Toxic wastewater from oil fields keeps pouring out of the ground in Oklahoma, despite regulatory efforts to stop it.
Salt water laced with cancer-causing chemicals, a byproduct of oil and gas drilling, is spewing from Oklahoma oil wells. A petroleum engineer with over 40 years of experience was hired to help address the issue.
The problem began the previous year, when toxic water poured out of the ground near the small town of Kingfisher, killing crops and trees. Such pollution events, known as "purges," were becoming increasingly common across the state.
When oil and gas are pumped from the ground, they come up with briny fluid called "produced water," which is many times saltier than sea water and laden with chemicals, including some that cause cancer.
By the time the engineer joined the Oklahoma Corporation Commission, the incidents had grown common enough to earn a nickname — purges.
