The highest yielding aquifers are typically in unconsolidated sand and or gravel layers. Aquifers composed of highly porous sandstone or highly fractured rock can also make good aquifers. Contrary to popular belief most ground water is not found in underground lakes or streams.
An aquifer is a geologic formation (rock, gravel, or sand) that contains useable amounts of groundwater and can contribute that water to wells, springs, lakes, or streams. Groundwater is simply water in the ground, where it fills and moves through pores and cracks in the aquifer.
An aquifer is a body of saturated rock through which water can easily move. Aquifers must be both permeable and porous and include such rock types as sandstone, conglomerate, fractured limestone and unconsolidated sand and gravel. Fractured volcanic rocks such as columnar basalts also make good aquifers.
