        Officials with the Uvalde County Underground Water Conservation District said the legal action was taken partly in response to the San Antonio-based Edwards Aquifer Authority’s rules revisions.   As Texas reopens public pools, San Antonio says it will wait. A trip into the Edwards Aquifer. By Colin McDonald. Updated pm CDT, Thursday, J Author: Colin Mcdonald.

      The Edwards aquifer of central Texas is an extensive, karstified flow system developed in rocks deposited on a Cretaceous limestone platform. Development of this prolific aquifer was controlled by changes in sea level, large-scale hydrodynamic and tectonic processes in the Gulf of Mexico, and local climatic and geomorphic processes. Two-thirds of all Edwards Aquifer recharge occurs west of San Antonio. The remaining one-third enters through updip, unconfined parts of the aquifer in Bexar, Comal, and Hays counties. Reference: Blome, C.D., J.R. Faith, and G.B. Ozuna, , Geohydrologic framework of the Edwards and Trinity aquifers, south-central Texas: U.S. Geological.

      IMPORTANT NOTE: A more recent version of this data release is available from this link. The Edwards aquifer in south central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to .   The Edwards Aquifer now is low enough — and dropping fast enough — to surpass the record low by this summer, projections from the San Antonio Water System show. It's a worst-case : Colin Mcdonald.

The Edwards Aquifer is a home to diverse fauna and is a drinking water source for the city of San Antonio and. The Edwards Aquifer is one of the most prolific artesian aquifers in the world.

Located on the eastern edge of the Edwards Plateau in the U.S. state of Texas, it is the source of drinking water for two million people, and is the primary water supply for agriculture and industry in the aquifer's addition, the Edwards Aquifer feeds the Comal and San Marcos springs, provides Geology: Limestone karst.

The Edwards (Balcones Fault Zone) Aquifer in the San Antonio, Texas, area was the first to be designated a sole source aquifer by the Environmental Protection Agency in The Edwards Aquifer also hosts unique groundwater, cave, and spring ecosystems.

Sincethe U.S. Geological Survey, in cooperation with the San Antonio City Water Board and the Texas Department of Water Resources, has collected geo­ logical, geophysical, hydrologic, and hydrochemical data of the Edwards aquifer in the San Antonio area and has prepared data and interpretative by: 4.

The Edwards Aquifer is one of the most valuable water resources in the central Texas area. This aquifer provides water for municipal, industrial, and agricultural uses. A number of cities rely on the aquifer as their only source of drinking water.

In the past, the Aquifer has proved to be a reliable source of water through severe droughts. FRESHWATER ZONE/SALINEWATER ZONE INTERFACE IN THE EDWARDS AQUIFER, SAN ANTONIO REGION, TEXAS By Dianne Pavlicek, Ted A. Small, and Paul L.

Maclay and T. Small U.S. Geological Survey INTRODUCTION Purpose and Scope of This Report The Edwards Limestone contains one of the most highly permeable and productive aquifers in Texas, and a knowledge of the nature of its pore system is useful for interpretations of the. Celebration of San Antonio River flow augmentation discharge: SAWS' project also involved augmenting the flow of the San Antonio River in the downtown area with recycled water so that Edwards wells supplying flow to the River Walk could be shut off.

The first discharge of recycled water occurred on Manear the inlet to the river flood tunnel, and it marked a. Regional differences in the porosity and permeability of the Edwards aquiifer are related to three major depositional areas, the Maverick basin the Devils River trend, and the San Marcos platform, that existed during Early Cretaceous time.

The rocks of the Maverick basin are predominantly deep basinal deposits of dense, homogeneous mudstones of low primary porosity.

Issues Surrounding the Edwards Aquifer. A Brief Retrospective and a Summary. I am always surprised at how little and how slowly this page has to be changed. When I started this website inthe primary issue that had to be resolved was how much users could pump, and the Edwards Aquifer Authority had been handed the job of allocating water.
