Clearing the air over northern Michigan pollution

By Kurt Williams

Air quality in northern Michigan was bad on Jan., 21. At least that’s what the weather app on Sharon Emery’s phone reported. The ominous warning “Unhealthy Air Quality for Sensitive Groups” hung above the day’s current conditions of clear skies and 27 degrees. Emery has a place in Cheboygan, on the shore of Lake Huron in northern Michigan. It’s not  known for poor air quality, especially in winter.

With every gas-powered car and every traditional wastewater treatment plant, a little nitrogen pollution gets released into the atmosphere. Scientists say it settles into the soil and may even lead to toxic algae blooms that kill fish.
