What does TDS measure in water quality analysis?

Total Dissolved Solids (TDS) measures the combined content of all organic and inorganic substances present in a liquid, specifically water. This encompasses a wide range of dissolved substances including minerals, salts, and organic compounds that are not suspended solids. TDS is crucial in assessing water quality because it can influence the water's physical, chemical, and biological characteristics. High levels of TDS can affect water taste, hardness, and its suitability for various uses, such as drinking or agricultural applications. Understanding TDS is essential for determining the overall health of water sources and ensuring the safety and quality of drinking water.
