Special projects monitoring

View the latest air quality index (AQI) and concentration values for data collected from special monitoring projects.

The Katoomba Air Quality Monitoring Station is part of the Blue Mountains and Lithgow Air Watch Project led by NSW Environment Protection Authority (EPA). Blue Mountains and Lithgow Air Watch is a temporary (12-month) project initiated by the local community to measure ambient air quality in the Blue Mountains and Lithgow. The project started in May 2019 and will conclude in May 2020. 

As part of this project, 12 low-cost air quality (KOALA) sensors developed by Queensland University of Technology have been deployed at locations selected by community representatives. The use of KOALA sensors provides a cost effective and easy-to-operate way of observing air pollution trends across the Blue Mountains and Lithgow areas. 

KOALA sensors used in this project do not comply with Australian Standards and only provide indicative measurements of PM10, PM2.5 and carbon monoxide. Current data from the KOALA sensors can be found on the KOALA webpage. Note that this website works best on the Chrome browser. 

Further information regarding the Blue Mountains and Lithgow Air Watch Project can be found on the EPA's webpage.

Incident monitoring data and station information are reported when air quality is measured at specific locations during incidents like bushfires or other air pollution events.

At the request of Fire and Rescue NSW (FRNSW) and NSW Environment Protection Authority (EPA), we deployed three stations to monitor effects on air quality due to an underground fire incident at Kooragang Island .

From February to May, two types of stations were deployed to monitor near-source emissions and general community exposures. All stations measured carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2) and airborne particulate matter, PM10 (particles less than 10 µm in diameter) and PM2.5 (particles less than 2.5µm in diameter).

  • Warabrook Station, which is a community air quality station, currently remains active. It is located approximately 1.4 km south-west of the incident site at the boundary between Mayfield West and Warabrook.
  • Two stations that were located on Kooragang Island to monitor air quality at the incident site were decommissioned at the end of April when FRNSW reported to OEH/EPA that the fire had been extinguished and the operation to contain the incident accomplished.

Data from Warabrook will be provided in near real-time until further notice.
