Air Quality

It’s May in Rocky Mountain National Park, but on a mountainside 10,829 feet above sea level, snow is falling. It’s pelting Jim Cheatham, a biologist with the National Park Service. Shrugging off the cold, Cheatham seizes a teachable moment. This snow, he said, holds more than just water.

“Chances are it’s carrying the excess nitrogen we’re talking about,” mused Cheatham.

For the past eight years, the biologist has spent most of his time thinking about how nitrogen pollution is changing the park’s forests, wildflowers, and alpine lakes. He’s also been looking for a way to stop it.

Today on the program we talk with Aspen Public Radio's Elise Thatcher, who was recently in the North Fork Valley reporting on a mobile air quality monitoring study being coordinated by Citizens for a Healthy Community and the Endocrine Disruption Exchange, or TEDX. 

Calling them ‘groundbreaking,’ Governor John Hickenlooper proposed new statewide air quality rules for oil and gas drilling Monday. The rules aim to reduce air pollution from methane emissions.
