Ambient Monitoring


For more information, contact Chuck Hyatt, Manager Air Quality Monitoring at 701.328.5188.  

The Division of Air Quality has the primary responsibility for protecting the health and welfare of North Dakotans from the harmful effects of air pollution. The Air Quality Monitoring branch ensures that the ambient air quality in North Dakota is better than the levels required by the state and federal Ambient Air Quality Standards.  To address this responsibility, the Department operates a network of ambient air quality monitors.

  Theodore Roosevelt National Park - Air Quality Monitoring Sites

In addition to the ambient air quality monitoring sites operated by the Department, four industrial sources of air pollutants operated air quality monitoring sites within their immediate spheres of influence. The site locations selected are based on computer dispersion modeling and prevailing wind directions.
