Hazardous Waste Management

William & Mary generates hazardous and non-hazardous waste from maintenance, laboratory and studio activities. As a registered large quantity generator, all chemical waste generated in University laboratories and other facilities must be disposed of in accordance to the guidelines and regulations mandated by the Virginia Department of Environmental Quality (DEQ) and Federal Environmental Protection Agency (EPA).

William & Mary’s Hazardous Waste Management and Pollution Prevention Program details the guidelines to ensure that all hazardous waste is properly and safely managed from generation to disposal. In addition, the program describes practices to reduce the creation of pollutants and wastes at the source through pollution prevention. 


  • Determine if you can reuse or recycle this waste in the laboratory, facility or studio. If so, there is no need to dispose of the material through the W&M Hazardous Waste Program disposal procedures.
  • For unopened or uncontaminated containers in a usable form, attempt to find another user. This will avoid the cost of disposal, and the environmental impact of disposal.
  • Separate solids and liquids. All liquids must be free of solid material and/or sludge to facilitate consolidation, recycling and proper disposal. If solids cannot be separated from liquids, the identification and quantity of the solid component must be listed on the Hazardous Waste Disposal Request Form.
  • Consolidate similar wastes into as few containers as possible.
  • Properly package the waste. Make sure containers are compatible with the material inside, if not transfer to a new container. Containers must be leak free, have a tight cap, and be clean on the outside. Stoppers and corks are not suitable.  Containers should be no more than 90% full to avoid spills.
  • Complete the Hazardous Waste Disposal Form and label all containers with the hazardous waste labels.  Information on the labels must agree with the information on the disposal form.
  • Prepare the waste containers for pick-up and transport by placing in a centralized area within the facility, laboratory, or studio.
  • Contact EH&S to schedule a hazardous waste pickup.
