Regulators say almost all county's groundwater contaminated

Nearly every county in Texas has at least one case of groundwater contamination, according to an annual report outlined in The Texas Tribune. The latest report compiles 2,870 open cases of groundwater contamination, some of which go back decades, according to the Texas Groundwater Protection Committee.

During 2023, 252 new cases were reported that could affect public drinking water. In addition, 289 property owners were notified that such contamination could affect their private wells.

The state relies on groundwater from aquifers for roughly 55% of its water supply. Voters in 2023 approved a $1 billion fund to develop more water resources, including desalination of brackish groundwater.
