CPESC Sediment Control Best Practices — Questions and Answers
Question 1: What is the primary purpose of sediment control in construction projects?
- To reduce construction costs.
- To protect water sources and prevent pollution (Correct answer)
- To improve aesthetics.
- To accelerate construction.
Correct answer: To protect water sources and prevent pollution
The primary purpose of sediment control in construction projects is to prevent soil particles, which become sediment when eroded, from entering and polluting nearby water bodies. Sediment can degrade water quality, harm aquatic life, and fill in waterways. By controlling sediment, construction sites protect valuable water resources and comply with environmental regulations.
Question 2: Which of the following is a common method used for sediment control?
- Using concrete barriers.
- Installing silt fences and sediment basins (Correct answer)
- Removing topsoil.
- Increasing project scale.
Correct answer: Installing silt fences and sediment basins
Silt fences are temporary barriers that filter sediment from runoff, while sediment basins are larger, temporary ponds designed to collect and hold sediment-laden runoff, allowing soil particles to settle out before the water is discharged. Both are highly effective and commonly used methods for trapping and containing sediment on construction sites, preventing it from leaving the property.
