    Abstract: Composite particles contain a natural stone or aggregate core and a coating of two or more sorbent layers collectively containing at least two distinct kinds of sorbent materials effective for sorbing two distinct contaminants. One or both sorbent layers may be mixed with a water-absorbent, swellable clay that, upon contact with water, causes spalling or disintegration of the coating layer to release the sorptive material into a body of water such as a pond, ditch, stream, or riverbed. Additional swellable or protective layers may also be present. The composite particles are deployed into a pond, ditch, river, or streambed where the core of natural stone remains in the riverbed. The sorptive materials of the two different sorbent layers sorb and fix a wide range of contaminants, including both the heavy and light-weight hydrocarbons, from the water, and settle as a fine sediment. The sediment with sorbed contaminants is then removed by means such as hydraulic collectors or dredging.

    Abstract: A membrane 10 is a geomembrane 10, which takes the form of a non-conductive sheet 11. A conductive layer 13 is printed on to the sheet 11, in this instance in a geometric pattern of a rectangular grid. The lines of the grid 13 are conductive and connected to each other, with non-conductive gaps 15 disposed between the grid lines. Accordingly, a conductive linear network is formed, which has the requisite conductivity for leak detection.
