Toxic wastewater from oil fields continues to pour 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. This toxic water, also known as "produced water," is many times saltier than the sea and laden with chemicals, including some that cause cancer.
A petroleum engineer with over 40 years of experience in the oil fields was hired to help address the issue, which state regulators did not fully understand. The problem had been ongoing, with thousands of gallons of toxic water pouring out of the ground per day, killing crops and trees, and spreading across acres of farmland.
Such pollution events were not new, but they were occurring with increasing frequency across the state, earning a nickname - "purges".
