How Pure is Your Water?

Water is an excellent solvent and easily picks up impurities. Chemists define Dissolved Solids as "any minerals, metals, salts, cations or anions dissolved in water".

Total Dissolved Solids consist of inorganic salts (mainly calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates) and
some small amounts of organic matter which are dissolved in water.
