, Groundwater is water stored below Earth's surface in soil, sediment, and rock.
Aquifers are underwater reservoirs that store ground water.
Good aquifers are usually porous and permeable materials such as gravel, sand, and sandstone, and some
fractured or dissolved rocks.
Aquitards store small amounts of water but do not transmit it well.
Aquicludes do not store significant water and do not transmit it, basically impossible to do so.
Clay, Shale and other non-porous rocks commonly act aquitards or aquicludes
as
Fractured rocks and karst limestone can transmit large amount of groundwater through cracks and conduits
Porosity amount of empty space that can hold fluids
Permeability Ability of rock or soil to allow water to flow through it
High porosity does not always mean high permeability
impermeable little to no fluid flow
water table the top of the saturated (water-filled) zone
Below water table, pores and fractures are filled with water
Groundwater flows from higher elevation or pressure toward lower elevation or pressure
Water table depth changes with season, climate, and location
Groundwater flow is perpendicular to water table contours
