Leaking petroleum storage tanks from gas stations are one of the most common sources of contamination of groundwater in the U.S. and Texas. In 1992 a 2,900 gallon gasoline and diesel release occurred at the Big Wheel Truck Stop located on the highly sensitive Edwards Aquifer in Austin, Texas. The fate and transport of the…

Pleasant Valley Spring (PVS) and Jacob’s Well Spring (JWS) are large karst springs providing perennial baseflow to the Blanco River and Cypress Creek, respectively, which eventually recharges the Edwards Aquifer. JWS flow has become intermittent in recent years due to drought and increased pumping driven by nearby population growth within the Cypress Creek watershed. In…

The Blanco River of central Texas provides an important hydrologic link between surface and groundwater as it traverses two major karst aquifer systems—the Trinity and Edwards Aquifers. The Blanco River is characterized by alternating gaining and losing stretches due to the presence of springs that discharge water into the river and swallets that drain water…

This study refines the freshwater/saline-water interface in the Edwards Aquifer of Travis and Hays Counties based upon 855 data points compiled from measured or estimated total dissolved solids (TDS) in groundwater. Changes to the boundary include localized lateral shifts of up to 1.3 miles and an apparent net loss of 3.8 mi2 of areal extent…
