Which statement informs applicators of the danger of surface water contamination?

• A. Ground Water Advisory
• B. Surface Water Advisory
• C. Practical Treatment
• D. Use Classification

Answer: (B)

A Surface Water Advisory is the warning that directly alerts applicators to the risk of pesticides reaching surface waters like streams, rivers, lakes, or ponds. This label note tells you to take specific precautions to prevent runoff, drift, or spills from contaminating those water bodies. It guides actions such as maintaining appropriate buffer zones from water, avoiding application under conditions that promote runoff (heavy rain, irrigation that could carry product to water), using drift-reducing techniques, and following any special handling or timing instructions.

Why this fits best: it explicitly addresses the danger to surface water, which is what the question asks. A Ground Water Advisory would concern underground water sources, not surface water. Practical Treatment is not a warning label, and Use Classification describes where and how the product can be used rather than indicating contamination risk.
