Temporary Air Monitoring Stations | Clean Air Sarnia and Area (CASA)

The Ministry of the Environment, Conservation and Parks (MECP) currently has two temporary air monitoring stations ("Airpointers") located in the Sarnia area.

An Airpointer is a compact air monitoring station that can measure pollutant concentrations on an hourly basis.

The pollutants measured at these stations are provided below. The MECP is verifying data collected by the Airpointers and will be updating results throughout the year.
