To prevent pollution to watercourses, what would be the best solution to control surface water run-off from material stockpiles?

Using silt fences around stockpiles is an effective solution for controlling surface water run-off and preventing pollution of watercourses. Silt fences are designed to intercept sediment-laden stormwater runoff, allowing water to flow through while trapping suspended solids. This helps to reduce the amount of sediment and potential pollutants that could be washed away from the stockpile into nearby watercourses, thereby minimizing the risk of water pollution.

Implementing this method also does not require significant infrastructure changes or extensive modification of the landscape, making it a practical approach for construction sites or areas where materials are stored. Additionally, the use of silt fences can be combined with other protective measures to create a more comprehensive strategy for managing surface water run-off effectively.

Other methods, while potentially helpful in certain scenarios, may not specifically address the issue of controlling sediment and preventing pollution as effectively as silt fences do. For instance, suction pumps may remove excess water but do not prevent pollutants from reaching watercourses. Tarps can cover stockpiles to prevent direct exposure to rain, but if water does accumulate around the stockpile, it might still lead to run-off issues. Creating drainage ditches can help redirect water, but without proper sediment control measures in place, it might not adequately prevent sediment
