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. SW-846 is organized into chapters providing guidance on how to use the methods and groups of methods, called “series”, which are organized by topic. The methods and chapters change over time as updates are published to keep up with evolving analytical and measurement needs.
