What safety measures should be taken when applying pesticides near water bodies?

Using appropriate buffer zones is a critical safety measure when applying pesticides near water bodies. Buffer zones are areas where pesticide application is restricted or adjusted to minimize the risk of pesticide runoff into adjacent water sources. Establishing these zones helps protect aquatic ecosystems, wildlife, and drinking water supplies from chemical contamination. This practice is essential for adhering to environmental regulations and maintaining ecological balance.

Buffer zones can vary based on the type of pesticide used, its toxicity levels, and the specific characteristics of the water body. By implementing these zones, applicators can significantly reduce the likelihood of harmful substances entering waterways, thus safeguarding aquatic habitats and public health.

While the other choices also propose safety measures—such as using personal protective equipment, applying during calm weather, and limiting applications to early morning hours—they don't directly address the environmental impact on water bodies as specifically as establishing buffer zones does. Each of these practices contributes to overall safety but may not provide the same level of protection against water contamination as buffer zones.
