Sediment barriers on environmentally conscious construction sites are designed to block sediments from leaving the site. Which material are they primarily intended to stop?

• A. Water
• B. Soil
• C. Air
• D. Wildlife

Answer: (B)

Sediment barriers focus on keeping soil on the site by treating the runoff that leaves it. They’re installed to slow and filter stormwater so loosened soil particles have a chance to settle out before the water travels off-site. The goal is to reduce sediment entering nearby land or waterways, not to stop water itself, and they aren’t designed to block air or wildlife. So the material these barriers are intended to stop from leaving the site is soil.
