This report presents the results of an interlaboratory study of three methods--Diesel-Range Organics, Gasoline-Range Organics, and Petroleum Hydrocarbons--used to analyze hydrocarbons in soils. Each method is validated, its performance judged from measurements of accuracy and precision, and practical qualification levels (PQLs) are estimated for each method. The full text of each method is included in the report.
