What does SW-846 mean?
Test Methods for Evaluating Solid Waste
The Test Methods for Evaluating Solid Waste: Physical/Chemical Methods Compendium, also known as SW-846 or the Compendium, is EPA’s official collection of methods for use in complying with the Resource Conservation and Recovery Act (RCRA) regulations.
How do you cite SW-846?
If you want a separate reference for each method, use this format: Method xxxxx, Revision x, Month Year, Final Update x to the Third Edition of the Test Methods for Evaluating Solid Waste, Physical/Chemical Methods, EPA publication SW‐846.
What is EPA 3050b?
This document is included in Selected Analytical Methods for Environmental Remediation and Recovery (SAM).
What is sw846?
SW-846 means the laboratory analytical guidance document published by the United States Environmental Protection Agency, titled Test Methods for Evaluating Solid Wastes, Physical/Chemical Methods. This guidance consists of three main parts: chapters, methods and supporting documents and is the EPA SW-846 Compendium.
What does TCLP test for?
TCLP or Toxicity Characteristic Leaching Procedure is a chemical analysis process used to determine whether there are hazardous elements present in a waste. The test involves a simulation of leaching through a landfill and can provide a rating that can prove if the waste is dangerous to the environment or not.
What is acid digestion method?
Acid digestion methods are generally used for the dissolution of herbal product samples prior to elemental analysis (Duyusen and Görkem 2011). Nitric acid is often utilized for this purpose as an oxidant reagent either individually or mixed with other digestion reagents such as acids and/or hydrogen peroxide.
What is RCRA testing?
What tests can be used to determine whether a waste exhibits the Resource Conservation and Recovery Act (RCRA) characteristic of toxicity? In 1990, EPA replaced the extraction procedure test for determining whether wastes exhibit the toxicity characteristic with the toxicity characteristic leaching procedure (TCLP).
What is a priority pollutant for which the EPA has published an analytical test method?
The Priority Pollutants are a set of chemical pollutants EPA regulates, and for which EPA has published analytical test methods. The Priority Pollutant List makes the list of toxic pollutants more usable, in a practical way, for the purposes assigned to EPA by the Clean Water Act.
What EPA method is TCLP?
The Toxicity Characteristic Leaching Procedure (TCLP), which is used for determining whether a solid waste is a hazardous waste by exhibiting the characteristic of toxicity, is Method 1311. You can download a copy of Method 1311 from the EPA website. SW-846 is also available on-line at no cost from the EPA Website.
How is TCLP performed?
During the TCLP procedure, the solid test sample is diluted with extraction fluid that is 20 times the weight of the sample. The total concentration results are then divided by 20 and compared to the TCLP regulatory limits.
What are the test methods for solid waste?
In support of RCRA, EPA developed test methods for the analysis of various environmental media. These test methods can be found in the EPA publication, Test Methods for Evaluating Solid Waste: Physical/Chemical Methods, also known as SW-846.
What is the sw-846 acid digestion test method?
Contact Us SW-846 Test Method 3050B: Acid Digestion of Sediments, Sludges, and Soils This document outlines Method 3050B, which provides two separate digestion procedures for sediments, sludges, and soils.
When did the EPA issue the sw-846 test?
SW-846 is a multi-volume document that changes over time as new information and data are developed. It has been issued by EPA since 1980 and is currently in its third edition.
What do you need to know about sw-846?
SW-846 functions primarily as a guidance document setting forth acceptable, although not required, methods for the regulated and regulatory communities to use in responding to RCRA-related sampling and analysis requirements. SW-846 is a multi-volume document that changes over time as new information and data are developed.
