The term Total Dissolved Solids refers to all minerals, metals, salts, cations and ions dissolved in water. TDS in drinking water can originate from not only natural sources, but sewage, industrial wastewater, urban run-off and chemicals used in water treatment plants.
Run-off and environmental sources include sea water intrusion, carbonate deposits, mineral springs as well as salt used for de-icing roads, anti-skid contamenants, drinking water treatment chemicals and stormwater and agricultural runoff.
The Total dissolved solids test allows for a real measure of the amount of dissolved ions, but does not really tell us the nature of the ions. Therefore the TDS test is used only as a general quality of your drinking water.« Back to Glossary Index
