What does TDS stand for in water quality testing?

TDS stands for Total Dissolved Solids, which refers to the sum of all inorganic and organic substances present in a liquid that are small enough to pass through a 2-micron filter. This measure is crucial in water quality testing as it provides insights into the concentration of dissolved materials that can affect water's physical and chemical properties. Elevated levels of TDS can indicate potential problems for drinking water quality, as it may suggest the presence of harmful contaminants, including salts, minerals, and metals. Monitoring TDS helps water treatment facilities assess and manage water quality, ensuring safety and palatability for consumption.
