www.capitalweather.com DC region slashes ozone pollution, meets federal air quality standard The number of unhealthy air days has fallen dramatically, from dozens annually in the late 1990s and early 2000s to just five so far this year. Some rare good environmental news! 🌎View quoted post on X
After decades of efforts to cut pollution, the DC region has finally met federal air quality standards for ozone.
The progress is remarkable: In the late 1990s and early 2000s, we routinely had dozens of unhealthy air days each year. So far in 2026, we've had just five.
A major clean air milestone — and a win for public health. EPA approval is the final step.
