Citation:
Thorneloe, S., D. Kosson, AND G. Helms. A New Generation of Leaching Tests – The Leaching Environmental Assessment Framework. Presented at Global Waste Management Symposium, Orlando, Fl, June 23 - 25, 2014.
Impact/Purpose:
To present newly released leaching tests that help to provide more accurate source terms for environmental release from disposal or use of waste or industrial by-products.
Description:
Provides an overview of newly released leaching tests that provide a more accurate source term when estimating environmental release of metals and other constituents of potential concern (COPCs). The Leaching Environmental Assessment Framework (LEAF) methods have been (1) developed for inclusion in EPA’s SW-846, (2) validated working with 20 laboratories, and (3) posted on EPA’s SW-846 web site as new methods. This papers provides an overview of the LEAF methods, use in evaluating coal combustion residues, and remaining work to implement LEAF methods
