TDS Level in Drinking Water
Total Dissolved Solids in Drinking Water
In terms of Total Dissolved Solids (TDS), in the U.S., the Environmental Protection Agency (EPA) advises against consuming water containing more than 500mg/liter, otherwise known as 500 parts per million (ppm) of TDS, although many health specialists believe that ideal drinking water should be under 50 ppm or lower. The average tap water in America contains approximately 350 ppm of TDS although it is not uncommon for municipal or local water supplies to exceed this. If TDS levels exceed 1000mg/L, however, it is generally considered harmful to human health and should not be consumed.
