Description:

The development of effective in situ and on-site bioremediation technologies can facilitate the cleanup of chemically-contaminated soil sites. Knowledge of biodegradation kinetics and bioavailability of organic pollutants can facilitate decisions on the efficacy of in situ and on-site bioremediation of contaminated soils and determine the attainable treatment end-points. Two kinds of compounds have been studied: (1) phenol and alkyl phenols, which represent hydrophilic compounds, exhibiting high water solubility and moderate to low soil partitioning; and (2) polycyclic aromatic hydrocarbons which are hydrophobic compounds with low water solubility and exhibit significant partitioning in soil organic carbon. Representative data are given for phenol and naphthalene. The results provide support for a systematic multi-level protocol using soil slurry, wafer and porous tube or column reactors to determine the biokinetic parameters for toxic organic pollutants. Insights into bioremediation rates of soil contaminants in compact soil systems can be attained using the protocol.
