Colloidal Silver as a water disinfecting agent for swimming pools? Colloidal Silver as an alternative to Chlorine?
Egyptians prevented infection after skull surgery by inserting silver plates. Romans reported the use of silver compounds for medical treatment. Silver dollars were used to purify drinking water by early pioneers. Silver has been used to fill cavities and silver nitrate drops were regularly put into newborn’s to prevent blindness due to possible infection during labor. During World War I, soldiers used silver leaf to treat infected wounds. Colloidal silver was used to treat infection and purify water for centuries. In 1973, it was used in an experiment to treat swimming pools.
In the early 1970’s, the Allegheny County Health Department in Pennsylvania conducted tests in a 152,000 gallon pool which previously had been disinfected by a 50 pounds per day chlorinator. The system was replaced by a silver system for the swimming season. The Health Department took up to 50 daily samples during the experiment. The Health Department concluded that colloid silver “is equal to chlorine in maintaining essentially coliform-free pool water, and is somewhat better than chlorine in destroying pseudomonas and staph aureus organism.”
Colloidal silver is used to disinfect water used by the International Space Station, Russia’s Mir Orbital station and NASA. Numerous airlines use colloidal silver to purify drinking water. The Australian and Swiss government have approved colloidal silver purification for the water in homes, offices and towns. The World Health Organization has approved two forms of colloidal silver to disinfect drinking water in developing countries.
It is legal to use colloidal silver in swimming pools, but state and local laws requiring the use of chlorine still apply. This effectively means that if you wish to use colloidal silver legally in your pool, you most likely have to use it to supplement chlorine.
While it has been demonstrated that colloidal silver is effective in treating swimming pool water, there are no established or detailed regimens for adding colloidal silver to swimming pools as there are with chlorine.
When people are considering using silver for their pools, they should take note that overuse of colloidal silver can result in a condition called argyria. Argyria leads to blue or gray discoloration of the skin and there is currently no treatment for it.
