An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground.

Aquifer characterization is analogous to reservoir characterization in the oil and gas industry, whose goal is to describe the spatial distribution of petrophysical properties (e.g., permeability and porosity) in three-dimensional space (Lucia 1995).

An aquifer is filled with moving water and the amount of water in storage in the aquifer can vary from season to season and year to year. Ground water may flow through an aquifer at a rate of 50 feet per year or 50 inches per century, depending on the permeability. But no matter how fast or slow, water will eventually discharge or leave an ...
