EPA-HQ-OLEM-2017-0210 EPA SW-846 Update VI Phase III: Inorganic LEAF Methods and Guidance Nonrulemaking 2024-06-12T01:17:14Z 0b0000648255c4e7   The Leaching Environmental Assessment Framework (LEAF) is a leaching evaluation system, which consists of four leaching tests (i.e., U.S. EPA Methods 1313, 1314, 1315 and 1316), data management tools, and scenario assessment approaches designed to work individually or to be integrated to provide a description of the release of inorganic constituents of potential concern (COPCs) for a wide range of solid materials. The four LEAF methods evaluate how waste constituent leaching changes with changing environmental conditions. The tests are intended to be more accurate than single point leaching tests by assessing constituent leaching potential under varied conditions. Because the LEAF test methods represent a new approach to evaluating leaching potential, the Agency has developed a guidance document to help potential users understand the tests and how to use them. The guidance will also help users interpret the data generated by these tests and provide examples of how the test data can be used for assessing possible constituent release and provide a source term for groundwater fate and transport models used in risk assessment.   Test Guidelines/Methods ["Leaching", "LEAF", "inorganic", "test method", "leaching potential", "constituent release", "fate and transport", "source term", "risk assessment"]   LEAF for Inorganics     {"displayProperties": [{"name": "generic", "label": "Location", "tooltip": "Agency specific program associated with a docket (regulatory action); equivalents: Bureau, Docket Item Code, Program Area."}, {"name": "abstract", "label": "Description", "tooltip": "Describes an agency's specific regulatory action; equivalents: Abstract, Docket Subject, General Info, Related To, Summary."}, {"name": "shortTitle", "label": "Short Title", "tooltip": "A combination of letters and or numbers assigned to an agency's regulatory action for purposes of brevity."}], "keywords": ["Leaching", "LEAF", "inorganic", "test method", "leaching potential", "constituent release", "fate and transport", "source term", "risk assessment"], "modifyDate": "2024-06-12T01:17:14Z", "dkAbstract": "The Leaching Environmental Assessment Framework (LEAF) is a leaching evaluation system, which consists of four leaching tests (i.e., U.S. EPA Methods 1313, 1314, 1315 and 1316), data management tools, and scenario assessment approaches designed to work individually or to be integrated to provide a description of the release of inorganic constituents of potential concern (COPCs) for a wide range of solid materials.
