What is a recommended control measure for disturbed soil after demolition?

• A. Allow the soil to dry completely
• B. Apply water to the disturbed soil
• C. Cover the soil with tarps
• D. Leave the soil exposed

Answer: (B)

Applying water to disturbed soil after demolition is an effective control measure because it helps to suppress dust emissions. When soil is disturbed, especially during activities like demolition, loose particles can easily become airborne if they are dry. Moistening the soil adds weight to the particles, which reduces the likelihood of dust being released into the air. This practice is crucial for minimizing air quality impacts and protecting the health of workers and nearby residents, as it directly addresses the dust problem created by the disturbance.

In addition to controlling dust, applying water can also aid in soil stabilization, which is beneficial for safety and environmental concerns. The water helps bind the soil particles together, making it less prone to erosion and further disturbance.

Other measures such as allowing the soil to dry, covering it with tarps, or leaving it exposed do not effectively address the immediate dust generation issue. In fact, letting it dry can exacerbate the dust problem, while tarps may not be practical for larger areas, and leaving soil exposed increases the risk of dust emissions and erosion.
