Why should you avoid filling pesticide equipment near surface waters or wells?

• A. Because it could contaminate surface water or wells due to slope or other conditions
• B. Because it reduces pesticide efficacy
• C. Because it increases the cost of operation
• D. Because it complicates recordkeeping

Answer: (B)

Preventing contamination of water sources is the key reason. Spills, leaks, or overflow during filling can flow into surface waters or move through soil to wells, especially when there’s a slope or permeable soil. Keeping refilling away from streams, wells, and other water bodies, and using an impermeable, contained area, reduces the risk of pesticide reaching water supplies and protecting drinking water and aquatic life. The other choices miss the main priority here—it's about preventing water contamination, not about efficacy, cost, or paperwork.
