Environmental Chemistry and Kinetics of Biotransformation of Chlorinated OrganicCompounds in Ground Water

摘要

The rates of attenuation of chlorinated solvents and their less chlorinateddaughter products in ground water are slow as humans experience time. If concentrations of chlorinated organic compounds near the source are in the range of 10,000 to 100,000 micrograms/liter, then a residence time in the plume on the order of a decade or more will be required to bring initial concentrations to current MCLs for drinking water. Biodegradation as a component of natural attenuation can be protective of ground water quality in those circumstances where the time of travel of a plume to a receptor is long. In many cases, it will be necessary to supplement the benefit of natural attenuation with some sort of source control or plume management.
