Here's what to look for if you want old-fashioned bottled water, according to the FDA:
 
ARTESIAN WATER

Comes from a well that taps a “confined aquifer,” or groundwater below a layer of solid rock or clay. The water level stands at some height above the top of the aquifer. Examples: Evamore, Fiji.

MINERAL WATER
 
Contains dissolved minerals or gases and must have at least “250 parts per million total dissolved solids,” according to the FDA. It has to originate from a geologically and physically protected underground water source. Ironically, the FDA stipulates that no minerals may be added to mineral water. Example: Evian.

PURIFIED WATER
 
Produced by distillation, deionization, reverse osmosis or other suitable purification processes. Also look for “demineralized water,” “deionized water,” “distilled water” and “reverse osmosis water.” Example: Perfect.

SPARKLING BOTTLED WATER
 
After treatment and possible replacement of carbon dioxide, contains the same amount of carbon dioxide that it had at emergence from the source. Examples: Perrier, San Pellegrino.

SPRING WATER
 
roundwater that may rise to the surface through a natural opening in the earth or rock. Note: The water is not necessarily collected in a bucolic setting. Example: Ice Mountain, Poland Spring.
