Which statement describes the disposal of rinse water after rinsing the measuring container?

• A. Pour the rinse water into a spray tank.
• B. Pour the rinse water down the drain.
• C. Dump onto the ground.
• D. Store indefinitely.

Answer: (A)

Rinsate disposal is treated as part of the spray application. The rinse water still contains pesticide residues, so it should be returned to the spray tank rather than discarded. This keeps all remaining product in use and prevents environmental contamination. Pouring rinse water down the drain can introduce pesticides into wastewater systems; dumping onto the ground can contaminate soil and water; storing indefinitely creates a separate hazardous waste that must be managed later. Therefore, pouring the rinse water into the spray tank is the proper practice.
