Good drinking water quality is essential to the health and well-being of all people. The most serious water pollutants in terms of human health worldwide are pathogenic organisms. Oligodynamic action is the ability of small amounts of heavy metals to exert a lethal effect on bacterial cells. Definite metals and metal compounds confer in minute quantity of water solutions the ability to change and finally kill cells of microorganisms in a characteristic way. Many metallic elements have been observed to inhibit the growth of bacteria and to inactivate enzymes. Practical application of such activity of metals has been made in the purification of water and in the preservation of tomato juice, cider and hides. This antimicrobial effect is shown by metals such as mercury, silver, copper, lead, zinc, gold, aluminum and other metals, and the concentration of the metal needed for this antimicrobial effect is extremely small. The exact mechanism of this action is still unknown but some data suggest that the metal ions denature protein of the target cells by binding to reactive groups resulting in their precipitation and inactivation. The high affinity of cellular proteins for the metallic ions results in the death of the cells due to cumulative effects of the ion within the cells. The main focus of this study is the promotion of use of oligodynamic metals such as silver and copper, to control the pathogens in drinking water.
