(EnviroNews Utah) – By January 2010 it was official. Northern Utah had been labeled with the worst air quality in the nation, exceeding all Federal standards for particulate pollution.
The Federal Government’s air quality website “Air Now” ranks the top 5 worst places in the United States for air quality, and in January 2010, all 5 were located in Utah.
Salt Lake City, Ogden, Provo, Logan, and the Washakie Indian Reservation near the Utah/Idaho border all made the list.
Air is considered to be deteriorating when the index for particulate pollution reaches over 35. For several days in January, Salt Lake City’s air quality index rated 142, as compared to 67 for San Francisco, and 23 for Las Vegas.
