Air quality data on this website are automatically polled from the Clean Air Sarnia and Area monitoring network and are intended for public awareness. Because the data is real time, they have not undergone complete quality control and quality assurance procedures, and so they may contain errors and are subject to change. The real-time air quality data on this web page are considered "unverified data" and should not be used in published documents.

Data integrity and validity may be affected by instrument malfunctions, telemetry connectivity, QA/QC requirements, instrument calibration times or power outages.

Real-time air quality data on this website are not meant for emergency response purposes. This website does not replace or supplement the existing emergency notification and response protocols, including Sarnia-Lambton Alerts.
