TestAmerica Offers In-House Capabilities to Support EPA’s Leaching Environmental Assessment Framework (LEAF) Test Methods


TestAmerica offers in-house capabilities to support the U.S. EPA’s Leaching Environmental Assessment Framework (LEAF) Test Methods.

The LEAF Test Methods represent a change from current leaching assessment approaches. The methods comprise a suite of leaching tests, which include batch, column, and tank tests. These methods are pre-U.S. EPA SW-846 Methods that have not been released as either draft or final SW-846 Methods. They are:

• Method 1313 “Liquid-Solid Partitioning as a Function of Extract pH for Constituents in Solid Materials using a Parallel Batch Extraction Procedure”.
• Method 1314 “Liquid-Solid Partitioning as a Function of Liquid-Solid Ratio for Constituents in Solid Materials using an Up-flow Percolation Column Procedure”.
• Method 1315 “Mass Transfer Rates of Constituents in Monolithic or Compacted Granular Materials using a Semi-dynamic Tank Leaching Procedure”.
• Method 1316 “Liquid-Solid Partitioning as a Function of Liquid-Solid Ratio for Constituents in Solid Materials using a Parallel Batch Extraction Procedure”.

TestAmerica is committed to providing timely and relevant analytical testing services to the nation’s coal-fired electric power fleets, and to firms engaged in the business of beneficially using coal combustion products in commerce. TestAmerica is a member of the Edison Electric Institute, the Utility Solid Waste Activities Group, and the American Coal Ash Association.

“TestAmerica Nashville’s experience, under Mr. Johnny Mitchell and Mr. Michael Dunn in support of EPA’s Inter-laboratory Validation Study of Methods 1313 and 1316, has expanded TestAmerica’s ability to support these techniques. At the Pittsburgh location, under the direction of Mr. Larry Matko, Technical Director, and Mr. Rick Sheets, Soil Scientist, we have an experienced team of chemists, chemical engineer and geochemist, who have led the implementation and commercial offering of all four of these new leaching methods at our facilities to our clients,” adds Rusty Vicinie, General Manager.
