The Clean Air Sarnia and Area (CASA) monitoring network is a combination of continuous (real-time) and non-continuous air monitoring stations. Continuous monitoring provides access to the CASA network's most current hourly air quality data. Non-continuous monitoring involves collecting samples which are sent for laboratory analysis. This air quality data is provided in a report format when the laboratory results become available.
The table below lists CASA's air monitoring station locations and the parameters measured at each station.
