You are involved in the remediation of an aquifer that has been contaminated with 2-methylnaphthalene. Similar to the toluene case discussed in Illustrative Example 14.2, the aquifer is flushed with air-saturated water that is pumped into the ground at one place and withdrawn nearby. Calculate how much water is at least required to supply sufficient oxygen for the microbial mineralization of 1 kg of 2-methyl-naphthalene assuming that the water contains 10 mg 02 L 1.

Pretreatment of contaminants with various reagents to produce degradates more amenable to microbial mineralization (Leeson et al, 1993) and treatment of soil slurries with microbial enzymes (Nelson and Jones, 1994) have been successful in remediation. 

Dibenzothiophenes. Because of its commercial availability, dibenzothiophene is the most extensively used compound in studies of organosulfur metabolism. It has been used as a model compound in the studies of petroleum and coal biodesulfurization. These topics have been reviewed by Foght, J.M. Fedorak, P.M. Gray, M.R. Westlake, D.W.S.

The source of phosphorus for incorporation into CFA in the early diagenetic regime is solid-phase phosphorus liberated either by microbial mineralization of organic matter, or by release of phosphorus associated with iron oxyhydroxides upon reduction of the iron oxyhydroxide substrate once it is transported into suboxic or anoxic zones within sediments. Examination of SEDEX-generated phosphorus profiles from a number of studies show roughly mirror-image profiles of the...

A series of related experiments investigated nonionic surfactant sorption onto soil, mechanisms of nonionic surfactant solubilization of polycyclic aromatic hydrocarbon (PAH) compounds from soil, and microbial mineralization of phenanthrene in soil-aqueous systems with nonionic surfactants. Surfactant solubilization of PAH from soil at equilibrium can be characterized with a physicochemical model by using parameters obtained from independent tests in aqueous and soil-aqueous systems. The microbial degradation of phenanthrene in soil-aqueous systems is inhibited by addition of alkyl ethoxylate, alkylphenyl ethoxylate, or sorbitan- (Tween-) type nonionic surfactants at doses that result in micellar solubilization of phenanthrene from soil. Available data suggest that the inhibitory effect on phenanthrene biodegradation is reversible and not a specific, toxic effect.
