How should rinsate from spray tanks be disposed of?

• A. Treat as pesticide waste and apply to an authorized site or dispose at a permitted facility
• B. Dump into the nearest sewer
• C. Pour onto the ground anywhere
• D. Mix with drinking water

Answer: (A)

Rinsate from spray tanks contains pesticide residues, so it must be treated as pesticide waste. The best disposal is to send it to an authorized pesticide-waste site or a facility permitted to handle such waste, ensuring proper treatment or containment and compliance with regulations. This protects water quality, soil, and people from exposure and aligns with safety rules and label instructions. Dumping into a sewer can introduce contaminants into wastewater treatment systems and waterways; pouring on the ground can contaminate soil and groundwater; mixing with drinking water creates a direct health risk.
