Applying pesticides near water bodies poses a significant risk of runoff and contamination. This is primarily because pesticides can easily wash away into nearby streams, rivers, lakes, or groundwater, especially during rainfall or irrigation events. The introduction of these chemicals into aquatic ecosystems can lead to harmful effects on fish, aquatic plants, and other wildlife, potentially disrupting local ecosystems and food chains. Moreover, contaminated water sources can pose health risks to humans and animals if they are used for drinking or recreational purposes.

The risk of runoff emphasizes the importance of following proper application guidelines and buffer zone regulations to minimize environmental impact and ensure the safety of nearby water resources. It is crucial for applicators to consider these factors to protect both the environment and public health.
