What is an effective approach to minimize pollution during highway construction?

Implementing comprehensive stormwater management strategies is an effective approach to minimize pollution during highway construction because these strategies are designed to manage the quantity and quality of water runoff generated during and after construction activities. During highway construction, disturbances to the soil surface can lead to increased sediment and pollutants being washed into nearby water bodies.

By utilizing techniques such as silt fences, sediment basins, and proper grading, construction teams can effectively reduce the amount of sediment entering waterways. Additionally, strategies may include the use of bioretention areas, permeable pavements, and vegetated swales that not only help to filter pollutants but also allow for the natural absorption of water into the ground, thereby reducing harmful runoff.

These measures are crucial because they address both immediate and long-term environmental impacts, ensuring not only compliance with regulations but also protection of local ecosystems. By taking stormwater management seriously, construction projects can mitigate negative impacts on water quality and promote more sustainable practices in civil engineering.
