TDS (Total Dissolved Solids) are measured by the amount of dissolved minerals and ions in water. TDS is an excellent indicator for measuring the quality of a water source and ensuring that it meets the standards needed for safe consumption. As we look toward a more sustainable future, not only will we need to consider our water sources and the means through which they are treated, but we will also have to increase awareness regarding the safety of what we consume every day.
What Are TDS?
Total dissolved solids (TDS) is a measurement of the concentration of dissolved substances in water. TDS water full form is Total dissolved solids (TDS).The TDS percentage is calculated by adding together all forms of dissolved solids and dividing it by the total volume of water. The most common forms of dissolved solids are calcium and magnesium, plus smaller amounts of potassium, sodium and other ions.
Why TDS is important in drinking water?
Total dissolved solids (TDS) is any substance that passes into solution when the water is heated or frozen. TDS can originate from natural sources, sewage, urban run-offs, industrial wastewater, chemicals in the water treatment process, chemical fertilizers used in the garden and plumbing. Water is a universal solvent and easily picks up impurities. Although elevated levels of TDS in drinking water is not a health hazard, it does lend the water a bitter or salty taste. Calcium and magnesium are two minerals commonly found in TDS which also cause scale formation, staining and increased hardness of water.
What are Different TDS levels?
TDS level is a measure of dissolved minerals, salt, and metals in water. TDS can be used to determine whether drinking water is fit for consumption, requires filtration or is highly contaminated. Parts per million (PPM) is the measurement used for measuring TDS level in the water.
Drinking Water TDS Level Chart
| TDS in Water (measured in PPM) | Suitability for Drinking Water |
| Between 50-150 | Excellent for drinking |
| 150-250 | Good |
| 250-300 | Fair |
| 300-500 | Poor, not good for drinking |
| Above 1200 | Unacceptable |
Why You Should Measure TDs Levels?
One important thing to note is that TDS levels over 1000 PPM can alter the flavor of water and cooking food. The taste of both water and food cooked in high TDS level water will change. Meat, eggs, and fish are particularly susceptible to a bad flavor when cooked at high levels.
What are the guidelines for TDS?
TDS refers to Total Dissolved Solids, which is a concentration of dissolved minerals and salts found in water. In Canada, substances that are considered to be dangerous in high amounts are listed as Maximum Acceptable Concentrations (MACs) in the Canadian Guidelines for Drinking Water Quality. However, substances that are not considered dangerous at their MAC, such as TDS, are given an aesthetic objective in the Guidelines.
The Canadian guideline for TDS is less than 500 milligrams per litre (which is the same as 500 parts per million). However, since the Canadian guidelines are not enforceable, each province is free to choose whether or not they will follow the guidelines. Saskatchewan has water that naturally contains high concentrations of TDS, so the province has chosen to not follow the Canadian guideline of 500 parts per million, and to implement its own guideline of 1,500 parts per million.
