Paper presents changes in Ogallala Aquifer groundwater quality

In a new paper published by the Texas Water Journal (TWJ), a group of researchers for the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS), found that the quality of water being extracted from the Ogallala Aquifer changes in complex and unpredictable ways.

“In some cases, water quality declined and in others water quality improved,” the researchers wrote in the paper’s abstract. Drs. Timothy S. Goebel, John E. Stout and Robert J. Lascano of the ARS’s Cropping Systems Research Laboratory in Lubbock authored “Seasonal changes of groundwater quality in the Ogallala Aquifer” in the journal’s Volume 9 issue. Their research was supported in part by the Ogallala Aquifer Program, a consortium between USDA-ARS, Kansas State University, Texas A&M AgriLife Research, Texas A&M AgriLife Extension Service, Texas Tech University and West Texas A&M University.

The Ogallala Aquifer extends beneath eight states, stretching from Texas to South Dakota, and is among the largest aquifers in the world. In Texas, extraction of groundwater, primarily for cropland irrigation, far exceeds recharge, resulting in a significant decline of the water table. The authors based their research on sampling 20 irrigation wells that spanned five counties of the Texas High […]
