Hazardous Wastes at UMass Dartmouth are regulated according to regulations of the Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection (DEP). In order to decide whether you have a hazardous waste, you must determine whether your waste has certain characteristics or appears on one of several lists. If it does, then you must manage it according to requirements identified in our Lab Waste Guide. If waste you have does not meet this criteria and is not a hazardous waste, please confirm with Environmental Health and Safety whether it is appropriate to dispose of your waste down the sink or regular trash. Although some waste you generate may not be a hazardous waste, it still may be necessary to manage it this way to prevent adverse effects to health, safety or the environment.
