2 Pa. metro areas have some of the highest air pollution in the U.S.

The American Lung Association (ALA) has released its annual “State of the Air” report.

And several places in Pennsylvania were noted for their rather poor air quality. In fact, the Keystone State in general didn’t do all too well.

According to the report, the Pittsburgh-Weirton-Steubenville, Pennsylvania-Ohio-West Virginia area ranks 12th when it comes to having the worst year-round particle pollution in the United States.

That region also ranked 16th when it came to having some of the worst short-term air pollution in the country, too. Lancaster ranked 22nd overall in this regard as well.

Pennsylvania, on the whole, only saw two of its counties score an A grade when it came to air quality: Somerset and Tioga. The rest were mostly graded Cs, while three counties — Berks, Bucks and Philadelphia — received Fs.

“In ‘State of the Air’ 2025, the metropolitan areas that ranked worst in the country for each of the three pollutant measures are unchanged from last year’s report,” the report says. “Bakersfield, Calfornia tops the list for worst short-term particle pollution for the third straight year.

“Bakersfield also continues to be the metropolitan area with the worst level of year-round particle pollution in the nation, as it has been in 25 of the 26 years of reporting in ‘State of the Air’ — although city residents are exposed to 77 fewer days each year, or two and a half months’ worth, with unhealthy levels of ozone, on average, than they were in 2000.”
