Collaborating with Local Communities to Measure Air Pollution

By Michaela Burns

I am no stranger to air pollution. Since I grew up in New York City, my walk to school every morning put me in constant contact with car exhaust and smoke rising from the vendor stations that lined the sidewalks. None of these experiences ever struck me as odd. They were just a part of the city’s charm! We had the Empire State Building, the Statue of Liberty, and we had air pollution. On particularly smoggy days, when I could barely see the city from my window, I always comforted myself with the fact that it was a problem far out of my league. After all, I was just an ordinary kid, not a scientist — what could I do to help? Nothing of course.

Once I started working at EPA, I found out that I had been completely wrong. Managing air pollution is a big job, but it can be made easier when the whole community gets involved. We call it “citizen science” — where people without a background in research can use scientific tools to address problems in their environment. To support this fast-growing field, EPA’s Science to Achieve Results (STAR) program is funding six grants to evaluate how effective low-cost, portable air sensors are when used in communities.

EPA grant winners at the Massachusetts Institute of Technology will use community-based air sensors to measure air quality and volcanic smog (“vog”) exposure on the Island of Hawai‘i (“the Big Island”). Up the coast at the University of Washington, researchers plan to deploy air sensors in student-directed studies examining heavy wood smoke impacts in their rural community. The team will work in partnership with Heritage University, whose students represent the local population of predominantly Yakama Nation and Latino immigrant families, to identify effective ways to communicate pollutant results to a broader audience. And this is just a sample of the diverse group of projects being done to help make air sensors more available to the public across the U.S. Other efforts include:

Carnegie Mellon University. Researchers will investigate the accuracy and reliability of existing air sensors, as well as their efficacy when put to use in Pittsburgh communities.

Kansas State University. Researchers will investigate if communities in South Chicago become more engaged in learning about their environment if they are provided with low-cost air sensors and the information generated by them.

Research Triangle Institute This research team will investigate how low-cost sensors can be used to help the Globeville, Elyria, Swansea (GES) community north of Denver, Colorado measure and understand data indicating the air quality in their neighborhood. The team will also evaluate the effectiveness of how information is presented to enable residents to understand their exposure to indoor and outdoor air pollutants and potentially empower them to take action to protect their health.

South Coast Air Quality Management District. This research team will provide local California communities with the knowledge necessary to select, use, and maintain low-cost, commercially available air monitoring sensors and to correctly interpret sensor data. The group will communicate the lessons learned to the public through a series of outreach activities.

By supporting the development and deployment of air monitoring technology, EPA is empowering ordinary citizens to take action against air pollution. Looking out for your community can be as easy as using our air sensor toolbox for citizen scientists to find out how to monitor the air quality in your neighborhood. With tools in reach, there’s no reason not to become a citizen scientist today!
