Ozone Pollution in Oil and Gas Fields (IMAGE) NOAA Headquarters Caption Sunset over a field in Uintah Basin in Utah, where natural gas and oil development has increased in recent years. A new study by NOAA and CIRES scientists shows that chemicals released into the air by oil and gas activities here spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards.
