Title: Manufactured gas plant sites: Characterization of wastes and IGT`s innovative remediation alternatives

Manufactured gas plants (MGP)--often referred to as town gas plants--have existed in many parts of the world, including the United States, during the nineteenth and twentieth centuries. Consequently, many of these plants disposed of process wastes and less valuable by-products onsite, contaminated with coal-tar wastes, light oils, naphthalene, etc. Polynuclear aromatic hydrocarbons (PAHs) are components of coal-tar wastes and other wastes that remain at many of these town gas sites. PAH- containing soils, as a result, represent the largest waste type at most MGP sites. Also, certain PAHs are recognized today as being potential animal and/or human carcinogens and, as such, represent an environmental hazard. The Institute of Gas Technology (IGT) has developed and/or evaluated several techniques/processes to improve the biodegradation of PAHs present at MGP sites. As a result of extensive studies, IGT has successfully developed and demonstrated an integrated Chemical/Biological Treatment (CBT) process that is capable of enhancing the rate as well as the extent of PAH degradation. This process combines two complementary as well as powerful remedial techniques: (1) chemical pretreatment using Fenton`s reagent and (2) a biological system using native aerobic microorganisms. This paper presents the general characteristics of MGP sites and wastes and the innovativemore » IGT processes at various stages of development and demonstration. This paper also discusses the IGT/GRI treatability protocol that can be used to determine the potential of bioremediation for any MGP site soil within a 2 to 3-month period.« less
