Development and Use of the Leaching Environmental Assessment Framework in the United States
Citation:
Thorneloe, S. Development and Use of the Leaching Environmental Assessment Framework in the United States. Presented at 2nd Symposium of International Waste Working Group Asian Regional Branch, Shanghai, CHINA, April 10 - 16, 2015.
Impact/Purpose:
To provide an overview of new leaching methods that evaluate equilibrium and mass transfer for inorganics and other constituents for disposal, use, delisting, and long-term performance of concrete and cementitious materials.
Description:
The purpose of this presentation is to provide technical expertise at an upcoming workshop to discuss the use of EPA’s new leaching tests at a workshop on “Risk Informed Approaches and Regulations for Reclamation, Treatment, Use orDisposal”. This presentation has been requested by Professsor Pinjing at Tongji University in Shanghai, China. The new leaching methods provide the source term characterization for management decisions of industrial wastes and byproducts, construction and demolition waste, energy residuals and restoration of contaminated sites. Globally, the environmental behavior of constituents of potential concern from use of indutrial by-products and the goal of protection of human health and environmental resources is common goal for China, the U.S., and European researchers to inform policy decisions. Whenever practical and environmentally safe, it is desirable to achieve beneficial use of industrial and energy byproducts andreuse of formerly contaminated sites. The presentation will be to communicate EPA’s Leaching Environmental Assessment Framework (LEAF) to provide source characterization data for the range of materials and environmental conditions thatmaterials or wastes may encounter during disposal or use.
