TeachMeFinance.com - explain Total Petroleum Hydrocarbons (TPH) Total Petroleum Hydrocarbons (TPH) -- Measure of the concentration or mass of petroleum hydrocarbon constituents present in a given amount of soil or water. The word "total" is a misnomer--few, if any, of the procedures for quantifying hydrocarbons can measure all of them in a given sample. Volatile ones are usually lost in the process and not quantified and non-petroleum hydrocarbons sometimes appear in the analysis.
