<P> Total dissolved solids ( TDS ) is a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular , ionized or micro-granular ( colloidal sol ) suspended form . Generally the operational definition is that the solids must be small enough to survive filtration through a filter with two - micrometer ( nominal size , or smaller ) pores . Total dissolved solids are normally discussed only for freshwater systems , as salinity includes some of the ions constituting the definition of TDS . The principal application of TDS is in the study of water quality for streams , rivers and lakes , although TDS is not generally considered a primary pollutant ( e.g. it is not deemed to be associated with health effects ) it is used as an indication of aesthetic characteristics of drinking water and as an aggregate indicator of the presence of a broad array of chemical contaminants . </P>
