“…In situ microbial bioremediation of aquifers contaminated with volatile organic compounds has received increasing attention as an alternative to pumpand-treat (Wilson et ah, 1986;Lee et al, 1988;Baker & Herson, 1991). It has the potential advantages that many common organic contaminants can be biodegraded to innocuous compounds by naturally occurring microorganisms, that it is a contaminant-destructive as opposed to a contaminant-relocative process, and that it is carried out in situ, obviating the need for disposal of the treated groundwater.…”

“…The usual approach to in situ aquifer bioremediation is to pump a suite of nutrients into the subsurface to stimulate the growth of indigenous bacterial populations (Wilson et al, 1986;Lee et al, 1988;Flathman et al, 1989;Roberts étal., 1990;Semprini étal., 1990;Baker & Herson, 1991). Ideally, the resulting increase in biomass causes the desired biodégradation at an acceptable rate.…”

An in situ microbial filter technology is being tested and developed for remediating migrating subsurface plumes contaminated with low concentrations of trichloroethylene (TCE). The current focus is the establishment of a replenishable bioactive zone (catalytic filter) along expanding plume boundaries by the injection of a representative methanotrophic bacterium, Methylosinus trichosporium OB3b. This microbial filter strategy has been successfully demonstrated using emplaced, attached resting cells (no methane additions) in a 1.1 m flow-through test bed loaded with water-saturated sand. Two separate 24 h pulses of TCE (109 ppb and 85 ppb), one week apart, were pumped through the system at a flow velocity of 15 mm h" 1 ; no TCE ( < 0.5 ppb) was detected on the downstream side of the microbial filter. Subsequent excavation of the wet sand confirmed the existence of a TCE-bioactive zone 21 days after it had been created. An enhanced longevity of the cellular, soluble-form methane monooxygenase produced by this methanotroph is a result of the laboratory bioreactor culturing conditions. Additional experiments with cells in sealed vials and emplaced in the 1.1 m test bed yielded a high resting-cell finite TCE biotransformation capacity of about 0.25 mg per mg of bacteria; this is suitable for a planned sand-filled trench field demonstration at a Lawrence Livermore National Laboratory site.

“…From a practical standpoint, it appears that it is unnecessary to add hydrocarbon degrading microbes to such contaminated sites, but rather a need to optimize biological degratation by monitoring and modifying oxygen, nutrients, and moisture. (For summaries of work on stimulating biodegradion of petroleum in soils, see Lee et al 1988;Morgan and Watkinson, 1990. ) …”

“…More than three decades of research has produced numerous laboratory and field studies have shown that microorganisms indigenous to the subsurface environment can degrade a variety of hydrocarbons, including components of gasoline, kerosene, diesel, and jet fuel (e.g., Jamison et al, 1975;Atlas, 1981Atlas, , 1984Atlas, , and 1988Young, 1984;Bartha, 1986;Wilson et al, 1986 andBarker et al, 1987;Baedecker et al, 1988;Lee, 1988;Chiang et al, 1989;Cozzarelli et al, 1990;Leahy and Colewell, 1990;Alvarez and Vogel, 1991;Evans et al, 1991a and1991b;Thierrin et al, 1992;Malone et al, 1993;Davis et al, 1994a and1994b;Lovley et al, 1995). In fact, almost all petroleum hydrocarbons are biodegradable.…”
