How to read the labels on spring water bottles?
On a spring water label, check the water type (spring, mineral, purified, artesian, sparkling), the named source, and any statements such as low mineral content or from a community water system. In the US, these terms have legal definitions. Spring water must come from an underground formation that flows naturally to the surface and the spring location must be identified.

What do the terms on a bottle mean?
In the US, the FDA defines bottled water types (21 CFR 165.110). If a label uses one of these words, the water must meet the definition.
| Label term | Meaning |
|---|---|
| Spring water | From an underground formation that flows naturally to the surface. Collected at the spring or through a borehole into the same formation, and the spring’s location must be identified. |
| Mineral water | At least 250 ppm total dissolved solids, from a protected underground source, with consistent mineral levels and no added minerals. |
| Artesian water | From a well tapping a confined aquifer where the water level rises above the top of the aquifer. |
| Purified, distilled or demineralized | Treated by distillation, deionization, reverse osmosis or similar processes. |
| Sparkling | Carbon dioxide after treatment equals the level at the source. |
What statements should you look for?
- Source: a named spring or location is a good sign.
- Low mineral content or high mineral content: required on mineral water below 500 ppm or above 1,500 ppm total dissolved solids.
- From a community water system or from a municipal source: required if the water comes from a public supply. It means the water comes from a public supply.
- Not sterile: if the label suggests use for infants and the water is not commercially sterile, it must say so.
- Ingredients: look for added minerals, flavors or sweeteners.
How to compare brands
- Find the type and source.
- Look at the nutrition or mineral panel for sodium and total dissolved solids.
- Check whether the bottler publishes a water quality report on its website.
Is spring water healthier?
The label does not make it so. Regulated tap water and bottled water both must meet safety rules. Pick for taste, price and plastic use.
This is general information for the US. Other countries have different rules.
