Understanding the Differences in Bottled Water
When navigating the bottled water aisle, it’s easy to feel overwhelmed by the sheer number of options and the marketing claims on each bottle. Not all water is created equal, and understanding the differences between terms like "spring water," "purified water," and "mineral water" is key to knowing what you’re actually buying. A product labeled "purified drinking water," for instance, might start as municipal tap water before undergoing a thorough filtering process. In contrast, true natural spring water is collected directly from a naturally flowing underground source, with minimal processing.
What Exactly Is Natural Spring Water?
Natural spring water is groundwater that flows from an underground aquifer to the earth’s surface. It is naturally filtered and absorbs minerals during its journey. FDA regulations require bottled spring water to be collected at the spring's opening or from a borehole tapping the same source. Processing is minimal to preserve its natural state, ensuring safety through methods like filtration or ozone treatment. The label must clearly list the spring source location.
Other Common Types of Bottled Water
- Purified Water: Sourced from various origins, including tap water, this water is heavily treated to remove contaminants and most minerals. Common methods are distillation and reverse osmosis. Brands such as Aquafina and Dasani are examples.
- Mineral Water: Originating from a protected underground source, mineral water is distinguished by a stable, specific quantity of naturally occurring minerals, requiring a minimum of 250 ppm of total dissolved solids. Evian and San Pellegrino are popular choices.
- Artesian Water: This is spring water from a pressurized aquifer, allowing it to rise to the surface naturally. It follows the same minimal processing rules as other spring water. Fiji and Voss are known artesian brands.
- Distilled Water: Produced by boiling and condensing water vapor, this process eliminates all impurities and minerals. It is generally not recommended for regular drinking due to the lack of minerals.
Decoding the Label: How to Verify Natural Spring Water
To identify genuine natural spring water, examine the label for these key details:
- Clear Labeling: The bottle must explicitly say "Spring Water." Other descriptions, like "drinking water" or "purified water," mean it's not natural spring water.
- Source Identification: The label must specify the geographical location of the spring. Look for statements indicating where the water was bottled at the source.
- Indication of Minimal Processing: Many authentic natural spring water brands highlight their minimal processing to show the water's natural purity.
Comparison of Bottled Water Types
| Feature | Natural Spring Water | Purified Water | Mineral Water |
|---|---|---|---|
| Source | Underground aquifer flows to surface | Any source, including tap water | Protected underground source |
| Treatment | Minimal filtration/ozone | Extensive filtration (RO, distillation) | Minimal, to preserve minerals |
| Mineral Content | Naturally occurring, varies by source | Minerals removed; some added back | Stable, specific content (>250 ppm) |
| Taste Profile | Crisp and unique due to minerals | Neutral or flat | Rich, distinctive flavor |
| Cost | Moderate to high | Often more affordable | Tends to be higher-end |
Identifying Brands of Natural Spring Water
Several brands are recognized for providing authentic natural spring water:
- Mountain Valley Spring Water: Sourced from the Ouachita Mountains in Arkansas.
- Evian: From the Cachat Spring in the French Alps.
- Crystal Geyser Alpine Spring Water: Bottled at protected spring sources across the U.S.
- Poland Spring: Sourced from various springs in Maine.
- Icelandic Glacial Water: From the Olfus Spring in Iceland, filtered through lava rock.
Conclusion
Identifying which bottled water is natural spring water requires paying close attention to labels and understanding the different water types. True natural spring water comes from a specific underground source and undergoes minimal processing, as required by FDA regulations. By checking for clear labeling, source location, and indications of minimal treatment, consumers can confidently choose authentic spring water brands like Mountain Valley or Evian. This knowledge empowers better hydration choices based on source, treatment, and desired mineral content.
