Hello Laurie,
My experience is that it is never okay to dump chemicals into the sink. I work in a production lab and we currently put all hplc waste in a grounded 55 gallon drums and an approved waste company pick it up to dispose it properly. By law we don't have the authority to treat wastes like waste companies do. I hope this helps.

The student working on the project has used this procedure at another institution and said they dumped the waste solvent down the drain. Really? I thought this would still have some characteristic hazard. Does anyone else have experience with this mixture, and how do you dispose of it properly?
