Causes of Dust

Dust is made up of tiny, solid particles ("particulate matter") floating in the air. Dust can be generated and released into the air as a direct result of human activities such as:

  • Construction
  • Land development
  • Gravel production
  • Mining
  • Landscaping

Blowing dust so thick that it's hard to see the mountains would suggest there is a dust problem.

NOTE: Dust particles are illuminated and appear thicker when you are looking towards the sun (typically in the early morning and evening hours).
