Groundwater Awareness


Groundwater is water located beneath the earth surface. Precipitation that falls on the Earth’s surface moves down to fill voids in the soil and rock matrix.  A unit of rock or unconsolidated deposit is called an aquifer when it can yield a sustainable quantity of water.  

Groundwater is used extensively throughout Kentucky for domestic, agricultural, commercial and industrial purposes.  Because of its connection with streams and rivers, lakes and wetlands, groundwater is essential to the health of surface water ecosystems.  Groundwater is the source of drinking water for close to 2 million Kentuckians.

Understanding and protecting groundwater are of paramount importance to the commonwealth and its citizens.
