Key findings from our investigation into fracking the Barnett Shale
- The Barnett Shale, birthplace of modern fracking, lies beneath 5,000 square miles in North Texas and has 16,000 gas-producing wells.
- The Barnett is the longest-running experiment about what happens when fracking operations move next door to people.
- The Barnett region is more than twice the size of Delaware, and its 26 air monitoring stations leave most of it uncovered.
- Oil and gas emissions vary greatly, making it difficult to assess impacts on health — one Texan uses the phrase "trying to chase air.”
