We display information about Victoria’s air quality on EPA AirWatch.

EPA has monitoring sites in population centres around Victoria.
Most of our air monitoring sites are next to roads. This is because most Victorians live and work close to roads.
EPA and VICSES can also deploy equipment to monitor air quality nearby an incident like a fire.
We also collect data from a citizen science project. The Inner Melbourne Air Monitoring project sees citizen scientists working with us to help build an understanding of air pollution impacts.
The air quality where you are might be different to what you see on EPA AirWatch, even if there’s a monitoring site close to you. This is because there are many factors that can affect air quality. For example, wind direction and smoke from wood fires.

Note that Kingsville, Newport and Spotswood are temporary air monitoring sites that are part of a citizen science project.
Since 22 July, EPA's equipment near the Stevensons Brothers Industries (SBI) landfill in Ballarto Rd, Cranbourne, has been monitoring hydrogen sulphide in the air every 5 minutes. The graph below shows the results from 22 to 26 July.
EPA has analysed these results. We found most hydrogen sulphide concentrations were either unable to be measured because they were too low or they were at 0.0 parts per million (ppm). On 23 July 2022, there was one result of 0.2 ppm measured within a 5 minute period. These levels are not expected to cause long term adverse health effects.

Data on EPA AirWatch comes directly from our air monitoring stations using various types of monitoring equipment and methods. This data may be adjusted later according to set criteria to account for instrument errors, power interruptions and other technical issues.
EPA aims to locate our ambient monitoring stations so they give a good representation of the air quality experienced by the public. As most of the Victorian population lives and works close to roads, most of our stations are in population centres next to roads. This can mean we do not always comply with one of the requirements of the Australian Standard for siting (AS 3580.1.1), which specifies that air monitoring stations should be more than 50 metres away from a road. Currently, Footscray is the only EPA air monitoring site that meets this requirement.

Alphington: Monitoring for PM10 is offline due to routine maintenance and no PM10 data is being collected at this site. EPA expects data to become available on the website from 5pm, 06/06/2023. The air quality forecast for Melbourne is expected to be GOOD. (5th June 2023)
Spotswood: Monitoring for PM2.5 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. (1st June 2023)
