Salty, Oily Drinking Water Left Mouth Sores. Okla. Refused to Find Out Why.

"When one couple’s water turned toxic, state oil regulators delayed key tests that could find a source of contamination. The state didn’t tell the couple for over a month that tests showed their drinking water was contaminated with high levels of barium, which can cause heart problems."

"In the summer of 2022, months after Tammy Boarman and her husband, Chris, moved into their newly built “forever home” 30 miles from Oklahoma City, the plants in their yard began to turn yellow. The shrubs wilted, though Tammy watered them often. And the couple began to notice a salty taste in their drinking water.

The water came from a private well, drilled the year before, and they hoped that the bad taste would fade with time and with the help of a water softener.

But the problem grew worse. Their ice maker expelled large clumps of wet salt, which, when rubbed, dissolved into an oily, foul-smelling substance.

The couple knew that some oil and gas extraction took place nearby. Down dirt roads and behind stands of oak trees in their neighborhood, pump jacks nodded up and down, pulling up oil. This is a common sight in Oklahoma. Several studies estimate that about half the state’s residents live within a mile of oil and gas wells."
