This method is one of four Leaching Environmental Assessment Framework (LEAF) methods. It is designed to provide the liquid-solid partitioning (LSP) of inorganic and non-volatile organic constituents at the natural pH of the solid material as a function of liquid-to-solid ratio (L/S) under conditions that approach liquidsolid chemical equilibrium.
More information about the LEAF, including a detailed "How-To" Guide, can be found on the LEAF web page.
