Mount Franklin Mineral Water is bottled water which has a high level of dissolved minerals (electrolytes), often described as TDS (total dissolved solids). These minerals occur naturally by the route the water takes to reach the aquifer where it is found.
Mineral water is said to be healthier for you than plain filtered or deionized water because it provides the body with various electrolytes and the fluid necessary for proper bodily functions.
"The legal description by the FDA states that the water must come from a protected underground source and must contain at least 250 parts per million in total of dissolved solids, in addition to meeting the bottled water quality standards."

Most mineral waters vary from sweet to bitter or even slightly salty, and may seem to have more body than regular water. The taste of mineral water should have a clean, fresh taste.
