Manufactured Gas Plants (MGPs)

What are MGPs?

MGPs operated to provide gas from coal or oil. MGPs were constructed with similar facilities and generated similar wastes using defined manufacturing processes. The gas manufacturing and purification processes produced by-products and residues that may include tars, sludges, and light oils. These residues may contain Polycyclic Aromatic Hydrocarbons (PAHs), petroleum hydrocarbons, benzene, cyanide, metals and phenols. Residues often occur at the same locations at former MGP sites. Typically, soil, ground water, and nearby sediment can be contaminated. The wastes contain a number of known and suspected cancer-causing agents and other potentially hazardous chemicals.
