Because of sewer disposal limits on copper, we dispose any concentration of copper sulfate (or any copper solution) as hazardous waste .

I am curious as to how others may be handling dilute solutions of cupric sulfate.  Do you drain dispose if it is a very low concentration? At what concentration would you consider managing this solution as hazardous waste?
