    Groundwater pollution is imminent in most developing countries as a result of increased anthropogenic activities apart from possible natural pollutants. This study reviewed groundwater pollution and discussed possible remediation measures. Sources of pollution can be categorized into two major types: point source pollution and non-point source by: 1.

    The potential for in situ biodegradation of tert-butyl alcohol (TBA) by creation of aerobic conditions in the subsurface with recirculating well pairs was investigated in two field studies conducted at Vandenberg Air Force Base (VAFB).In the first experiment, a single recirculating well pair with bromide tracer and oxygen amendment successfully delivered oxygen to the subsurface for 42 by: 5. Sufficient levels of fermentable organic substrates are present to support microbial growth and contaminant biodegradation. The aquifer pH is appropriate for microbial growth and contaminant biodegradation. Critical microorganisms are present in sufficient numbers with the required genetic capability to degrade the pollutants.

The specific objectives of the field study are: 1. To demonstrate whether the pro- posed method of promoting the enzymatic decomposition of TCE and related compounds is effective under controlled experiments per- formed in-situ, in an aquifer representing conditions typical of ground water environments; 2.

Careful site characterization and implementation of quantitative monitoring methods are prerequisites for a convincing evaluation of enhanced biostimulation for aquifer restoration.

This situation is intensified for in situ remediation technologies of any type, because frequently the amount, location, and type of contamination are unknown. Microbial Biodegradation and Bioremediation brings together experts in relevant fields to describe the successful application of microbes and their derivatives for bioremediation of potentially toxic and relatively novel compounds.
