Silver

Source of Silver

Silver (Ag) is a white, precious, metallic chemical element found in natural and finished water supplies. Silver oxide can be used as a disinfectant, but usually is not. Chronic exposure to silver results in a blue-gray color of the skin and organs. This is a permanent aesthetic effect. Silver shows no evidence of carcinogenicity. Silver has a suggested level of 0.1 mg/l under the US EPA Secondary Drinking Water Standards.

Treatment of Silver

Silver can be reduced by 98% with distillation, up to 60% with activated carbon filtration, up to 90% with cation exchange or anion exchange (dependent on the pH), or up to 90% by reverse osmosis.
