Water Treatment FAQs

What's the difference between various kinds of bottled waters?

Have you purchased bottled water lately? Did you notice all the different and often confusing varieties that are now available? Water that is classified as "bottled water" or "drinking water" is regulated by the Food and Drug Administration (FDA) to maintain certain standards.

According to the FDA, for a product to be considered “bottled water”, it cannot contain sweeteners or chemical additives (other than flavors, extracts or essences) and must be calorie-free and sugar-free. Flavors, extracts and essences -- derived from spice or fruit -- can be added to bottled water, but these additions must comprise less than one percent by weight of the final product. Beverages containing more than the one percent by weight flavor limit are classified as soft drinks, not bottled water.

The FDA defines the various water types as follows:

  • Artesian Water: Bottled water from a well that taps a confined aquifer (a water-bearing underground layer of rock or sand).
  • Mineral Water: Contains no less than 250 parts per million of total dissolved solids (minerals). No minerals can be added to this product.
  • Purified Water: Water labeled as “purified” can be derived from either distillation, deionization or reverse osmosis.
  • Sparkling Water: Water that after treatment and possible replacement with carbon dioxide contains the same amount of carbon dioxide that it had at emergence from the source. (An important note: soda water, seltzer water and tonic water are not considered bottled waters. They are regulated separately and may contain sugar and calories. These types of waters are considered soft drinks.)
  • Spring Water: Bottled water derived from an underground formation from which water flows naturally to the surface of the earth.
