The technological advances that led to the “shale revolution” have undoubtedly had a large economic impact on the Texas economy – something state leaders and the oil and gas industry are never shy about pointing out. But the impact drilling has on air quality and public health, that’s something energy-friendly Texas has not been so quick to recognize.
When not managed responsibly, drilling operations can contribute to the formation of ozone, also commonly known as smog. At certain concentrations, this pollution can trigger asthma attacks and cause other severe respiratory illnesses.
San Antonio is one place that’s seeing the clear connection between drilling and lower air quality, thanks to increased drilling just south of the city from the Eagle Ford Shale region. Before 2008, ozone levels in San Antonio had been steadily dropping, but when the shale revolution hit and drilling increased, regional ozone readings started going up. In fact, based on air quality monitor readings from the last three years, San Antonio’s air quality is the 2nd worst in the state. This correlation between drilling and ozone levels has been documented by The University of Texas and the Alamo Area Council of Governments, both of which concluded oil and gas activity in the Eagle Ford Shale is materially impacting ozone levels in San Antonio.
