Which of the following is a consequence of pesticide runoff?

Pesticide runoff refers to the movement of pesticides from agricultural fields into nearby water bodies, soil, and groundwater, which can have significant environmental impacts. The contamination of drinking water is a direct consequence of this runoff. When pesticides move off-target due to rain or irrigation, they can enter surface waters (like rivers or lakes) and groundwater supplies that may be sources of drinking water.

These chemicals can pose serious health risks to both humans and wildlife, leading to issues such as acute poisoning, long-term health effects, and ecosystem disruption. As a result, monitoring and managing pesticide use is crucial to protect water quality.

In contrast, aquifer replenishment, prevention of soil erosion, and improved water management do not result from pesticide runoff. Instead, these processes are typically seen as positive environmental practices that can help maintain healthy ecosystems and water cycles.
