Which of these Texan cities is situated on top of the Ogallala Aquifer?

Lubbock is situated on top of the Ogallala Aquifer, which is a critical source of groundwater for agricultural and municipal uses in the region. The Ogallala Aquifer stretches across several states, including Texas, and is known for its vast subterranean water reserves beneath the Great Plains. Lubbock, located in northwestern Texas, relies significantly on this aquifer for its water supply.

In contrast, the other cities listed—Galveston, Corpus Christi, and Brownsville—are located in coastal areas of Texas and do not sit directly above the Ogallala Aquifer. Instead, they typically utilize different water sources, such as surface water or other local aquifers, which are more relevant to their geographic locations and urban needs.
