“…The degradation constant X is connected with the half-life of the substance ~-~/2 by Zoeteman et al (1981) calculated half-lifes of different organic compounds from observations in a contaminated plume in the Netherlands: 0.3 year for toluene, xylene, and ethyl-benzene; 0.6 year for C 3 benzenes and naphtalenes; I year for benzene, IA.1-trichloroethane, and dichlorobenzene; and I 0 years for dichloromethane.…”

“…But the volatility of a substance does not appreciably interfere with its concentration in ground-water. Thus the elimination effect of high vapour pressure is overestimated in ground-water (Zoeteman et al 1981 ). Notwithstanding the slow gas release from ground-water into the unsaturated zone, this process may result in increased CO 2 and hydrocarbon contents in the ground air, which allows measuring the extent of the contaminated zone (Albertsen and Matthess 1978).…”

The concentration and migration of contaminants in ground-water is influenced by many geochemical, physical, and biological processes.The mobility of inorganic and organic contaminants in ground-water is controlled by their solubility. The dissolution and precipitation behaviour of many substances can be predicted with help of geochemical models on basis of chemical thermodynamics. The adsorption of contaminants on the surface of solid particles and the desorption of other components into solution cause a retardation of contaminant transport with respect to surrounding groundwater. The empirical distribution coefficient as characteristic measure for this process is specific for the given contaminant and the geochemical environment.Convection and hydrodynamic dispersion control the transport and the mixing processes of contaminated ground-water with natural ground-water. The concentration of the contaminants decreases in time and with transport distance whereas the volume of the contaminated plume increases. The specific properties of immiscible organic fluids, e.g. mineral oil products and chlorinated hydrocarbons, result in lower or higher flow velocities than that of water and in the tendency to form separate impregnation bodies on the water table or at the base of the aquifer. Gas transport is important for the removal of volatile contaminants and decay products. The transport of suspended particles is controlled by filtration processes.Organic compounds are decomposed by autochthonic microorganisms that obtain from these processes carbon and hydrogen for their cell synthesis and energy for their metabolism. The main effect of microbial activity is an acceleration of geochemical processes. The propagation of pathogenic bacteria and viruses in ground-water is controlled by the same general mechanisms as that of the other contaminants. However, the active attachment and mobility of bacteria may improve the effectivity of the specific processes.

“…Howard et al (1991) estimated that the half-life of TCE in groundwater ranges from 10.7 months, on the basis of hydrolysis, to 4.5 years on the basis of anaerobic sediments. In the Netherlands, Zoeteman et al (1981) estimated a half-life of 2.0 years in groundwater. Yeh and Kastenberg (1991) estimated 86 days.…”

“…According to an early work by Zoeteman et al [26], compounds of major concern due to their widespread use, mobility, and persistence in ground waters are hydrocarbons, halogenated hydrocarbons, and ketones. Table 2 lists some of the most frequently detected trace organic contaminants in surface waters that are transferred to the aquifer area.…”
