Case Studies and Lessons Learned
May 17, 2022
11:00 am – 12:30 pm PT
Dust palliatives are agents or mixtures that are applied to unpaved roads to reduce airborne dust. The amount of dust, and therefore the type of palliative – or road stabilizer, depends on the climate, amount of precipitation, and surface disturbance. Fugitive dust is known for its impacts to human and wildlife health, yet palliatives also come at a risk of environmental harm. Palliatives can be expensive and can erode quickly if not applied correctly for the right soil conditions. For these reasons, the U.S. Geological Survey and practitioners from the field will provide lessons learned from research pilots and case studies.
