In one application for remediating sediments, employing a geocomposite sheet eliminates the need for a thick cap or removal and subsequent ex situ treatment of the sediment. A geocomposite with at least one layer of reactive material is placed over the area to be remediated. A layer of available surcharge materials such as sand, gravel, or riprap covers the geocomposite. The weight of the surcharge materials causes pore water to flow from the sediment through the reactive layer or layers of the geocomposite. Contaminants may be trapped in this reactive layer or layers. A top or bottom layer, or both a top and bottom layer, may be provided to inhibit incursion from outside the sediment layer, while permitting appropriate flow direction of pore water into the reactive layer or layers.

A system and method for providing a partial level of saturation to a mass of sand, through generation of gas bubbles, as a way to prevent liquefaction during earthquakes. The system includes a solution that is operable to generate gas bubbles and a solution generator that prepares the solution. A conduit delivers the solution to the sand, so that the solution generates the gas bubbles during and after being delivered to the sand. A probe may be used to determine whether the sand is susceptible to liquefaction before the solution is delivered and to assess a change in degree of partial saturation after the solution has been delivered.

Methods and apparatuses to transform contaminants in water by electrolytic processes are described. In some embodiments, the apparatuses and electrolytic processes couple an anode comprising iron and a high specific surface area cathode. Methods and apparatuses described herein provide advantages over conventional apparatuses and methods such as, for example, cost savings, efficiency, environmentally benign impact and versality for a variety contaminants.

Disclosed is a method of removal of an organic pollutant from an aqueous solution, comprising: a) contacting the solution with an anode and a cathode comprising a carbon material; b) applying electrical current to the anode, thereby generating reactive oxygen species; b) oxidizing the organic pollutant with the reactive oxygen species; and c) regenerating the carbon material. Also disclosed is a method of producing reactive oxygen species, comprising: a) flowing an aqeous solution through a reactor comprising at least one cathode and at least one anode; b) applying electrical current to the at least one anode; and c) collecting a product solution comprising reactive oxygen species.
