Wildfires, industrial sources contribute to ozone problems in the Eastern Sierra Nevada
By Summit Voice
SUMMIT COUNTY — Devils Postpile National Monument in the eastern Sierra Nevada is about as far as you can get from California’s industrial urban centers, yet air quality at the site has suffered in recent years as pollution blows in from other parts of the state, according to a new U.S. Forest Service-led study.
The monument, near the resort town of Mammoth Lakes, features one of the best examples of columnar basalt formations and is also a gateway to High Sierra wilderness areas bordering on Yosemite National Park.
Ozone precursors (nitrogen oxides and volatile organic compounds) from wildland fires, as well as ozone from the Bay Area and Central Valley resulted in exceedances of federal air quality standards, as well as state air quality standards during the 2007-2008 study period, at levels that pose a risk to sensitive individuals and indicate a need for long-term ozone monitoring.
