摘要： Compositions and methods for treating contaminated soil and/or ground water in situ. The compositions and methods comprise stabilized forms of colloidal activated carbon that are used to quickly sorb contaminants. Unlike traditional activated carbon in granular or powder form, the compounds and methods of the present invention are operative to transport particulate activated carbon through a matrix of soil and groundwater upon application by injection, gravity feed, or percolation into soil and groundwater, which in turn decontaminate groundwater in place without the cost or disruption associated with digging the contaminated soil and groundwater out of the ground for on-site purification or disposal at a hazardous waste landfill.

摘要： Compositions and methods for in situ ground water remediation. The compositions comprise a colloidal biomatrix comprised of sorbent particles, such as zeolites, organoclays and activated carbon, dispersed in aqueous solution that are injectable into the permeable zones of an aquifer to be treated. Once deposited into the permeable zones of the aquifer, the groundwater concentrations of contaminants in those zones are depleted, thus increasing the rate of diffusion of contaminants of the less permeable zones. The compositions and methods of the present invention can be used to treat any organic contaminants and provide rapid remediation of contaminated ground water by adsorption and biodegradation of such contaminants.
摘要翻译： 原位地下水补救措施的组成和方法。 组合物包含由吸附剂颗粒如沸石，有机粘土和活性炭组成的胶体生物基质，其分散在可注入待处理的含水层的渗透区域的水溶液中。 一旦沉积在含水层的可渗透区域中，那些区域中的污染物的地下水浓度就会消耗，从而增加渗透性较差区域污染物的扩散速率。 本发明的组合物和方法可用于处理任何有机污染物，并通过吸附和生物降解这些污染物来快速修复受污染的地下水。
