Sodium in drinking water

The sodium ion is present virtually in all food and drinking-water. Sodium levels in drinking water are typically less than 20 mg/liter but can exceed this levels. Higher levels of sodium may affect the taste of drinking water.

Sodium (salt) cannot be easily removed from drinking water and cannot be removed through boiling or conventional filtration.  

Reverse osmosis, ion exchange or distillation systems can reduce sodium levels.

A small amount of sodium is recommended for drinking water.  While large amounts of sodium can give health problems, sodium is essential for the proper functioning of the body, and drinking reverse osmosis water, or distilled water over long periods of time can be detrimental to your health.
