The Secret Life of Groundwater

About this presentation

Texas Water Development Board

Humans’ understanding and connection to groundwater is a complicated relationship. Humans have historically relied on groundwater to supply their water needs. In fact, more water used in Texas is supplied by groundwater than surface water. Yet groundwater does not stay within manmade boundaries such as city, county, state, or even country borders. This makes regulating groundwater difficult. It also makes being able to use and protect this hidden resource more dependent on understanding the formation and characteristics of aquifers. In this session you’ll learn about what an aquifer is, how water is stored in and moves through an aquifer, and how what we do as humans can impact our groundwater resources.
