  "definition": "1. A U.S. EPA method (418.1) for measuring petroleum hydrocarbons in samples of soil or water. Hydrocarbons are extracted from the sample using a chlorofluorocarbon solvent (typically Freon-113) and quantified by infrared spectrophotometry. The method specifies that the extract be passed through silica gel to remove the non-petroleum fraction of the hydrocarbons. The comparable SW-846 method is 8440 which uses perchlorethane (PCE) as an IR solvent instead of Freon-113.\n\n2. an EPA method (418.1) for measuring total petroleum hydrocarbons in samples of soil or water.
