How do sediment and erosion control measures protect water quality?

• A. They increase water flow
• B. They prevent sediment runoff into water bodies
• C. They promote aquatic life sustainability
• D. They enhance water clarity

Answer: (B)

Sediment and erosion control measures are essential tools in protecting water quality primarily by preventing sediment runoff into water bodies. When sediment from construction sites, agricultural lands, or disturbed areas is allowed to move freely, it can wash into rivers, lakes, and oceans during rainfall or irrigation events. This runoff contains not only soil particles but also attached pollutants, including nutrients, pesticides, and heavy metals, which significantly degrade water quality. By effectively capturing and managing sediment before it can reach these water bodies, control measures help maintain a cleaner environment, safeguarding aquatic ecosystems and preventing issues such as algal blooms, which can be fueled by excessive nutrients in water. Thus, the implementation of these measures is crucial for water quality protection and overall environmental health.
