize salty or brackish water.

Hydraulic Conductivity: The rate at which water can move through a permeable medium. (i.e. the coefficient of permeability.)
Hydraulic Gradient: In general, the direction of groundwater flow due to changes in the depth of the water table.
Hydraulic Conductivity: The rate at which water can move through a permeable medium, i.e., the coefficient of permeability.
Hydraulic Gradient: In general, the direction of groundwater flow due to changes in the depth of the water table.
Groundwater: Water that sinks into the ground and collects over impermeable rock. It then flows laterally toward a stream, lake, or ocean. Wells tap it for our use. Its surface is called the Òwater tableÓ.
Confined aquifer. A water-bearing subsurface stratum that is bounded above and below by formations of impermeable, or relatively impermeable soil or rock.
Permeability - The property of permitting liquids or gases to pass through. A highly permeable soil, such as sand, allows a liquid to pass through quickly. Clay has a low permeability.
Reverse osmosis
a high pressure filtration system that uses selectively permeable membranes with extremely small pores to separate ions and particles ...
The passage of a liquid from a weak solution to a more concentrated solution across a semipermeable membrane that allows passage of the solvent (water) but not the dissolved solids.
Overdraft ...
A general term that encompasses all techniques for determining whether a subsurface geological formation may be sufficiently porous or permeable to serve as an aquifer.
Baghouse: An air pollution control device that traps particulates by forcing gas streams through large permeable bags usually made of glass fibers. For more information, please go tou our baghouse training website.
Osmoregulator: an organism that maintains a constant internal salt concentration Osmosis: the movement of water or other solvent across a semipermeable membrane from a region of low solute concentration to a region of high solute ...
An aquifer acts as a groundwater reservoir when the underlying rock is impermeable. This may be tapped by wells for domestic, agricultural or industrial use.
REVERSE OSMOSIS: A method of removing salts or other impurities from water by forcing water through a semi-permeable membrane.
Scientists use the term organic to mean those chemical compounds which are based on carbon. Permeability: The property of permitting liquids or gases to pass through. A highly permeable soil, such as sand, allows a liquid to pass through quickly.
