Incident monitoring sitesEPA 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.
Standard monitoring sitesEPA 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 in more areas but do not provide correct information when humidity is high (eg. during fog). Sensor site information is not displayed on EPA AirWatch when humidity at the site is above 80%. If sensors are not available or showing Poor, Very Poor or Hazardous air quality, please double check the result with a nearby standard site.

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

Altona North air monitoring station has been relocated and is currently being commissioned. Air quality information for Altona North is not currently displayed on AirWatch. EPA advises residents in Altona to refer to nearby sites Brooklyn and Footscray on AirWatch for air quality information in the region. (29 June 2020)
