Controls on the regional-scale salinization of the Ogallala aquifer, Southern High Plains, Texas, USA
An extensive saline plume (>250 km) within the regionally important uncon®ned aquifer in the Neogene Ogallala Formation overlies the Panhandle oil and gas ®eld in the Southern High Plains, Texas, USA. Relative to upgradient Ogallala water, the plume waters have dO (ÿ6.7 to ÿ8.8-) and dD (ÿ42 to ÿ88-) values that tend to be depleted and have higher Cl (>150 mg/l) and SO4 (>75 mg/l) concentration...
متن کاملIntegrating Cotton and Beef Production to Reduce Water Withdrawal from the Ogallala Aquifer in the Southern High Plains
planted annually, primarily in monoculture systems (TASS, 2002). Furthermore, about 5.5 million stocker Agriculture in the Texas High Plains depends heavily on irrigation cattle (about 25% of U.S. total; TASS, 2002; USDA with water withdrawn from the Ogallala aquifer at nonsustainable rates. Our hypothesis was that integrating crop and livestock systems Natl. Agric. Stat. Serv., 2003) are shipp...
متن کاملAssessing the Option Value of the Ogallala Aquifer in Texas High Plains: a Contingent Valuation Approach
The decline of the groundwater in the Ogallala Aquifer may create an uncertainty for water availability in the associated states in the future. Effective policy reforms are essential to determine efficient present and future use of water resources. Therefore, this study explores the option value for reducing current groundwater use to ensure the water availability in the Ogallala aquifer for fu...
متن کاملTrends in Playa Inundation and Water Storage in the Ogallala Aquifer on the Texas High Plains
The Ogallala Aquifer is an important source of irrigation water on the Texas High plains; however, significant decreases in saturated thickness threaten its future use for irrigation. A better understanding of the roles of playas, ephemeral surface ponds, in aquifer recharge is needed to establish levels of withdrawals that will meet either established desired future conditions or sustainabilit...
متن کاملElevated naturally occurring arsenic in a semiarid oxidizing system, Southern High Plains aquifer, Texas, USA
High groundwater As concentrations in oxidizing systems are generally associated with As adsorption onto hydrous metal (Al, Fe or Mn) oxides and mobilization with increased pH. The objective of this study was to evaluate the distribution, sources and mobilization mechanisms of As in the Southern High Plains (SHP) aquifer, Texas, relative to those in other semiarid, oxidizing systems. Elevated g...
