Current notices

  • EPA AirWatch, launched in January 2016, was developed to provide accurate and easily accessible air quality information to the community. While air quality data collected from EPA’s monitoring stations is correct, we are working to fix minor faults with how some data is displayed. EPA is continually monitoring this page to ensure viewers are notified about any specific faults of concern. Air monitoring information is also available at the hourly air quality data table.
  • A number of instruments that we use to monitor summer ozone are being taken offline and will not be switched back on until October or November 2016. Mainly in metropolitan Melbourne, they will not supply ozone levels for the EPA AirWatch map or hourly data tables at those locations during this time. (24 June 2016)
  • Monitoring for PM2.5 at Traralgon air monitoring station is offline due to technical difficulties and PM2.5 data is not being collected at this station. EPA technicians are working to fix the problem. The air quality forecast for Latrobe Valley is expected to be GOOD to VERY GOOD. (24 June 2016)
