A tool exists that estimates the total dissolved solids concentration of a water sample based on its electrical conductivity. This estimation relies on an established relationship between the two parameters. For example, a water sample exhibiting a high conductivity value is likely to possess a correspondingly elevated concentration of dissolved minerals, salts, and other solids.
The utility of this estimation method lies in its ability to provide a rapid and cost-effective assessment of water quality. Instead of conducting time-consuming and expensive laboratory analyses to directly measure total dissolved solids, conductivity, which is easily measured with portable meters, can be used to infer the TDS value. This is particularly valuable in environmental monitoring, water treatment plant operations, and aquaculture, where frequent water quality checks are essential.
