Ecophysiology and Food Web Dynamics of Spring Ecotone Communities in the Edwards Aquifer, USA
Spring orifices serve as ecotones between groundwater and surface water habitats. It is thought that organisms living in physicochemically stable spring ecotones should exhibit small tolerance ranges; however, previous experiments examining this prediction are equivocal. I examined this hypothesis …

Water From a Stone: The Limits of the Sustainable Development of the Texas Edwards Aquifer
… the limits on the sustainable development of the Edwards (Balcones Fault Zone) Aquifer in south central Texas as the minimum discharges from Comal Springs in New Braunfels, Texas, and San Marcos Springs, in San Marcos, Texas. This conflict is aggravated by periodic droughts that increase the …

Geologic and Geochemical Characterization of Cross-Communication Potential within the Northern Edwards Aquifer System, Texas
<p>The Edwards Aquifer is a large, complex groundwater system located throughout Central Texas in association with the Balcones Fault Zone. The San Antonio and Barton Spring segments of the Edwards Aquifer have been extensively studied in the past because they provide groundwater resources to the …

Texas State University's San Marcos Campus Edwards Aquifer Groundwater Use Trends and Untapped Water Conservation Opportunities
… The TXST San Marcos campus relies on the Edwards Aquifer, an environmentally sensitive and economically important water resource, for ~70% of their potable water supply and Spring Lake and the San Marcos River for non-potable water uses. The Edwards Aquifer provides water to over 2 million …

Speleogenesis of Critchfield Bat Caves and Associated Hydrogeology of the Northern Edwards Aquifer, Williamson County, Texas
<h1> </h1> <p>Karst development in the Edwards Aquifer has been significantly studied in the San Antonio and Barton Spring Segments; however, karst development remains poorly studied in the Northern Segment. Detailed characterization of the Northern Segment is vital for future water conservation …

Assessment and Conceptualization of Groundwater Flow in the Edwards Aquifer Through the Knippa Gap in Uvalde County, Texas
<p>The Edwards aquifer is one of the major regional karst aquifers in the United States, with an average withdrawal of 950 million liters per day (L/d). This investigation focuses on the connection between the Uvalde pool and the San Antonio pool of the Edwards aquifer, known as the Knippa Gap, …

Hydrogeology and stream interactions of the Edwards Aquifer in the Salado Creek Basin, Bell and Williamson Counties, Central Texas.
The northern extent of the Balcones Fault Zone Edwards aquifer discharges through more than 20 perennial springs into the lower reaches of the Salado Creek. In the upper reaches, Salado Creek is a losing stream and groundwater recharge occurs through the stream channel. The Balcones Fault Zone …

The Protracted Dispute over the Edwards Aquifer: Revisiting and Reframing Multiparty Stakeholder Conflicts in Management, Regulation, Allocation, and Property Rights
… and San Antonio and the Hill Country where the Edwards Aquifer is located. Extreme population growth increases stress on existing natural resources and will require dramatic improvements in water conservation and reuse, as well as preservation of land held in conservation to protect water …

Macro and Micro Litter Accumulation in the San Marcos River San Marcos, Texas, USA
… San Marcos River is primarily spring-fed by the Edwards Aquifer and provides habitat to seven federally-listed species, some of which are only found within the first few kilometers of the main stem. Thousands of tourists recreate on the San Marcos River during the late spring and summer, and …

Groundwater Hydrogeolgy and Hydrochemistry of Karst Springs in the Eastern Peninsula of Fort Hood Military Installation
… segment of the northern section of the Edwards Aquifer. This study utilized standard ion index values, repeated measures, and principal component analyses on the chemical profiles of six perennial springs to classify spring water sources and their chemical composition. Spring water …

The springshed and potential recharge areas for the Downtown Salado Spring Complex, Salado, Texas.
The Northern Segment of the Edwards (BFZ) Aquifer is a complex, karst system experiencing increases in groundwater demand and environmental stresses in response to a growing population. This study delineated the Salado Springshed under baseflow conditions and identified significant recharge zones …
