Over the last two years the nation had more polluted air days than just a few years earlier, federal data shows. While it remains unclear whether this is the beginning of a trend, health experts say it's troubling to see air quality progress stagnate.
That's not quite the case. There were noticeably more polluted air days each year in the president's first two years in office than any of the four years before, according to new Environmental Protection Agency data analyzed by The Associated Press. "What you're seeing is a flattening off of progress as opposed to a major change in the wrong direction," said former deputy EPA administrator Bob Perciasepe, president of the Center for Climate and Energy Solutions.
But they say looser restrictions and lax enforcement would almost certainly reverse the gains that have been made in recent decades, potentially turning what has so far been a modest, two-year backslide into a dangerous trend. Five hundred and thirty-two American metro areas reported a total of 4,134 days in 2018 when the official air quality index passed 100, which means it is unhealthy for people with heart and lung disease, the elderly and the very young. That's about 15% more bad air days per city than the average for 2013 to 2016, America's clean air heyday.
El Paso averaged more than 200 bad air days a year in the 1980s. That dropped steadily to just under 14 a year on average from 2010 to 2016, then ticked up to an average of about 20 over the past two years.
