The Volcanic Filtration Process
Volcanic water is not collected from a lava flow but rather begins as snowmelt or rain at a volcano's summit. This water then trickles down through thousands of feet of porous, ancient lava rock. This geological journey acts as an exceptional natural filter, removing many impurities and contaminants that might be present in surface water. As the water permeates the layers of volcanic rock, it is naturally infused with a unique blend of minerals and electrolytes. This process gives commercially sourced volcanic water its signature smooth taste and natural mineral content.
The Purification and Enrichment Process
- Natural Filtration: The microscopic pores within the lava rock trap and remove impurities, acting as a natural sieve.
- Mineral Infusion: The long journey through the rock allows the water to dissolve and pick up beneficial minerals like silica, potassium, magnesium, and calcium.
- Alkaline Balancing: The mineral content, particularly magnesium and calcium, can naturally increase the water's pH, making it alkaline without the need for artificial ionization or additives.
Benefits of Commercially Sourced Volcanic Water
Reputable brands responsibly source their volcanic water from deep, protected aquifers, ensuring a safe and consistent product. These commercially available versions offer several potential benefits:
- Rich in Minerals: As water percolates through volcanic rock, it absorbs essential minerals like silica, calcium, and magnesium. Silica is particularly noted for potential health benefits related to skin, hair, and nail health.
- Naturally Alkaline: The presence of alkaline minerals gives the water a higher pH, which proponents claim can help neutralize acidity in the body.
- Pure and Untouched: The extensive filtration process means the water is exceptionally pure, often with a low total dissolved solids (TDS) content, resulting in a clean and crisp taste.
- Electrolyte-Enhanced: The natural minerals also act as electrolytes, aiding in hydration and replenishment, which is why it is often sought by athletes.
The Dangers of Untreated Volcanic Water
It is critically important to distinguish between commercially bottled volcanic water from protected, dormant sources and untreated water near active volcanic sites. Raw water from streams, lakes, or rainwater tanks following a volcanic eruption can pose serious health risks.
- Volcanic Ash Contamination: Ashfall can significantly increase water turbidity, making it cloudy and potentially rendering standard disinfection methods like boiling ineffective. The ash itself is abrasive and corrosive.
- Chemical Leachates: Freshly erupted ash carries a coating of water-soluble substances, or leachates, including acids and salts. These can include hazardous elements like fluorine. While the concentration decreases with distance, water sources close to a volcano can become temporarily toxic. High levels of fluorine have historically led to poisoning in livestock grazing on contaminated land.
- Increased Acidity: In some cases, volcanic gases dissolving in lake water can cause extreme acidity, with pH levels low enough to cause skin burns.
Volcanic Water Sources: A Comparison
| Feature | Commercial Bottled Volcanic Water | Untreated Water Near Active Volcano | Potential Risks |
|---|---|---|---|
| Source | Deep, protected aquifers under dormant volcanoes. | Rivers, lakes, or rainwater collected after an eruption. | Varies by source. |
| Filtration | Natural filtration through thousands of feet of porous lava rock. | Minimal to no filtration from source to collection point. | Contamination of source possible. |
| Mineral Content | Naturally infused with beneficial minerals like silica, calcium, magnesium. | Can be temporarily enriched but often with hazardous leachates. | Chemical toxicity from leachates. |
| Purity | Exceptionally pure due to extensive natural filtration and controlled collection. | High risk of contamination from volcanic ash and debris. | High turbidity, presence of glass shards, corrosive compounds. |
| pH Level | Naturally balanced and alkaline (e.g., 7.6-8.8). | Can become highly acidic, especially in crater lakes or after fresh ashfall. | Extremely low pH causing burns. |
| Safety | Consistently safe, tested, and regulated for drinking. | Unsafe for consumption without rigorous and specific treatment. | High risk of poisoning, waterborne illnesses, and physical harm. |
Evaluating Different Sources
When considering volcanic water, the source is everything. Products from reputable brands like Waiākea or Kelzai leverage ancient, geological processes to produce a consistent and safe bottled product. The long journey through dormant volcanic rock ensures purification and mineral enrichment. This is a very different scenario from consuming water from sources affected by recent volcanic activity, where the risks far outweigh any potential benefits.
Furthermore, not all mineral waters are the same. Volcanic filtration offers a unique mineral profile that differs from other spring waters. For instance, some volcanic waters contain unique trace elements like colloidal gold and silver due to their journey through specific geological formations, offering additional benefits. The 'young' nature of some volcanic waters, due to constant flow through the rock, also reduces the chance of stagnation and contaminant accumulation.
Conclusion
So, is volcanic water good to drink? The answer is a clear yes, but with a critical caveat: it depends entirely on the source. Commercially bottled volcanic water, sourced from deep aquifers protected by ancient lava fields, is a safe, pure, and mineral-rich beverage. Its journey through porous volcanic rock naturally purifies it and infuses it with beneficial minerals like silica, calcium, and magnesium. However, untreated water collected near an active volcano poses significant health hazards due to contamination from ash, toxic chemical leachates, and potential acidity. Therefore, while enjoying bottled volcanic water can be a healthy choice, it is vital to never consume water from an unregulated source near a volcano. For more information on volcanic hazards, consult the official U.S. Geological Survey (USGS) website for up-to-date safety guidelines. Learn more about volcano hazards from the USGS here.
The Future of Volcanic Water
The unique properties of volcanic rock are not just limited to natural drinking water. Researchers are exploring how volcanic rock can be used to improve synthetic flocculants for treating wastewater. This shows the potential of volcanic geology beyond simple hydration, highlighting the valuable mineralogical properties inherent in these formations. The study of volcanic water is a fascinating intersection of geology, chemistry, and health, with both ancient wisdom and modern science confirming its unique attributes.
