Abstract
This research addresses the role of volatile organic compounds (VOC) as indicators of groundwater pollution by hazardous wastes. These compounds consist primarily of hydrocarbons, e.g., benzene, and chlorinated hydrocarbons, e.g., trichloroethylene, that are neutral, only sparingly soluble in water, and readily evaporated from water. Because of their lack of chemical reactivity under mild conditions and their ready volatilization, VOC are particularly difficult to determine in groundwater, and emphasis has been placed on that aspect of the research. Chromatography, in some cases combined with mass spectrometry, has been used as the analytical method of choice. Attention has been given to sample preservation and consideration to the possibility of on-site monitoring.
