TDS in water

What is TDS?
Where do TDS come from?
Why measure the TDS level?
How to reduce or remove the TDS?

Did you know:
...Different government agencies have different requirements for water quality. For example:
  • The U.S. EPA sets the maximum contaminant level for TDS at 500 ppm.
  • The World Health Organization (WHO) sets the maximum contaminant level for TDS at 1000 ppm.
