What Are Total Dissolved Solids?

If you’re a homeowner or a water enthusiast, you may have come across the term “total dissolved solids” (TDS) when testing your water. But what exactly are TDS? In this article, we’ll break down what TDS is, how it’s measured, and why it’s important to keep an eye on TDS levels in your water.

What Are Total Dissolved Solids?

Total dissolved solids are a measure of all the substances that are dissolved in water. This includes minerals, salts, metals, and other organic compounds. Essentially, TDS is a way of measuring how “concentrated” your water is with various substances.

TDS is usually reported in parts per million (ppm), which means the number of milligrams of dissolved solids per liter of water. The higher the TDS level, the more total dissolved solids there are in the water.

How Are Total Dissolved Solids Measured?

There are a few different ways to measure TDS, but one of the most common methods is to use a TDS meter. A TDS meter measures the electrical conductivity of your water, which is related to the amount of dissolved solids in the water. The more dissolved solids there are, the higher the conductivity will be.

Another method for measuring TDS is through laboratory testing. In a lab, water samples are evaporated and the residue is weighed to determine the TDS level.

Why Are Total Dissolved Solids Important?

Higher TDS levels can affect the taste and quality of your water, and can also indicate potential health risks. For example, if your drinking water has a high TDS level, it could contain elevated levels of certain minerals like lead or copper.

In addition to potential health risks, high TDS levels can also cause problems for your plumbing and appliances. Minerals like calcium and magnesium can build up in pipes and appliances over time, leading to clogs and reduced efficiency.

How Can You Reduce Total Dissolved Solids?

There are a few different methods for reducing TDS levels in your water. One common method is through reverse osmosis, which uses a membrane to remove dissolved solids from the water. Another method is using a distillation system, which boils water and collects the steam to remove impurities.

It’s also important to regularly test your water for TDS levels and address any issues as they arise. This can include installing a water softener or filtration system, or working with a professional plumber to identify and address any plumbing issues that may be contributing to high TDS levels.

The Bottom Line

Total dissolved solids are a measure of all the substances that are dissolved in water, including minerals, salts, metals, and other organic compounds. Higher TDS levels can indicate potential health risks and cause problems for plumbing and appliances. It’s important to regularly test your water for TDS levels and address any issues as they arise to ensure the best possible water quality for your home.
