What practice can help prevent pesticides from reaching groundwater?

1. Using pesticides at higher than recommended amounts

2. Keeping storage facilities away from water sources

3. Mixing pesticides in open areas

4. Ignoring runoff during application

The correct answer is: Keeping storage facilities away from water sources

The practice of keeping storage facilities away from water sources is vital in preventing pesticides from contaminating groundwater. When storage facilities are located near water sources, any spills, leaks, or accidents can lead to pesticides directly entering the water supply. Groundwater is a critical resource, and protecting its integrity requires thoughtful management of where pesticides are stored. By situating storage facilities further away from waterways and sources of water, the risk of contamination is greatly reduced. This practice not only safeguards the environment but also supports public health by ensuring that drinking water remains free of harmful chemicals. Effective site selection for storage facilities is a key preventative measure in overall pesticide management strategies. In contrast, higher pesticide application rates can lead to increased runoff, while mixing pesticides in open areas may expose them to environmental conditions that could promote groundwater contamination. Ignoring runoff during application neglects a major pathway through which pesticides can infiltrate soil and potentially reach groundwater supplies.
