Technical, regulatory and societal aspects of Hazardous and Solid Waste Management are addressed. Topics related to Hazardous Waste include: (1) evolution of current laws dealing with hazardous waste disposal and cleanup; (2) investigation and remediation contaminated sites; and (3) environmental fate and transport of hazardous chemicals. Solid Waste topics include (1) social, economic and political forces that influence the waste management industry; (2) current laws governing solid waste management; and (3) emerging concepts, including Integrated Solid Waste Management, Materials Management, and Life Cycle Analysis. For both focus areas, a strong emphasis is placed on communication of technical issues to the public.
