This method is one of four Leaching Environmental Assessment Framework (LEAF) methods. It is designed to provide aqueous extracts representing the liquid/solid partitioning (LSP) curve as a function of pH for inorganic constituents, semi-volatile organic constituents, and non-volatile organic constituents in solid materials.
More information about the LEAF, including a detailed "How-To" Guide, can be found on the LEAF web page.
