Sensor monitoring site

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.

  • 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.
