Drilling in Permian Basin linked to high ozone levels in New Mexico park

Oil and gas drilling in the Permian Basin is causing excessive ozone pollution at Carlsbad Caverns National Park, a new study reveals.

Sharon Udasin reports for The Hill.

In short:

• The study found summer ozone levels at Carlsbad Caverns frequently exceed EPA health standards, linking this to increased drilling in the Permian Basin.
• Researchers identified oil and gas extraction as major contributors to high ozone levels, with nitrogen oxide emissions from drilling operations being significant.
• The study suggests electrified, grid-powered drill rigs could help mitigate ozone pollution.

Key quote:

"Our measurements confirm that activity such as drilling and natural gas flaring is a major driver of the high ozone levels we see."

Why this matters:

Ozone pollution can cause asthma and other health issues and harm crops and ecosystems. Understanding its sources helps in developing strategies to protect both human health and the environment.
