Is High TDS in Water Harmful?

Water is essential for life, and it’s something that we all take for granted. We turn on the tap, and clean, refreshing water flows out. But what happens when that water isn’t so clean and refreshing anymore? What if it’s filled with dissolved solids, also known as Total Dissolved Solids (TDS)?

TDS is a measure of the amount of inorganic and organic substances present in water. It’s measured in parts per million (ppm) and can come from a variety of sources, such as minerals leaching from rocks, agricultural runoff, and even human sewage. While some TDS is natural and necessary for our bodies, high levels of TDS can be harmful.

The Dangers of High TDS

When TDS levels are too high, the water can become salty, metallic, or even bitter-tasting. It can also lead to the buildup of limescale in pipes and appliances, reducing their efficiency and lifespan. But the dangers of high TDS go beyond just the taste and appearance of the water. High TDS levels have been linked to a variety of health problems, such as:

  • Dehydration
  • Kidney stones
  • High blood pressure
  • Heart disease
  • Diabetes

It’s important to note that these health problems are typically associated with prolonged exposure to high TDS levels. Drinking water with high TDS levels occasionally is not likely to cause any harm.

What Can You Do?

If you’re concerned about the TDS levels in your water, there are steps you can take to reduce them. One option is to install a water filtration system, such as a reverse osmosis system or a water softener. These systems can remove dissolved solids and impurities, leaving you with cleaner and safer water.

Another option is to test your water for TDS levels. Many cities and towns provide this service for free, or you can purchase a TDS meter for your own use. Once you know the TDS levels in your water, you can take steps to reduce them if necessary.


High TDS levels in water can be harmful to your health and the longevity of your appliances. But by being aware of the issue and taking steps to reduce TDS levels, you can ensure that the water you and your family are drinking is safe and healthy. Invest in a water filtration system or test your water regularly to keep an eye on TDS levels. Clean water is a basic human right, protect it with knowledge and action.
