Montmorillonitic clay, as indicated by the shrink-swell potential of this site, is able to retain cations more effectively than non shrinking clays such as kaolinite.
Saprolite- A soft, clay-rich, thoroughly decomposed rock formed in place by chemical weathering of igneous or metamorphic rock. Forms in humid, tropical, or subtropical climates.
Earthflow:a landslide that consists of material that is moist and full of clay, yet drier than the material in mudflows.
Alluvium - material, such as sand, silt, or clay, deposited on land by streams.
Basin - a low area with no surface water outlet.
Clay has a low permeability. Persistence The quality of remaining for a long period of time (such as in the environment or the body). Persistent chemicals (such as DDT and PCBs) are not easily broken down.

A group of fibrous, inorganic materials that contain aluminum or calcium silicates, and are made from rock or stone, clay, slag, or glass. Synthetic vitreous fibers are widely used for thermal and sound insulating.
cap : A fairly impermeable seal, usually composed of clay-type soil or a combination of clay soil and synthetic liner, which is placed over a landfill during closure.
Alluvial Deposits: The general name for all sediments, including clay, (Alluvium) silt, sand, gravel or similar unconsolidated material deposited in a sorted or semi-sorted condition by a stream or other body of running water, in a stream bed, ...
bentonite A colloidal clay, largely made up of the mineral sodium montmorillonite, a hydrated aluminum silicate. Because of its expansive property, bentonite is commonly used to provide a tight seal around a well casing.
Alluvium. A stratified bed of sand, gravel, silt, and clay deposited by flowing water.
AMP. Allen McColloch pipeline, operated by the Metropolitan Water District of Southern California to transport imported water within Orange County.
Bentonite: highly plastic clay consisting of the minerals montmorillonite and beidellite that swells when wet and is often used as a lining material to seal landfills and lagoons.
Seal: The impermeable material, such as cement grout bentonite, or puddling clay placed in the annular space between the borehole wall and the casing of a water well to prevent the downhole movement of surface water or the vertical mixing of ...

Bentonite- A colloidal clay, expansible when moist, commonly used to provide a tight seal around a well casing.
Confined aquifer: (also known as artesian or pressure aquifers) exist where the groundwater is bounded between layers of impermeable substances like clay or dense rock.
aquifer: Aquifers are places underground through which water flows, like sand, gravel, or even clay. People drill wells hoping to hit an aquifer for a good course of water.
Natural sources include salt particles from sea spray and clay particles as a result of weathering of rocks, both of which are carried upward by the wind. Aerosols from human activities are often considered pollutants.
Pica
A craving to eat nonfood items, such as dirt, paint chips, and clay. Some children exhibit pica-related behavior.
Perched Aquifer: An aquifer containing unconfined (unpressurized) groundwater held above a lower body of groundwater by an unsaturated zone; often a result of clay lenses in the soil strata. DIAGRAM ...
LINER Barrier designed to prevent the leaching of contents from a landfill. Commonly comprised of plastic or dense clay.
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.

trees more susceptible to frost, fungi, and insects. Root growth slows and as a result less nutrients are taken up. Toxic ions are mobilized in the soil, and valuable minerals are leached away or (as in the case of phosphate) become bound to clay.
Alfisols An order of soils with a medium-to-high base supply, horizons of clay accumulation, and gray-brown surface horizons.
