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.
TSS are particles that are larger than 2 microns found in the water column. Anything smaller than this is called a dissolved solid.
