After collecting rinsate from triple rinsing pesticide containers, is it permissible to pour the rinsate down the floor drain?

• A. No, it is not permitted.
• B. Yes, it is permissible.
• C. Only if diluted.
• D. Only if the drain leads to a treatment plant.

Answer: (B)

Disposing of rinsate is guided by the product label and local waste-water rules. After triple rinsing, the rinse water is basically washwater that may still contain small amounts of the pesticide. Pouring this rinsate down a floor drain is allowed in many cases because the water goes into the building’s sanitary sewer and is treated at a wastewater facility, where the residues are diluted and treated before discharge. The key is to follow the label directions and any local regulations; if the label or local rules prohibit sewer disposal, or the drain doesn’t connect to an approved treatment system, then this disposal method would not be allowed.
