Intergranular Aquifer

In unconsolidated sediments (silts, sands and gravels) groundwater is stored in the pore spaces between loose grains of sediment.

These aquifers can often provide very reliable supplies where there is a reasonable thickness of saturated sediment present. In some places, the aquifer may be perched above a clay layer which is not extensive enough to provide enough storage for a good supply.
