Efforts to effectively monitor air quality increase health awareness in Oregon’s Columbia River Gorge

Wildlife smoke has become an issue in Oregon’s Columbia River Gorge after two large wildfire events (in 2017 and 2020) led to record-shattering hazardous air quality index levels. In addition, cherry and pear orchard waste historically has been burned in the area, and no regulations exist on wood-burning stoves. Microscopic particles from smoke can penetrate deep into lungs, causing issues ranging from burning eyes and runny nose, to aggravated chronic heart and lung diseases.

Prior to 2020, the Gorge relied on a single air quality monitor for all of the region’s air quality data. The Columbia Gorge spans 80 miles and includes geographical features that can change weather patterns, creating dozens of micro-climates. Localized air quality data is critical for the health and economic viability of the region.

Oregon State University Extension faculty and staff in the Gorge have partnered with local entities to improve response to wildlife smoke. Projects have included:

• Researching and putting into practice alternatives to burning and smoke mitigation strategies
• Producing a regional community response plan for smoke
• Purchasing, installing and maintaining 10 new air quality monitors for the region

The air quality monitors have been installed at schools and orchards across the area, and a website shares their data, updating the air quality index numbers every five minutes. A team shared the new monitoring network and website at community meetings and presentations (including at the schools where monitors have been installed), helping to increase community air quality literacy. Area students will even be helping to develop messaging for smoke-sensitive and vulnerable groups.

Pinpointing the air quality index with geographically dispersed monitoring sites enables the community response team to provide timely, accurate and locally relevant data and health messaging that enables employers, administrators, community members and tourists to make critical decisions about work and school operations, as well as safe recreation in the community, ultimately aiding health and wellness of the local population.
