How to Control Dust

Dust from unpaved roads can account for more than 30% of the total emissions from the property Higher silt contents and vehicle speeds increase visible dust Watering is the most common method of unpaved road dust control Use chemicals only if they reduce the frequency of treatment to the point where they become more cost-effective than watering.
