(Logan-AP) -- Officials in Cache County will try to clear the air today.
The Bear River Health Department and officials with the Division of Air Quality are holding a news conference to talk about exactly how dirty the air up there is.
Logan's air quality was classified as "very unhealthy" last week, but a discrepancy in the monitoring equipment was discovered, so the alert was upgraded to "unhealthy".
Health officials will also explain how Cache Valley's pollution isn't as bad as in other U-S cities.
A strong high-pressure front has sealed pollution in the small valley basin prompting communities to adopt measures to reduce the pollution.
The same strong high-pressure front has also affected air quality in Salt Lake, Davis and Utah counties.
