TDS, or Total Dissolved Solids, is a measurement of the amount of "stuff" that has dissolved in your water. This is measured in Milligrams Per Liter, or mg/L. For each Third Wave Water Profile, this number can vary because different profiles have different needs for their quantity of minerals. Each of the below measurements could see variations of +/- 10%.
