Air Monitoring Station

This historical site is at a closed elementary school in a residential neighborhood on the north side of Butte and very near an operating open pit copper mine. Particulate Matter (PM) 10 and PM2.5 data collected at this site represents population exposure on a neighborhood scale. Continuous PM10 data is used to monitor NAAQS compliance in the local non-attainment area. Continuous PM2.5 data is reported to the Today's Air website and is used for public health protection plans during periods of poor air quality.
