Central Texas’ groundwater, karst landscape, and innovative residents are fascinating! Local researchers, agencies, and organizations (the Aquifer District included) have made a lot of the science accessible through videos, activities & experiments, and resource pages. Here’s a list by category.
- Well Construction: A properly constructed well can provide clean, safe water for years. Well construction standards help protect water quality and extend the service life of the well. A poorly constructed well can have poor water quality and/or limited access to groundwater over time.
- What Is Dye Tracing and How Is It Used in Groundwater Research?: Groundwater dye traces use non-toxic dye to determine flow paths in aquifers. In the Barton Springs segment of the Edwards Aquifer, dye traces have shown that water can travel as fast as 17 miles in 3 days.
- Recharge: Karst recharge features like caves, swallets, and faults in creek beds replenish aquifers by allowing surface water into the groundwater system. Features vary in size and volume of water they can channel into the groundwater system.
- Antioch Cave and Recharge Enhancement: Antioch Cave is a large karst feature in Onion Creek that supplies a substantial amount of recharge to the Barton Springs segment of the Edwards Aquifer. In order to protect and enhance recharge to the aquifer, the District constructed a Recharge Enhancement Vault over Antioch Cave.
- Springs: Springs and artesian wells are indicators of the overall health of an aquifer. Healthy springs indicate healthy aquifers. Artesian flowing wells and increased springflow indicate high groundwater levels. Springs help sustain the flow in area creeks and rivers.
- Blanco River Springs: Springs provide important base flow for the Blanco River. Hill Country Trinity Aquifer springs flow even when it’s not raining. As the Blanco flows downstream, it eventually passes over the Edwards Aquifer Recharge Zone and helps replenish the Edwards Aquifer.
