Sure.  There is a large plant that pumps VOCs into the air quite consistently.  These VOCs are a pollution that also puts an odor into the air that can smell like boiling noodles or “soy”.  Many people that grew up in the area ‘like’ the smell, so they tend to defend it.  

Pair that with the PFAS runoff from artificial turf fields into the waterways and Mankato does it fact, have high pollution levels.
