Leaching Tests<\/h3>\n

The framework recommends a collection of four leaching tests that follow the tiered approach of leach testing as published in literature (Kosson et al., 2002). These tests can be used to develop a characteristic leaching profile of the subject material under equilibrium- and mass transfer-controlled release. Each test is designed to vary a critical release-controlling parameter (e.g., pH, liquid-to-solid ratio, leaching time) to provide leaching data over a broad range of test conditions.<\/p>\n

Preliminary Versions of EPA Methods<\/h3>\n

The U.S. EPA Office of Resource Conservation and Recovery (ORCR)\u00a0and Office of Research & Development (ORD), in collaboration with Vanderbilt University, ARCADIS-US Inc., and leaching experts from around the country, have initiated the interlaboratory validation of a suite of alternative leach testing methods. These tests are under review for inclusion in “Test Methods for Evaluating Solid Waste, Physical\/Chemical Methods” (SW-846).<\/p>\n

Method 1313 Batch Test Preparation in Lab<\/figcaption><\/figure>\n

Leaching characterization\u00a0under LEAF\u00a0consists of testing using one or more of the following four methods:<\/p>\n

    \n
  • Method 1313<\/strong>: Liquid-Solid Partitioning (LSP)\u00a0as a Function of Eluate pH Using a Parallel Batch Extraction Procedure<\/li>\n
  • Method 1314<\/strong>: Liquid-Solid Partitioning (LSP)\u00a0as a Function of Liquid-to-Solid Ratio Using an Up-Flow Percolation\u00a0Column Procedure<\/li>\n
  • Method 1315<\/strong>: Mass Transfer Rates in Monolithic and Compacted Granular Materials Using a Semi-dynamic Tank Leaching Procedure<\/li>\n
  • Method 1316<\/strong>: Liquid-Solid Partitioning (LSP) as a Function of Liquid-to-Solid Ratio\u00a0Using a Parallel Batch Extraction Procedure<\/li>\n<\/ul>\n

    These methods are described in individual pages of this website, along with their projected SW-846 method IDs.\u00a0 Note that the designation as a “preliminary version” does not denote endorsement by the U.S. EPA or SW-846.<\/p>\n","protected":false},"excerpt":{"rendered":"
