BIOREMEDIATION OF FORMER MANUFACTURED GAS PLANT SITES Vipul J. Srivastava, Assistant Director John J. Kilbane, Environmental Microbiologist Robert L. Kelley, Microbial Physiologist W.

Linz, Manager Land and Water Quality Research Gas Research Institute Chicago, Illinois 60631 INTRODUCTION Manufactured Gas Plant Wastes Manufactured gas plants, also referred to as town gas plants, produced large quantities of tar and related by-products. Although there are some similarities among these sites, the sites often vary significantly in the specific types and quantities of wastes present, depending upon the types of processes used (coal, water, or oil gas) and the era in which the plant was operational. Polynuclear aromatic hydrocarbons (PAH's) are components of all kinds of tars, and tars are a by-product of all of these plants. The physical and chemical characteristics of these tars vary, however, according to the process employed.1,2 Oxide wastes from purifier boxes may contain ferrocyanide and varying amounts of arsenic, chromium, copper, lead, nickel, and zinc (all of which appear on the Environmental Protection Agency priority pollutants list). Lamp black, clinker, cinders, and ash may also be present. Many of these town gas plants were located near waterways to provide access to the large quantities of coal necessary for their processes. Consequently, aromatic hydrocarbon contamination of streams and rivers has been traced back to some town gas sites.2 Town gas plant wastes can be categorized by five major types: • Free tars, oils, and lamp black • Coal tar-contaminated soils • Coal tar/oil-contaminated waters • Purifier box (or spent oxide) wastes • Mixed wastes and fills. The coal tar (predominantly PAH)-contaminated soils represent the largest waste type at most of the sites. Depending on the site location, problems associated with contaminated waters could also be one of the major problems associated with town gas plant wastes. Therefore, the current focus of the work at IGT is to develop biological techniques to efficiently treat contaminated soils and waters. BIODEGRADATION STUDIES AT IGT There are several techniques by which a contaminated site can be cleaned onsite: chemical fixation, soil washing, thermal treatment, and biodegradation.
