Kalgoorlie-Boulder is a major industrial and mining centre in the Goldfields region.
The combination of the dry climate, storage of mine waste near the city, unsealed roads and degraded land within and surrounding the city have all contributed to the dust problem.
The dust or solid airborne particles are generated and dispersed into the air by processes such as handling, crushing and grinding of organic or inorganic materials such as rock, ore, coal or grain and stockpiling of materials.
