EPA Warns Georgians to Stay Indoors as Air Quality Reaches ‘Unhealthy’ Levels

GEORGIA – The U.S. Environmental Protection Agency (EPA) is urging residents across Georgia to limit time outdoors after air quality monitors detected “Unhealthy” levels of fine particulate matter, known as PM2.5, in several counties.

According to the Air Quality Index (AQI), concentrations of particle pollution have climbed high enough to pose health risks to the general population. Exposure to elevated PM2.5 can trigger or worsen respiratory and cardiovascular conditions, including asthma, heart attacks, and strokes. Health officials note that the risks are especially significant for vulnerable groups such as young children, older adults, pregnant women, and people with existing heart or lung disease.

The AQI measures particle pollution on a scale from 0 to 500. Levels between 101 and 150 are considered “Unhealthy for Sensitive Groups,” while readings from 151 to 200 fall into the “Unhealthy” range for everyone. Values from 201 to 300 are classified as “Very Unhealthy.”

Counties reporting “Unhealthy” conditions on Thursday include Cherokee, Pickens, Dawson, Barrow, Hall, and Rockdale, with some locations reaching readings as high as 166. The spike is tied to increased PM2.5 pollution, which can originate from combustion sources such as vehicle traffic, industrial facilities, wood-burning, and wildfires.

The Georgia Recorder has previously reported that Atlanta is among the top U.S. cities for spikes in particle pollution, often driven by smog and traffic emissions.

A spokesperson for the Georgia Department of Natural Resources told Newsweek that the recent surge in PM2.5 is “most likely due to local nearby burns with perhaps some mixed-in smoke from agriculture burns around the Southeast,” adding that stagnant weather conditions—light winds, dry air, and a persistent high-pressure system—are contributing to the elevated readings.

AirNow, the EPA’s public air-quality reporting platform, warns that particle pollution can cause serious health effects ranging from coughing and reduced lung function to asthma attacks, heart attacks, strokes, and premature death among people with chronic heart or lung disease.

The EPA advises residents in affected areas—particularly those with medical vulnerabilities, outdoor jobs, or strenuous daily routines—to reduce or avoid outdoor activities until air quality improves. Those who must be outside are encouraged to opt for lower-intensity activities, such as walking rather than running, to limit inhalation of fine particles.

Real-time AQI conditions can be monitored on the AirNow map, which will continue updating throughout the day.
