What Is it?
Aluminium is the most abundant metallic element around. It constitutes about 8 percent of the earth’s crust.
Where does it come from?
Given its abundancy, there will be trace amounts of aluminium in any water source. It is also said that aluminium levels in water sources near newly forested areas can increase due to runoff. Whenever one sees an exceedance of aluminium in their water supply however it is more than likely due to insufficient levels of aluminium coagulant being used in municipal water treatment facilities.
Does it pose a harm to health?
Large aluminium intake is connected with nerve damage. People with poor kidney function are particularly vulnerable to acute aluminium poisoning. There is a weak correlation between aluminium intake and the incidence of Alzheimer’s disease.
How do I know if there’s aluminium in my water?
The best way to find out the aluminium content of your water is to get a test from an accredited laboratory. A full heavy metals test may be purchased here.
What do I do if I find an exceedance of Alluminium?
Municipal water authorities will put a flocculating agent in the water in order to remove excess amounts of aluminium. If you have carried out water test of the water coming into your house and you find an exceedance of aluminium there it is best to invest in a ultra-filtration system or a reverse osmosis system.
