Degradation of Chlorinated Hydrocarbons in Groundwater Passing Through the Treatment Wetland at Wright-Patterson Air Force Base: Analysis of Results Collected During 2001-'06
… are an efficient and cost effective means for chlorinated aliphatic hydrocarbon remediation, and will therefore continue to gain momentum as an accepted treatment by the US EPA (U.S. EPA, 1995; Amarante, 2000; Lien, 2001; WETPOL, 2009). The treatment options for chlorinated aliphatic …

Seepage of Groundwater into the St. Clair River Near Sarnia, Ontario, Canada
… groundwater samples were also analyzed for: chlorinated hydrocarbons, polychlorinated biphenyls, trihalomethanes, EPA Priority Pollutants (extractables), total organic halides (TOX), chloride, and natural isotopes (oxygen-18, deuterium, and tritium). The average observed seepage rate of l. u …

Hydrogeologic Model of a Leachate Plume in an Unconfined Coastal Plain Aquifer and Chemical Transport Mechanisms of Metals and Dense Non-Aqueous Phase Liquids
… was then used to investigate the migration of chlorinated hydrocarbons (CHCs) and metals in unconfmed high porosity sandstone, indicating that migration for both CHCs and metals were caused by advective transport. In addition, the results also indicated that CHCs migrate by the process of …

The Vibrational Spectra of Chlorosubstituted Hydrocarbons
Infrared spectra of saturated and unsaturated chlorinated hydrocarbons have been studied using low temperature techniques, including isolation in an inert matrix. The compounds were selected in relation to problems in the understanding of the properties of poly (vinyl chloride).<br/><br/>The …

Thermochemistry and kinetics in pyrolysis and oxidation reaction of oxygenate chlorocarbons, neopentane, and ortho-xylene
Thermochemical properties of chlorinated alcohols, chlorinated hydroperoxides and corresponding alkoxy, hydroxy alkyl radicals, peroxy and hydroperoxy alkyl radicals are determined by ab initlo and density functional calculations for modeling and optimization of complex chemical processes for …

Characterization of block copolymers and polymer blends by inverse gas chromatography
… values. Mixtures containing ketones, aromatics hydrocarbons, chlorinated hydrocarbons, alcohols and water were studied. With the exception of mixtures containing water and low molecular weight alcohols, a fair to good correlation between theoretical and experimental values was observed. Second, …

Investigations on mobility of carbon colloid supported nanoscale zero-valent iron (nZVI) for groundwater remediation
… Zerovalent iron (ZVI) is highly reactive with chlorinated hydrocarbons (CHCs) and renders them into less harmful substances. Application of nZVI instead of granular ZVI can increase rates of dechlorination of CHCs by orders of magnitude, due to its higher surface area. This approach is still …

Effects of Capping on Biodegradation of Organic Contaminants in Sediments
… of organic contaminants, polycyclic aromatic hydrocarbons (PAHs) and hexachlorobenzene (HCB). Microcosm studies were conducted to investigate the attenuation potential of PAHs and HCB in Anacostia River sediment mixed with BionSoil as a capping material. BionSoil was used because it is rich in …

Untersuchungen zur Elektrochemischen Bodensanierung für die Stoffklasse der hochsiedenden aliphatischen Chlorkohlenwasserstoffe
Die elektrokinetische Bodensanierung nutzt Transporteffekte aus, die entstehen, wenn ein elektrisches Feld an einen Bodenkörper angelegt wird. Die Sanierungsmethode versagt bei immobilen Schadstoffen. Allerdings scheint unter bestimmten Bedingungen ein im Boden induzierter Abbau der Schadstoffe …
