Aquifers are defined in the Meriam-Webster Dictionary as “a water-bearing stratum of permeable rock, sand, or gravel.”. As the definition says, an aquifer is a water bearing stratum. In the following picture from USGS, the aquifer is anything below the water table. This image shows where the aquifer is located.aquifer--a geologic formation(s) that is water bearing. A geological formation or structure that stores and/or transmits water, such as to wells and springs. Use of the term is usually restricted to those water-bearing formations capable of yielding water in sufficient quantity to constitute a usable supply for people's uses.An aquifer according to word web dictionary refers to any underground layer of water-bearing rock or geological formation that yields sufficiently groundwater for wells and springs.
