The University of Wisconsin‐Madison generates approximately 16,000 gallons of radioactive and non‐radioactive waste solvents per year. This study was conducted to characterize the waste stream and identify managecent options. Water, chloroform, acetone and hexane constitute the primary compounds of the waste stream. Management options include on‐site incineration, shipment and incineration elsewhere, and reclamation. Source separation of chlorinated and non‐chlorinated waste is an easy and effective procedure in facilitating further disposal options.
