    "1. A measure of the concentration or mass of petroleum hydrocarbon constituents present in a given amount of soil or water. The term \"total\" is a misnomer--few, if any, of the procedures for quantifying hydrocarbons are capable of measuring all fractions of petroleum hydrocarbons present in the sample. Volatile hydrocarbons are usually lost in the process and not quantified, and some non-petroleum hydrocarbons are sometimes included in the analysis.\n\n2.
