Mixing pesticides near wells increases the risk of groundwater contamination.

• A. True
• B. False
• C. Depends on pesticide formulation
• D. Only during rain events

Answer: (A)

Mixing pesticides near a well creates a clear route for contaminants to reach groundwater. If a spill, overflow, or container leak occurs during mixing, the pesticide can move through soil and water downward, potentially entering the aquifer that supplies the well. Groundwater often travels slowly and can carry residues over distances, and many pesticides persist in the environment, so even small releases can contaminate drinking water. While rainfall can worsen transport, the risk is present regardless of weather, making proximity to wells a heightened contamination hazard. That’s why the statement is true.
