The level of ions generated has been reported to be usually below EPA Safe Water Drinking Act Lead and Copper Rule AL for copper. [3] The AL for copper in potable water is 1.3 ppm (Cu) and the SCL for silver is 0.1 ppm (Ag) (which is the same as 100 ppb). It is important to collect and handle samples correctly in order to get accurate results.
Smoking has been linked to dementia because it can increase the risk of problems with the heart and blood vessels, the Alzheimer’s Society says. Toxins in cigarettes also cause inflammation ...
Treated water can be allocated as drinking water for households, supply for industrial or agricultural use and the treatment method depends on the purpose of the end-use.

For these water sources to be consumed safely, they must receive adequate water treatment and meet drinking water quality standards. [5]
