Waste Characterization

Landfill Waste Characterization At Eurofins TestAmerica

Eurofins TestAmerica provides clients in the Waste Management Sector with numerous options for waste characterization and classification per Resource Conservation and Recovery Act (RCRA) guidelines contained in 40 CFR part 261.  Working with a trusted and well qualified laboratory for waste testing is critical to ensure you receive results of the highest quality when completing waste characterization activities.

Under RCRA, EPA developed standards for the disposal of potentially hazardous wastes in the United States.  In order for wastes to be accepted at the majority of municipal landfills throughout the country, it must be demonstrated that the material being disposed of meets EPA’s definitions of a non-hazardous waste.  To achieve this, several testing protocols have been developed:

Toxicity Characterization Leaching Procedure (TCLP), Method SW-846 1311

The TCLP leaching procedure was designed to determine the mobility of both organic and inorganic analytes present in various types of waste.  The leaching process simulates the conditions present in a landfill as liquids percolate through the solid waste.  In the laboratory, solid wastes are placed in a sealed vessel with leaching fluid.  The vessel is then rotated, or tumbled, for approximately 18 hours and the resulting leachate is analyzed.  The TCLP method includes a specific list of organic and inorganic compounds, and includes regulatory levels for each compound.  Federal regulation for the use of TCLP can be found in 40 CFR 261.24

Synthetic Precipitation Leaching Procedure (SPLP), Method SW-846 1312

The SPLP analysis was also designed to determine the mobility of organic and inorganic analytes.  However, in contrast to TCLP, this method mimics the leaching of contaminants that are exposed to acidic rain conditions.  The analytical procedure is similar to that of TCLP, but with the introduction of a different leaching fluid.

Soluble Threshold Limit Concentration (STLC), CCR T22:66261.24

The STLC leaching procedure is similar to TCLP and is utilized in California per Title 22 of the California Code of Regulations.
