EPA’s SW-846 Compendium consists of three main parts—chapters, methods and supporting documents. Most methods are intended as guidance, with the exception of method defined parameters (MDPs) that are mandated by the RCRA regulations. The chapters provide insight on how to successfully use the test methods. The supporting documents provide insight into the organization and history of the SW-846 document. In particular, the Table of Contents and Methods Status Table are used frequently.
