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.  In this session we’ll discuss aquifer types, Comal County water table levels, the hill country’s two general types of aquifers: confined and unconfined, common misconceptions about aquifers, rates at which groundwater moves through an aquifer, aquifer depletion and replenishment rates, as well as the natural filtration process of the earth.

Water Conservation Series

This session is part of the Water Conservation Series. These workshops were developed in response to common questions and concerns about various topics related to water conservation, water quality, pollution increases, and ecological issues.  The workshops provide a brief overview (with a chance for questions and answers) for Texas Hill Country residents to better understand where our water comes from and how to protect this important resource. The 10 sessions in this weekly series take place on Mondays from 12:00pm to 1:30pm beginning June 5th and ending August 7th. Feel free to bring your lunch while you learn of ways we all can protect our precious water sources!
