Basic Groundwater Principles

Hydrogeology

Hydrology is the science of water occurrence, movement and transport. Hydrogeology is the part of hydrology that deals with the occurrence, movement and quality of water beneath the earth's surface.

Water is continually moving within and above the earth in a cycle known as the hydrologic cycle or water cycle. This cycle ensures continual recycling of water throughout the environment by receiving energy from the sun. There are six major components of this cycle:

How the hydrologic cycle relates to groundwater and your well

The hydrologic cycle consists of:

It is the continuous recharging of the aquifer that allows your well to receive a sufficient supply of water.
