Total dissolved solids (TDS) is a measure of the combined inorganic and organic substances dissolved in water. It is directly related to the electrical conductivity of water and as such can be used as an indication of change.
TDS is only relevant in freshwater systems as salinity will dramatically increase the conductivity and therefore apparent TDS.
