The American Lung Association has released a report titled “Something in the Air: Bridging the Air Quality Data Gap with Satellite Technology.” The study suggests that Forsyth County, Georgia, may have unhealthy levels of particle pollution. Currently, there are no ground-based monitors tracking particle pollution in this area.
The report underscores the potential for satellite-derived data to enhance the U.S. air quality monitoring network. It focuses on fine particulate matter (PM2.5), known to be harmful to human health. Emerging technologies like satellites can provide critical air quality information to communities lacking official monitoring data.
Forsyth County is located near Atlanta's northern edge and is part of northwestern Georgia's warm, humid woodlands. With a population exceeding 250,000, it is one of Georgia’s fastest-growing counties due to economic opportunities and proximity to Atlanta. The Atlanta Metro Area ranks as the 48th worst for annual particle pollution according to the 2024 “State of the Air” report.
Danna Thompson, director of advocacy for the American Lung Association in Georgia, stated, “The rapid growth of Forsyth County has led to increased local air pollution from construction, traffic and residential energy use. In addition, the location of Forsyth County makes it highly susceptible to air pollution due to its presence in the Atlanta metro area.” She added that while there is no official monitor in Forsyth County, satellite data indicates concerning levels of particle pollution. "Our hope is that this report results in more communities having valuable information about air quality levels so they can better protect their health."
Fine particle pollution consists of tiny solid and liquid particles present in the air we breathe; these particles are significantly smaller than a strand of human hair. Sources include wildfires, wood-burning stoves, power plants, and vehicle emissions. Such particles can trigger serious health issues like asthma attacks and heart problems and even lead to lung cancer or death.
The report calls on various entities including EPA and states for action regarding air quality issues.
