To purify water: (including spigot water) one drop of MMS in one gallon of water will remove most heavy metals, and pathogens from the water. The water will be odor free and drinkable within three to ten minutes after mixing. One or two drops of lemon juice will speed the purification process. This drinking water has no health benefits except that metals, microbes, and bacteria are removed from the water. The ClO2 ions sacrifice themselves and disappear.
