Air Sensors in Puerto Rico: Empowering a Community with Scientific Knowledge
By Christina Burchette
Drop a stone in a placid lake and you’ll notice that the impact of stone hitting water creates a ripple effect that spreads outward in gentle, incremental waves. It is a quiet but powerful image of something we all know to be true: a small act can generate great significance over time.
EPA researchers Ron Williams and Maribel Colón hope to start a ripple effect in Tallaboa-Encarnación, a small community that sits along the Southern Coast of Puerto Rico. Williams, Colón, and EPA’s Caribbean Environmental Protection Division will work with local community action group DISUR (Desarrollo Integral del Sur) to install and maintain low-cost air monitoring devices in Tallaboa-Encarnación. These devices will help community members analyze local pollutant levels and better understand the local environmental conditions.
Researchers are currently building the community’s air monitors in EPA’s Research Triangle Park laboratory. The rectangular devices are about ten inches wide and will collect data on two common air pollutants: total volatile organic compounds (tVOC), which come from sources like vehicle exhaust, and fine particle pollution (PM2.5), which is emitted from motor vehicles, smokestacks, forest fires, and other sources that involve burning.
Once the devices are installed in the area, which is near a highway and several industrial facilities, community members and members of DISUR will participate in a day-long training using EPA’s Air Sensor Toolbox for Citizen Scientists to learn how to use the devices to collect, validate, and summarize environmental data.
Now more than ever, lower-cost air sensors are making air pollution monitoring citizen-accessible. People all over the world are collecting and analyzing local data to better understand air pollution in their communities and to make choices to protect their health. Our researchers’ involvement in the Tallaboa-Encarnación community project is especially important because the community would not have otherwise had access to these types of air monitoring tools and resources.
The small act of installing air monitoring sensors in such a remote community is about more than new air quality data. A community being able to take the fate of their health and environment into their own hands through scientific discovery is an amazing achievement—one that could create significant ripples in the pond of citizen science.
