Query on dissolved solids

Need help to understand these terms


I have a few questions regarding dissolved solids. Could you share information on the following:

  1. What is the range of dissolved solids in drinking water in the country?
  2. How does the total dissolved solid in water affect our health?
  3. What do these terms actually mean: TDS 10 / TDS 35?
  4. what should be the TDS levels for potable water?
