To prevent contamination of surface and groundwater, what is a recommended best management practice?

Utilizing terrace and conservation tillage practices is a recommended best management practice to prevent contamination of surface and groundwater. These agricultural practices are designed to reduce soil erosion and water runoff, which can carry pesticides and fertilizers into nearby water bodies. By implementing terraces, farmers create steps or slopes that help slow down water flow, allowing it to infiltrate the soil rather than wash away. Conservation tillage minimizes soil disturbance, maintaining a healthy soil structure that can absorb and filter water effectively.

This approach not only safeguards water quality but also enhances soil health, promoting a sustainable farming system. In contrast, simply increasing the use of chemical pest control can lead to higher risks of contamination if not managed carefully, while avoiding any pesticide application may not always be practical for pest management. Monitoring pesticide levels in water is important, but proactive practices like terrace construction and conservation tillage offer a more direct means of preventing contamination before it occurs.
