Ruth Ann,

 

This will depend on locale. I know that due to local regulations, our students/researchers must collect the first three rinses as hazardous waste. That said, our local regulations are some of the strictest in the country, so I imagine that the regulatory burden will be significantly less for you.

 

Sincerely,

Hi,

 

When students rinse glassware with water, after making a reasonable effort to remove excess chemicals, can the rinse water legally go down the drain?  Thank you!
