"Currently, Utah has the worst air quality in the country, according to a U.S. Environmental Protection Agency map"
I would say the winter inversion that is bogging SLC yet again is one of the biggest downfalls of living in Utah. The opposing hot and cold air pressure traps all of the pollution from the city and all of the pollution blown in from LA gets trapped in the valley bowl with no where to go. For this reason Utah has ranked #1 for worst air quality in the nation. This weeks red days have seemed particularly grueling, I've never seen so many people walking and jogging with dust masks in the 4 winters I've been here.
