SALT LAKE CITY — A stormy, wet summer has helped keep harmful ozone at safe levels in the Salt Lake City area.
State environmental officials said Wednesday that there have been only been six incidents this summer of ozone levels surpassing the safe threshold established by the Environmental Protection Agency. Last year, there were 22 incidents.
Bo Call of the Utah Division of Air Quality says ozone levels that often creep up to dangerous levels by midafternoon have been flushed out by frequent afternoon storms and showers this summer.
National Weather Service meteorologist Christine Kruse said there has been twice as much precipitation this summer compared to last year. The average temperature this summer in Salt Lake City has also been five degrees cooler than last summer, the warmest on record since 1874.
