TDS, The “Sciency” Definition:
Dissolved Solids are a measurement of compounds like minerals, salts and organic compounds that are dissolved into water through contact with rock and other surfaces. TDS can be made up of several different types of compounds (including but not limited to): calcium, magnesium, iron, sodium chloride and sulfides (which are compounds frequently found in groundwater supplies).
*Increased levels of TDS (total dissolved solids) may affect taste and appearance of your water.
Low TDS vs High TDS
A high TDS level means there is an increased amount of total dissolved solids, which can affect the taste and appearance of water. A low TDS level means there are fewer dissolved solids and your water is made up of mostly pure water molecules, leaving the purest tasting water.
