Can the brine in a softener become contaminated?

There has never been a recorded problem involving the contamination of brine in water softeners.

The reason is that:

  • brine kills germs and viruses
  • the water softener is rinsed thoroughly
  • any bacteria left would be of the low HPC variety, which are harmless

Should a major contamination occur in a stagnant water softener it would create a strong smell that would be extremely difficult to drink. If consumed in large quantities, it may cause gastroenteritis.
