In the heart of Pacoima, California, a grassroots movement is emerging to combat the dire air quality plaguing this densely populated neighbourhood. Armed with a network of hyperlocal air quality sensors, residents are taking a stand against the pollution that has long affected their health and environment. This initiative, spearheaded by the local group Pacoima Beautiful, seeks to turn the invisible threat of air pollution into a visible reality, empowering the community with data to advocate for change.
The Landscape of Pollution in Pacoima
Pacoima, nestled in Los Angeles’s north-east San Fernando Valley, is surrounded by a maze of highways and industrial sites. With a population exceeding 81,000 crammed into a mere seven square miles, this multicultural and working-class enclave faces some of the worst air quality in the nation. The neighbourhood is flanked by Interstate 5, Highway 118, and Interstate 210, while a regional airport and various factories contribute to the toxic atmosphere.
Long-time resident Jose Luis Salas has witnessed the decline of air quality over his 26 years in the area. “On certain days, even without fog or a breeze, you can see smoke in the streets,” he lamented, reflecting on the struggles he faces while exercising outdoors. Alarmingly, nearly 9% of Pacoima’s residents suffer from asthma, a statistic that underscores the urgent need for local intervention.
Empowering the Community Through Data
The initiative, which began in 2019, has installed a series of sensors throughout Pacoima to monitor air quality in real time. These devices, including the Aeroqual sensors recently attached to Salas’s home, measure pollutants like PM2.5 and ozone, providing invaluable data that local residents can use to advocate for their health and well-being. “Data in the hands of the community is really powerful,” noted Paloma Giottonini, an urban planning professor at California State University, Northridge, who collaborates with Pacoima Beautiful.
The closest regulatory air monitor is miles away, failing to reflect the specific conditions in Pacoima. The data gathered from these local sensors enables residents to highlight the severity of their pollution levels, urging local authorities to take action. “They can come to the city and say, ‘Look at our levels. They’re much higher than everywhere else. Do something about it,'” Giottonini explained.
A Legacy of Environmental Activism
Pacoima Beautiful, the driving force behind the air monitoring programme, was founded in 1996 by a group of concerned mothers who sought to address environmental hazards in their community. Initially focused on litter and toxic fumes from local industries, the organisation has expanded its mission to tackle a range of environmental issues, including climate change.
The group’s efforts have included the implementation of cool pavement initiatives, which involve covering over 700,000 square feet of asphalt with reflective materials to reduce heat absorption. This innovative approach not only combats urban heat but also enhances the overall livability of the neighbourhood, making it safer for residents, particularly the young and elderly who are most at risk from pollution.
The Future of Air Quality Monitoring in a Warming World
The importance of low-cost air quality sensors cannot be overstated, especially as climate change exacerbates pollution levels. In 2020, the devastating impact of wildfires highlighted the necessity for accurate, real-time air quality data. Researchers studying the effects on farmworkers learned that nighttime air quality was often worse than during the day, leading to crucial changes in safety protocols for agricultural workers.
As Pacoima Beautiful continues to expand its monitoring network, the movement is inspiring other communities to take similar steps. In Washington state, for example, a professor helped establish one of the largest rural sensor networks in the nation, demonstrating how local efforts can yield significant improvements in public health.
For residents like Salas, the data generated by these sensors is vital for understanding the environmental challenges they face. “The numbers show that there is more pollution near the freeway areas because of the heavy trucks,” he said, highlighting the ongoing battle against air quality degradation in his neighbourhood.
With the installation of sensors providing critical insights, the community is poised to advocate for a cleaner, healthier future. Salas expressed his hope for the next generation, stating, “I want to leave a better world for those who come after us. My vision is for our children and grandchildren to inherit a cleaner environment.”
Why it Matters
The fight for air quality in Pacoima serves as a beacon of hope for communities facing environmental injustices across the globe. By harnessing technology and local activism, residents are taking charge of their health and demanding accountability from those in power. This grassroots movement exemplifies how empowered communities can make a tangible impact in the face of climate change and pollution, serving as a model for others to emulate. As Pacoima Beautiful continues its vital work, the lessons learned here will resonate far beyond the neighbourhood, igniting similar initiatives in cities battling pollution worldwide.
