In - situ - treatment of waste water for the prevention of the basis of water contamination.

摘要

An article of manufacture and method for holding and treating water contaminated with one or more water-soluble contaminants to substantially prevent the contaminants from seeping into ground water supplies disposed below a water holding area. The article of manufacture and method include the use of a water-holding material, e.g, a water- swellable clay, such as bentonite, for reducing the permeation of the contaminated water into the soil, and an inground treatment layer containing a material capable of adsorbing, absorbing, ion-exchanging, neturalizing or reacting with one or more water-soluble contaminants within the water for removing a substantial portion of the contaminants from the water so that the portion of the held water that permeates the water-holding layer, will be rendered substantially less contaminated.
