Natural mineral water must have a stable, documented mineral composition, while spring water does not require this: it is sufficient that it is clean and meets the requirements for drinking water. Both types of water are extracted from protected underground deposits and bottled without disinfection, but only the mineral water label contains full information about its mineral composition and classification (e.g., "low-mineralized"). In Poland, these regulations are defined by the Regulation of the Minister of Health of March 31, 2011, on natural mineral waters, spring waters, and groundwater.
To sum it up
- Mineral water – its chemical composition must be constant (within the limits of natural fluctuations), and the label must indicate the mineral content and the total degree of mineralization.
- Spring water must meet the microbiological requirements of mineral water and the chemical requirements of water intended for drinking consumption; the composition does not necessarily have to be constant.
- Only mineral waters can have phrases like "low mineral content" or "contains magnesium" on their labels.
- For everyday drinking, making tea or drinks for children, spring water or water with a low mineral content are often chosen.
Mineral and spring water – definitions in accordance with the rules.
Natural mineral water — is groundwater that undergoes assessment and general qualification based on geological, hydrogeological, physicochemical, and microbiological parameters, as well as, if the manufacturer wishes to assign it specific properties, pharmacological and clinical characteristics. The key requirement is that its chemical composition and other properties must remain constant (within natural fluctuations) throughout the entire period of water production from a given well.
Spring water It also comes from a documented underground source and undergoes geological, physicochemical, and microbiological assessment. Both at the source and in the bottle, it must meet the same microbiological requirements as mineral water, and in terms of chemistry and organoleptic properties, the same requirements as water intended for human consumption. However, the regulations do not require permanent changes in its mineral composition.
It is important to distinguish between water from a spring and ordinary water. table water – this is spring or mineral water with the addition of certain mineral salts. Medicinal mineral waters, Those used in spas also constitute a separate category - it is better to consult a doctor before using them for medicinal purposes.
Table: What is the difference between mineral water and spring water?
| Characteristic | Natural mineral water | Spring water |
|---|---|---|
| Source | Documented underground water intake | Documented underground water intake |
| Constant mineral composition | Necessary | Not required |
| Chemical requirements | Restrictions on potentially toxic ingredients established by regulation. | Regarding water intended for drinking consumption |
| Mineralization | From very low to high level - indicated on the label. | Not classified; most common spring waters have low mineralization. |
| Label | The name "natural mineral water", the content of characteristic components and total mineralization, the name of the water source. | Well name and manufacturer's details; regulations do not require indication of mineral content. |
| Claims like "contains magnesium"« | Possible after criteria are met. | Unsuitable |
| Disinfection | Unforeseen circumstances – only those types of treatments specified in the rules are permitted (e.g. iron removal, CO2 content modification). | Like in mineral water |
Mineralization level – how to read the markings?
The label of natural mineral water indicates the total dissolved mineral content in mg/l. In accordance with Appendix 5 of the Regulation and § 6, paragraph 7, water may be labeled as follows:
- Very low mineral content – up to 50 mg/l of mineral salts.
- Low mineral content – up to 500 mg/l.
- Medium mineralized – from 500 to 1500 mg/l.
- High mineralization – more than 1500 mg/l.
Manufacturers may also use ingredient claims if the water meets certain criteria: for example, "contains calcium" (more than 150 mg/L calcium), "contains magnesium" (more than 50 mg/L magnesium), "contains bicarbonates" (more than 600 mg/L), or "suitable for a low-salt diet" (less than 20 mg/L sodium). Water containing more than 1.5 mg/L fluoride must carry a warning that it should not be regularly consumed by infants and children under 7 years of age.
Which water is healthier – mineral or spring water?
Neither option is inherently "healthier"—it all depends on your needs. Mineral water , Water, especially water with medium and high mineralization, can supplement your diet with calcium, magnesium, and bicarbonates. It can be beneficial during intense physical activity and sweating. On the other hand, water with high mineralization can be high in sodium, which is important for people with hypertension and other medical conditions. These individuals should check the sodium content on the label and discuss their choice with their doctor.
Spring water Water typically has a mild flavor and low mineral content (check with the manufacturer), making it suitable for daily consumption in large quantities, as well as for cooking and brewing coffee or tea (it reduces limescale buildup). When preparing baby food, choose water labeled "suitable for baby food" and follow your pediatrician's recommendations.
How to choose water in the store?
- Check the common name – it must be indicated on the label: "natural mineral water," "spring water," or "water from an irrigation source." The brand name and images do not indicate the type of water.
- Pay attention to the overall mineralization level – Most people choose water with low or medium mineral content on a daily basis.
- Pay attention to specific ingredients – If you are interested in the content of magnesium or calcium, compare their concentration in mg/l.
- Check sodium and fluoride content , especially in low-sodium diets and in young children.
- Store water Store in a cool, shaded place and drink within a short time of opening.
Frequently Asked Questions (FAQ)
Is spring water mineral water?
No. Both mineral and spring water come from underground wells, but they are two different legal categories. Mineral water must have a consistent mineral composition and be labeled accordingly, while spring water must meet drinking water standards.
What kind of water is best to drink every day?
Spring water or mineral water with low to moderate mineral content are good choices for daily consumption. Water with high mineral content should be consumed in moderation, and sodium intake should be monitored. If you have a chronic medical condition, it's best to discuss your choice with a doctor or nutritionist.
What kind of water should a baby drink – mineral or spring water?
Choose water labeled "suitable for preparing infant formula." This label may indicate that the water meets acceptable levels of sodium, fluoride, nitrites, and nitrates, among other things. Consult your pediatrician about formula preparation methods and the need to boil the water.
What is groundwater?
This is spring water or natural mineral water to which certain mineral salts have been added. It must be labeled as "table water," and this designation cannot be replaced by a trademark alone.
What does "low mineral water" mean?
This is natural mineral water with a total mineral content of no more than 500 mg/l. Water with a very low mineral content contains no more than 50 mg/l.
