Degrading potable groundwater quality is a growing concern in Texas, as about 15 percent of all domestic wells in the state are at risk due to high salinity, according to a recent Texas A&M AgriLife Research study.

The work of Srinivasulu Ale, AgriLife Research geospatial hydrology assistant professor, and Dr. Sriroop Chaudhuri, his post-doctoral research associate has been accepted for publication in the “Science of the Total Environment” journal.

The study, “Temporal Evolution of Depth-stratified Groundwater Salinity in Municipal Wells in the Major Aquifers in Texas,” was completed using the Texas Water Development Board’s groundwater quality database for the period from 1960 to 2010.

Groundwater withdrawal accounts for about 36 percent of Texas’ municipal water supplies, according to Ale. However, a myriad of water quality issues have been reported from around the state, raising serious concerns over groundwater use due to a rise in concentration of sulfates, chlorides, fluorides, nitrates and total dissolved solids.
