WOODS CROSS - The air quality along the Wasatch front in Davis and Salt Lake Counties is among the worst in the nation - again.

According to the EPA's online Air Quality Index (AQI), the Salt Lake/Davis area ranked 3rd worst in the country on Friday, behind only Visalia and Modesto, California.

Utah's AQI reached 107 according the EPA website, which reflects an orange "USG" (unhealthy for sensitive groups") rating.

"Unsafe groups" include people with respiratory illnesses, the elderly and young children, according to the EPA site.

People within the "unsafe groups" are warned to stay indoors when the AQI reaches such levels during an inversion.

Such air quality is a problem unique to Utah and other areas where there are a lot of cars and cold temperatures.

Utah Division of Air Quality spokesperson Donna Spangler told the Clipper it's a problem that grows over time.

"Day after day, it adds up," said Spangler. "As the inversion persists, all the pollution from cars, homes and businesses sticks around."

The good news is, occasional storms can scrub Utah's valleys of all that smog.

One such storm was expected to hit Utah by the weekend.

In the mean time, Spangler says limiting driving is the only solution to helping improve the air quality.
