Two companies provide the majority of drinking water for Jarrell, TX. The first, Jarrell Schwertner Water Supply Company, obtains the majority of its water in the form of ground water drawn from the Edwards Aquifer. The other company is the Central Texas Water Supply Corporation which gets most of its water in the form of surface water drawn from Lake Stillhouse Hollow. The Texas Commission on Environmental Quality conducted a thorough analysis of both sources of water and results indicate that some of the water sources can be susceptible to certain types of contaminants.
