ABSTRACT:
A system for sealing leaks in a nonconductive liner of a container of liquid or liquid-solid material. A voltage is impressed between an electrode in the material inside the container and an electrode in conductive material outside the liner. The system provides for a current path between these electrodes through any leaks that may exist in the liner. Solid particles suspended in the liquid in the impoundment accumulate at the leak as a result of electrophoresis, thereby sealing the leak. Although the system is especially useful for impounded waste materials, such as a landfill or surface impoundment, it may be used for many other types of containers.
