Total solids (TS) is the sum of both the total suspended solids (TSS) and total dissolved solids (TDS) in the process of water: TS = TSS + TDS. However, a very low concentration of TDS has been found to give water a flat taste, which is undesirable to many people. Absolutely pure water with virtually no dissolved solids, like deionized water, taste flat, can be acidic, i.e., low pH about 5.5, and the long-term consumption of absolutely pure water may cause acidosis (Source). Pure water -- tasteless, colorless, and odorless -- is often called the universal solvent. It also removes healthy minerals, such as calcium and magnesium, and ideally such water should be filtered through a magnesium and calcium mineral bed to add the minerals to the water. TDS is mainly used in the studies of water quality in the natural bodies of water, including surface and ground sources. The Canadian Guidelines for Drinking Water Quality suggest that the pH of drinking water should be between 7.0 and 10.5. Saskatchewan has water that naturally contains high concentrations of TDS, so the province has chosen to not follow the Canadian guideline of 500 parts per million, and to implement its own guideline of 1,500 parts per million.In the United States, substances that are health-based have Maximum Contaminant Levels (MCLs), and are enforceable by law. The TDS concentration is the sum of all filterable substances in water that can be determined gravimetrically. The measurement of total dissolved solids does not indicate that there is specific health risk or threat, but it can be used to provide insight into the status or the water over time and as a warning sign of a potential problem.
