What is the primary purpose of a buffer zone around lakes, streams, or wells when applying aquatic pesticides?

• A. To protect water quality and non-target organisms by reducing off-site movement and exposure.
• B. To increase pesticide efficacy near water.
• C. To reduce the need for PPE.
• D. To shorten application time.

Answer: (A)

Buffer zones around lakes, streams, and wells are put in place to keep pesticides from moving off the treated area and entering water or affecting non-target organisms. By creating space between where you apply the product and the water, these zones reduce the chances of drift, runoff, or leaching reaching surface or groundwater. This helps protect water quality and aquatic life, as well as drinking-water sources. The buffer does not make applications more effective near water, nor does it reduce the need for PPE or shorten the time needed for spraying. Follow the buffer distances specified on the label to minimize environmental impact and comply with regulations.
