Aqueous Solutions

Non-Hazardous Aqueous Waste
Only non-hazardous aqueous waste can be be washed down the sink.

Identification
To determine if a solvent is hazardous, consult its Material Safety Data Sheet (MSDA) at the MSDS folder next to the fume hood or at ChemWatch Gold FFX

If you are still unsure if a solvent is aqueous or non-aqueous, simply put a drop of water in the solvent. If the drop dissolves, the solvent is aqueous. If dissolution does not occur, the solvent is non-aqueous.

Disposal
Once a solvent's nature is determined to be aqueous, dispose of the solvent in the aqueous waste container next to the sink in the wet labs. Use of a funnel will assist with preventing accidental spillage into this container. Use of a tray underneath the waste container will assist with cleaning, if accidental spillage does occur
