Some of EPA’s air quality measurement and reporting methods are accredited by the National Association of Testing Authorities (NATA). Our NATA accreditation number is 15119.

Air quality information is available from EPA AirWatch.

Location of EPA’s air monitoring sites

We put our air monitoring sites in areas that represent the air quality experienced by most people. For example, most Victorians live and work close to roads. This is why most of our air monitoring sites are in population centres next to roads.

The Australian Standard (AS 3580.1.1) specifies that air monitoring stations should be more than 50 metres from a road. Currently, only our Footscray air monitoring site meets this requirement.
