Current research on the disposal of hazardous wastes

The Solid and Hazardous Waste Research Laboratory is one of six laboratories in the Environmental Protection Agency (EPA), National Environmental Research Center at Cincinnati, Ohio. The laboratory is responsible for research into new and improved systems of solid and hazardous waste management, development of technology, determination of environmental effects, and collection of data necessary for the establishment of processing and disposal guidelines. In the past, the laboratory concentrated on problems associated with municipal solid waste; but recently the emphasis has shifted, and present efforts are directed primarily toward the problem of industrial hazardous waste disposal on land. Under the solid waste program, investigations were initiated on the migration of municipal landfill leachate and leachate containment with synthetic liners. These studies have been underway for more than a year, but they will not be discussed here because of the present emphasis on industrial hazardous waste problems. Although none of our research projects is concerned specifically with the disposal of residues and sorbants generated during cleanup of hazardous material spills, much of the forthcoming information will be applicable to spill-cleanup problems. The extramural projects and program areas described here involve many activities that could be useful in spill problems.
