How do herbicides pollute your drinking water?

Herbicides can pollute drinking water through runoff and leaching into groundwater. When applied to agricultural fields, rain or irrigation can wash these chemicals into nearby streams, rivers, or lakes, contaminating surface water sources. Additionally, herbicides can seep through the soil into groundwater, which may eventually be tapped for drinking water supplies. This pollution poses risks to human health and the environment, as many herbicides are toxic and can disrupt aquatic ecosystems.
