A system and method is disclosed for treating water to remove suspended solids, disinfect for bacteria and viruses and remove color, taste and odor to produce a potable water. A bactericide is introduced which is relatively stable and long term. The system and method introduces the bactericide to the water in an amount sufficient to kill the bacteria and inactivate viruses, The bactericide is maintained in the water at least for a time period sufficient to kill the bacteria in the water, and, until the water is desired to be consumed at which time the water may be passed through an ion exchange. In this way, there is a decreased likelihood that the water will become recontaminated with the same bacteria and/or viruses before the water is desired to be used. In one embodiment, the bactericide comprises metal ions, such as silver ions and/or copper and zinc ions. In order to introduce the metal ions into the water, the system may comprise an electrode having about 70 percent to 90 percent copper, about 5 percent to 15 percent silver and about 5 percent to 15 percent zinc. Prior to the introduction of the bacteriacide, the water may be treated by passing the water through diatomaceous earth to remove contaminants from the water and/or passing the water through an initial disinfection stage.
