AIR & WATER QUALITY
Barnett Shale air is the most monitored in the nation
It may not be widely known, but the air in the Barnett Shale area of North Texas is the most monitored air in the U.S. The Texas Commission on Environmental Quality (TCEQ) has installed a system of 15 permanent automated gas chromatograph (AutoGC) stations in the Barnett Shale area that take air samples every hour, 24 hours a day, 365 days a year. The data is available to the public online. In addition to these AutoGCs, TCEQ also operates a network of volatile organic compound canister air sampling stations that also take air samples.
