Wildfires in Canada have once again spread a haze over parts of the U.S., including Williams County, harming the air quality. As of Wednesday, all of Williams County had an air quality rating of unhealthy, that’s according to the Environmental Protection Agency. However, the worst was yet to come as by noon an interactive map showed a significant portion of the county was in the very unhealthy rating, including the villages of West Unity, Pioneer and Montpelier as well as the northeastern part of Bryan.
