National Groundwater Awareness Week is March 7–13. This week promotes greater awareness for groundwater and how we can each do our part to protect this valuable resource. Groundwater provides a large percentage of the water supplies in Texas, so it is important to recognize this significant resource and learn how each Texan can do their part to protect our groundwater supply.

The Basics of Groundwater

Groundwater is found in layers of sand and rock called aquifers. Aquifers typically consist of gravel, sand, sandstone, or fractured rock like limestone or granite. These permeable materials have connected spaces that allow water to flow through. The speed at which the groundwater flows depends on the size of these spaces in the soil or rock and how well the spaces are connected. The groundwater supply is replenished by rain, snow melt, or runoff moving through the overlying layers of soil and seeping into the aquifer below.

Although groundwater is out of sight, it is a very important resource. In Texas, groundwater provides 62 percent of all freshwater that is used and supplies 75 percent of the water that is used for agriculture. Also, groundwater is a source of drinking water for more than 11 million Texans.
