  2. Organic matter - Wikipedia

    en.wikipedia.org/wiki/Organic_matter

    In water, organic matter can still bind to metal ions and minerals. The purification process does not necessarily stop these bound molecules but does not cause harm to any humans, animals, or plants. However, because of the high reactivity of organic matter, by-products that do not contain nutrients can be made. These by-products can induce ...
