What should you do with rinse water after cleaning equipment?

• A. Use it to water crops.
• B. Pour into a storm drain.
• C. Dispose according to label.
• D. Store for later use.

Answer: (C)

Rinse water after cleaning equipment contains pesticide residues, so it must be handled exactly as the label instructs to protect people and the environment. The label will tell you the proper disposal or treatment method, such as collecting the rinse water and disposing of it through approved waste systems or treating it in a designated facility. It should not be released to crops or fields, as spreading residues onto harvests can contaminate food. Pouring it into a storm drain can lead to contamination of waterways, which is typically restricted or prohibited. Storing rinse water for later use is generally not appropriate because the mixture can accumulate residues and degrade in unpredictable ways, unless the label explicitly allows reuse. Following the label ensures safe, compliant handling and environmental protection.
