What is Aquafina?
Aquafina is a brand of purified bottled water, not spring water. A common misconception stems from marketing and the general perception of bottled water. Aquafina's source is explicitly stated as public water systems on its labels, a practice that began in 2007 following scrutiny from environmental advocates. Owned by PepsiCo, the brand competes with other large-scale producers of purified water, such as Coca-Cola's Dasani.
The Hydro-7™ Purification Process
Aquafina prides itself on its state-of-the-art purification process known as HydRO-7™. This seven-step system is designed to remove nearly all Total Dissolved Solids (TDS), trace compounds, and other substances that can affect water's taste. The process ensures a consistent taste and a very low TDS level, which Aquafina claims to be significantly lower than federal standards.
Here is a breakdown of the key stages involved:
- Pre-filtration: The process begins by removing larger particles from the water.
- Reverse Osmosis (RO): This is a critical step where high pressure is used to force water through semi-permeable membranes. This removes salts, chlorides, and other dissolved solids, significantly reducing the TDS.
- Carbon Filtration: Activated carbon filters are used to isolate and remove elements that affect the taste and odor of the water.
- Ozonation and UV Light: After the primary filtration, the water is disinfected using ultraviolet light and ozonation. This acts as a final safeguard to eliminate any remaining bacteria and viruses, ensuring a high level of purity.
What is Spring Water?
In contrast to Aquafina, spring water is defined by its source. It is derived from an underground formation from which water naturally flows to the Earth's surface. While spring water is also treated for safety to remove bacteria and contaminants, it typically retains many of the naturally occurring minerals and dissolved solids that are absorbed as the water travels through the ground. Brands like Evian, Fiji, and Voss are examples of bottled spring or artesian water. The mineral content in spring water contributes to its unique taste profile, which can vary depending on the geological region it comes from.
Purified Water vs. Spring Water: A Comparison
| Feature | Aquafina (Purified Water) | Spring Water |
|---|---|---|
| Source | Public municipal water systems | Underground formations where water flows naturally to the surface |
| Purification | Rigorous multi-step process (HydRO-7) including reverse osmosis, carbon filtration, and UV treatment | Minimal treatment to remove bacteria and contaminants, preserving natural mineral content |
| Mineral Content | All trace compounds and dissolved solids are removed, resulting in very low TDS | Retains naturally occurring minerals and dissolved solids, contributing to a unique taste |
| Taste | Often described as 'taste-free' or 'clean' due to the removal of minerals | Varies based on the mineral content, can be described as more complex or 'minerally' |
The Taste Debate: Why It Matters to Consumers
For many, the choice between purified and spring water comes down to taste preference. Some consumers prefer the consistent, neutral taste of purified water like Aquafina, free from any mineral aftertastes. Others appreciate the nuanced and mineral-rich flavor profile of spring water. The intense purification of Aquafina removes trace elements like calcium and potassium, which are naturally present in spring water. While these minerals are beneficial, Aquafina's manufacturers argue their levels in most water are too minute to have a significant health impact, and their removal ensures a purer taste. This focus on a 'perfect taste' has been a key marketing point for the brand.
Environmental and Economic Considerations
Both purified and spring bottled waters have environmental impacts related to plastic packaging and transportation. Aquafina, sourced locally from municipal water supplies, may have a smaller carbon footprint from shipping compared to international spring water brands that are transported across vast distances. The bottled water industry has faced criticism for its use of single-use plastic, and Aquafina has addressed this by reducing the weight of its bottles to lessen its environmental impact. However, the debate continues over the environmental cost of extracting and bottling water, regardless of the source. Ultimately, the choice between Aquafina's purified water and natural spring water depends on personal taste preferences, a desire for consistent quality, and an individual's priority concerning mineral content and environmental impact.
Conclusion
In summary, Aquafina is purified bottled water, not spring water. Its journey from a public water source to the bottle involves a multi-stage Hydro-7™ process that meticulously filters out minerals and dissolved solids. This creates a consistently pure and neutral-tasting product that differs significantly from natural spring water, which retains its mineral profile. Knowing this distinction allows consumers to make an informed choice based on their priorities, whether they favor consistent purity or a taste influenced by naturally occurring minerals.
