SELF-PURIFICATION ABILITY OF WATER SYSTEMS. When the water in the physical environment becomes polluted, it is purified after a certain period. We call this the self-purification ability of water. A long time ago, this process was summarized in the Slovenian proverb saying that, "the water is cleansed, when it runs over seven stones".
