A study on air quality shows an improvement in the Fox Cities and Green Bay areas.
The American Lung Association released its annual "State of the Air" report. Spokeswoman Dona Wininsky says Outagamie and Brown counties both received a "C."
She says over a three-year period, there were three ozone violations and one particle pollution violation in each county. She says that's pretty good.
The report covered 2013 to 2015.
Wininsky says around the country, they're seeing lower ozone levels and year-round particle levels. She says they're concerned about the impact that President Trump's proposed funding cuts to the EPA could have on air quality.
