After cleanup, spray tank rinsate should be disposed of on the treated area.

• A. In a drainage ditch
• B. On the treated area
• C. In a fast-flowing stream or river
• D. Down a sinkhole

Answer: (B)

Spray tank rinsate is pesticide-containing waste that still has active ingredients, so it must be disposed of exactly as the label directs to prevent harm. The best practice is to dispose it on the treated area because loading the rinsate back onto the target site uses the product as intended and keeps the chemical where it’s supposed to act, rather than releasing it into the environment. Releasing rinsate into a drainage ditch, a fast-flowing stream or river, or a sinkhole would move contaminants off site, risk harming aquatic life and drinking water, and violate safety rules and label directions. Applying the rinsate to the treated area minimizes environmental impact while adhering to proper disposal guidelines.
