Science of The Total Environment, 2016 Many karst regions are undergoing rapid population growth and expansion of urban land accompanied by increases in wastewater generation and changing patterns of nitrate (NO3(-)) loading to surface and groundwater. We investigate variability and sources of NO3(-) in a regional karst aquifer system, the Edwards aquifer of central Texas.

River Connectivity: A Comparative Review Between AI and Experts
Water Resources Research, Volume 61, Issue 11, November 2025.Abstract Rivers are critical corridors for the movement of energy, matter, and organisms and essential for maintaining ecological balance, economic activities, and recreation. This connectivity in rivers, describing the flow of mass and energy across multiple spatio‐temporal scales, is crucial for ecosystem resilience and function.

Uvalde Pool of the Edwards (Balcones Fault Zone) Aquifer [PDF]
, 2019 ABSTRACT The Uvalde Pool comprises the western portion of the San Antonio segment of the Edwards (Balcones Fault Zone) Aquifer. Assessment of available data on the hydrogeology of Uvalde County confirms the conceptualization that the Edwards Aquifer in Uvalde County to the west of the city of Knippa acts as a partially separate ...

The Edwards Aquifer: Earth's most diverse groundwater ecosystem?
International Journal of Speleology, 1981 Recent studies on the Edwards Aquifer, a karstic formed cavernous system in Texas, indicate an extremely diverse community of aquatic troglobites. Sampling of wells and springs is providing new insight into the dynamics of this fascinating system, which is possibly the most diverse subterranean aquatic ecosystem known in the world today.
