As a result of their widespread use as solvents, degreasers, and dry cleaning agents, chlorinated aliphatic hydrocarbons (PCE, TCE, DCE, etc.) represent one of the most common and most persistent groups of contaminants found in groundwater. Characteristically, these compounds exist in the form of DNAPLs in the subsurface making efforts at remediation particularly difficult. In-situ bioremediation via direct hydrogen addition has the potential to become a simple and low-cost treatment approach for sites contaminated with chlorinated solvent compounds (PCE, TCE, etc.). Based on the results of recent research, the role of hydrogen as an electron donor is now widely recognized as the key factor governing the dechlorination of chlorinated compounds. Because of hydrogen`s low cost, its ability to be delivered safely and inexpensively in a variety of ways, and its ability to promote rapid dechlorination, direct hydrogen addition represents a potentially superior approach for managing and remediating chlorinated solvent plumes.
