The following document provides information on the procedure used to quantify low concentrations of oil and grease in soil, sediments, sludges, and other solid materials amenable to chemical drying and solvent extraction.

This method is an SW-846 Method-Defined Parameter (MDP), meaning that it may not be modified when used for Resource Conservation and Recovery Act (RCRA) testing. For more information, see the Methods Innovation Rule page.
