What is the best method for protecting groundwater from pollution?

1. Using filtration systems

2. Preventing contamination

3. Monitoring water quality

4. Applying herbicides

The correct answer is: Preventing contamination

Preventing contamination is the best method for protecting groundwater from pollution because it emphasizes proactive measures that help ensure pollutants never enter the groundwater system in the first place. This approach can include establishing buffer zones, proper waste disposal, and educating the public about responsible pesticide and chemical use. While using filtration systems can help treat water that is already contaminated, it does not prevent the initial contamination of groundwater. Monitoring water quality is essential for assessing the status of groundwater and detecting contamination but does not stop pollutants from entering. Applying herbicides, although sometimes necessary, can contribute to groundwater pollution if not done carefully, thus highlighting the importance of prevention over intervention after contamination occurs. Overall, the focus on preventing contamination not only protects groundwater resources but also promotes safer practices that benefit both human health and the environment.
