TCEQ staff use computer models to simulate the meteorological conditions and chemical reactions that contribute to the formation of air pollutants and to predict how air quality in a region will be affected by economic and population growth, and by reducing pollution emissions.
Barnett Shale is a hydrocarbon-producing geological formation consisting of sedimentary rocks and stretching from the city of Dallas west and south, covering 5,000 square miles and 21 counties. Since 2002, gas production activity in the area has experienced significant growth and the TCEQ has been improving emissions data from oil and gas production and is conducting in-depth measurements to fully evaluate potential health effects.
The Eagle Ford Shale is a hydrocarbon-producing geological formation extending over 24 counties. It stretches from the Mexican border between Laredo and Eagle Pass up through counties east of Temple and Waco.
