Incident monitoring sites

EPA and VICSES can deploy equipment to monitor air quality near an incident like a fire. Incident sites give us immediate data about impacts to air quality and are used to make decisions about what EPA and other agencies do next.

Pollutant concentrations

Standard monitoring sites

EPA has monitoring sites in population centres around Victoria. 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.

Sensor monitoring sites

Sensor sites allow us to get an indication of air quality but may not provide correct information when humidity is high (for example, during fog).

If sensors are not available or showing poor air quality, you can check the air quality near you with this self assessment guide. Find out how to protect your health from air pollution.

  • How to read the tables

    A dash (-) means we don't monitor for that pollutant at that site

    Not Available (NA) means we usually monitor for that pollutant at that site but the data is not available at the moment

  • Disclaimer

    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.
