Dust Deposition Gauge Monitoring
Dust deposition gauges (DDGs) are a low-cost, low-maintenance tool ideal for proving dust compliance, managing nuisance complaints and initial monitoring.
ENVSS fabricates robust, rust proof DDGs at our WA facility. We are able to customise these units for deployment in most environments, suiting them to the needs of your site and project

What Is Dust Deposition?
Dust deposition refers to the airborne particles that settle on surfaces over time. Settlement can accumulate quickly in industrial, construction and mining environments, where activities like earthworks and material handling generate significant amounts of dust.
While not always a direct health hazard, deposited dust often leads nuisance complaints, visibility issues and compliance breaches if not properly managed. Monitoring this type of dust is essential for understanding how much material is leaving your site and where it’s settling.
How Dust Deposition Gauges Work
DDGs feature a cylindrical container mounted in an open area, filled with a preservative solution that captures and retains settling dust.
They are passive monitoring devices, collecting data naturally overtime. They measures the amount of particulate matter that settles out of the air and onto a collection surface over a period of 30 days.
Once the sampling period is complete, the solution is collected and sent to a laboratory for analysis. The results are typically reported in milligrams per square metre per day (mg/m²/day), a practical representation of how much dust is depositing in a given area.
While not always a direct health hazard, deposited dust often leads nuisance complaints, visibility issues and compliance breaches if not properly managed. Monitoring this type of dust is essential for understanding how much material is leaving your site and where it’s settling.
Why Use Dust Deposition Gauges?
DDGs are often used in environmental impact assessments, compliance monitoring and complaint investigation processes. They are particularly useful for:
Assessing off-site dust drift
Tracking baseline conditions before major works
Demonstrating compliance with site-specific limits or licence conditions
Unlike real-time monitors that detect airborne concentrations (e.g. PM10, PM2.5), DDGs give a longer-term average of how much dust is actually settling on surfaces. Nuisance-related complaints often arise from long-term issues, making the DDG a suitable choice for investigation.
Regulatory Requirements in Western Australia
In Western Australia, there are no limits or regulations at the state level for dust deposition. Instead, you must consider site-specific licence conditions, Environmental Protection Authority (EPA) guidance and local council approvals. These may impose limits on dust fallout.
The commonly accepted limit is 120–133 mg/m²/day, derived from national and international nuisance dust guidelines.
If your site operates under a Ministerial Statement, Works Approval or Environmental Licence, regular dust deposition monitoring may be an ongoing condition.
