This method is one of four Leaching Environmental Assessment Framework (LEAF) methods. It is designed to provide the mass transfer rates (release rates) of inorganic analytes contained in a monolithic or compacted granular material, under diffusion-controlled release conditions, as a function of leaching time.

More information about the LEAF, including a detailed "How-To" Guide, can be found on the LEAF web page.
