Abstract: A system and method for the enhancement or fortification of a potable fluid. The system is adapted to fit on existing supplies of potable fluids, such as faucets, to permit the selective introduction of beneficiating materials into the liquid supply. The system includes interchangeable, replaceable cartridges. In one aspect of the invention, the system introduces a constant concentration of beneficiating material into the water supply. In another aspect, the system has the ability to permit discrete or continuously variable concentrations of the beneficiating material. The system may also include a water filtration device that may be operated either independently or cooperatively with the system.
