How Last Century’s Oil Wells Are Messing With Texas Right Now
Ranchers and regulators are contending with uncontrolled leaks from thousands of abandoned oil and gas sites that could render some land “functionally uninhabitable.”

Water testing crews looking for contaminants collect samples pumped from a shallow aquifer beneath Ashley Watt’s cattle ranch in Crane County, Texas.

Her family owns a ranch larger than Manhattan that’s home to hundreds of oil and natural gas wells. Her Twitter handle is “Frac Sand Baroness.”
That’s what made it all the more jarring almost three weeks ago when Watt began publicly railing against one particular oil driller for leaks on her land. Noxious wastewater from oil drilling began leaching across the ground, endangering people and livestock. By her count, the pollution has killed four cows and two calves so far. Chevron Corp., which drilled the 1960s-era wells that polluted Watt’s land, brought in earth-moving equipment and a well-control crew, even though it had sold most of its interests there years ago. It took 10 days to halt the first leak. Given the hundreds of other aging wells dotting the land, it’s done little to put Watt’s mind at ease.
