What is one step you can take to prevent pesticides from reaching groundwater?

1. Use pesticides in larger amounts than directed

2. Ensure pesticide storage is more than 100 feet from wells

3. Apply pesticides during rain

4. Mix pesticides right next to water sources

The correct answer is: Ensure pesticide storage is more than 100 feet from wells

Ensuring that pesticide storage is more than 100 feet from wells is an effective step to prevent pesticides from reaching groundwater. This practice creates a buffer zone that reduces the risk of accidental contamination from spills or leaks during storage. By keeping pesticides at a safe distance from water sources, the potential for these chemicals to percolate into the groundwater supply is minimized. Maintaining this distance is a crucial part of pest management and environmental safety, as groundwater is a significant source of drinking water and essential for many agricultural and ecological systems. This proactive measure aligns with best practices in pesticide management, thus protecting both human health and the environment.
