Live Air Quality Monitoring
As part of Cadia’s ongoing commitment to transparency and accountability with our local community, we are monitoring air quality levels around the clock at four strategic locations on and around our site and providing real-time, accessible data and reporting to the public.
At Cadia, we are committed to maintaining air quality within the required limits of 50 micrograms per cubic meter of Particulate Matter (PM) 10 and 25 micrograms per cubic meter of PM2.5 for any 24-hour period to assist in minimising the impact that our activities could have on the local community and the environment. This monitoring also determines the efficacy of our control measures and ensures we are compliant with consent and licence conditions.
More information about how we capture and report, as well as the data we report on, is available below.
If you have any concerns with this monitoring and reporting, please contact cadia@newmont.com

About the data
How we capture and report
Specialised air quality monitors (BAM) located at four strategic areas around the perimeter of Cadia’s site capture a reading of the concentration of particulate matter in the air and create a 1 hour average reading for air quality. The readings are provided through to a to a central database where levels are actively monitored. The hourly and 24-hour averages of these readings are continuously updating and can be viewed in the dynamic charts above, or by clicking on the monitor locations map. Data is transferred from the monitors via the Telstra mobile network.
Beta Attenuation Monitor: The BAM automatically measures and records ambient particulate mass concentration levels using the proven principle of beta ray attenuation.
Note:
Unvalidated data: The data displayed is unvalidated data. ‘Unvalidated data’ refers to measurements or readings that haven't been thoroughly checked to confirm their accuracy.
Data availability: Data is transferred via the Telstra mobile network and can be affected by power outages or mobile network disruptions. Data is saved locally on the monitors and updated to the website when communications are re-established.
Negative values: Raw data can display negative values that are within the error margins of the instrument calibrations.
The data we report on
The air quality monitors capture and report on PM2.5 and PM10 pollutant levels.
PM stands for ‘particulate matter’ and is generally classified according to the size of the particles. For context, the diameter of a human hair is approximately 50-70 micrometers (um).
· PM10 - Particles less than 10um in diameter
· PM2.5 - Particles less than 2.5um in diameter
· PM1 - Particles less than 1 micrometre in diameter
· UFPs - Particles less than 0.1 micrometres in diameter: called ultrafine particles. Note: PM10 contains PM2.5, PM1, and UFPs.
Air pollution is caused by (EPA NSW website – About air pollution)
natural sources such as bushfires, dust storms, sea salt and pollen
domestic activities such as burning wood fires, including using wood heaters, fuel-powered garden equipment, and portable fuel containers
commercial businesses such as spray painters, printers, quarries, service stations
industrial activities such as coal and metal mining, oil refining and power generation
on-road motor vehicles such as buses, cars and trucks
off-road vehicles and equipment such as dump trucks, bulldozers and marine vessels
