What is a buffer zone between a field and a water body?

• A. A no-spray area or restricted zone to prevent drift or runoff into water bodies.
• B. An area where pesticides are sprayed more heavily.
• C. An area used to store pesticides.
• D. A zone with mandatory PPE.

Answer: (A)

Buffer zones are areas kept as no-spray or restricted zones between a field and a water body to protect water quality. The purpose is to prevent pesticide drift through the air and runoff from reaching streams, rivers, or lakes, which helps protect aquatic life and drinking water sources. This description matches how buffer zones function in practice: they create a safe buffer that reduces the chance pesticides reach water bodies. Other choices describe spraying more heavily, storage, or PPE, which relate to different pesticide practices and don’t address protecting water from drift or runoff. In the real world, the required width of a buffer can vary by product, application method, and local rules, and it may include vegetated strips that help trap chemicals.
