pH measures how acidic or alkaline water is on a scale of 0 to 14. Below 7 is acidic, 7 is neutral and above 7 is alkaline.
| Category | pH range |
|---|---|
| Strongly acidic | Below 5 |
| Mildly acidic | 5.0 – 6.9 |
| Neutral | 7.0 |
| Slightly alkaline | 7.1 – 8.0 |
| Alkaline | 8.1 – 9.5+ |
Mostly naturally carbonated waters and a few purified brands. Lower pH comes from dissolved CO₂ forming carbonic acid.
The biggest band — most still spring and mineral waters land here. Clean, balanced and the default for daily hydration.
Naturally alkaline glacial or volcanic-aquifer waters, plus ionized alkaline brands like Essentia that reach pH 9.5.

For sparkling waters, pH can differ depending on whether it's measured at the source or "as sold" after carbonation — dissolved CO₂ lowers the tested pH once bottled. This table lists the most commonly cited figure per brand; where sources disagree meaningfully (e.g. San Pellegrino), the brand's dedicated pH page notes both values.
These waters are alkaline because of natural geology — not because of ionization machines or added minerals. Volcanic rock, limestone and deep aquifers raise pH naturally through bicarbonate and mineral content.

pH 7.7 · slightly alkaline
San Pellegrino is a naturally sparkling mineral water from San Pellegrino Terme in Lombardy, Italy. Despite its CO₂ content, its pH sits at 7.7 — distinctly alkaline. The brand's high bicarbonate level (around 219 mg/L) and rich calcium and magnesium profile buffer the acidity that dissolved CO₂ would otherwise produce.
See the full San Pellegrino profile →pH 7.0 · neutral
Poland Spring sits at pH 7.0 — exactly neutral. The brand draws from multiple spring sources across Maine and blends to a consistent low-mineral profile (TDS around 47 mg/L). Combined with its neutral pH, that delivers the soft, easy-drinking character it is known for.
See the full Poland Spring profile →pH 7.8 · mildly alkaline
Highland Spring measures pH 7.8 — mildly alkaline. The water rises from organically certified land in the Ochil Hills of Perthshire, Scotland, and picks up calcium and bicarbonate as it filters through the underlying rock. That bicarbonate is what nudges the final pH above neutral.
See the full Highland Spring profile →pH 7.2 · lightly alkaline
Evian has a pH of 7.2 — just above neutral. The water spends roughly 15 years filtering through glacial sand at the foot of the French Alps before emerging at the Cachat Spring, building a balanced calcium-bicarbonate profile that lands the final pH in the gently alkaline range.

pH measures how acidic or alkaline a liquid is on a scale of 0 to 14, with 7 being neutral. Each whole step represents a tenfold change in concentration of hydrogen ions, so the difference between pH 6 and pH 8 is a hundredfold shift in acidity.
For bottled water, pH reflects two things: the geology the water moves through (limestone and volcanic rock raise pH, granite tends to lower it) and any dissolved CO₂. It also influences taste — slightly alkaline waters feel smoother on the palate, while acidic sparkling waters read as sharper and more refreshing.
Acidic (pH below 7): mostly naturally carbonated waters like Perrier (5.5), Gerolsteiner (5.9), Apollinaris (6.0) and Badoit (6.0), plus a few purified brands. Dasani (5.6) is the lowest-pH still water in this chart.
Neutral (pH 7.0–7.9): the most common band. Poland Spring (7.0), Evian (7.2), Vittel (7.5), San Pellegrino (7.7), Highland Spring (7.8) and Liquid Death (7.9) all sit here.
Alkaline (pH 8.0+): Acqua Panna (8.0), Antipodes (8.0), Flow Water (8.1), Waiakea (8.2), Icelandic Glacial (8.4), Evamor (8.8) and Essentia (9.5).
When CO₂ dissolves in water it forms carbonic acid (H₂CO₃), which dissociates and releases hydrogen ions — lowering pH. That is why nearly every naturally sparkling water lands in the 5.5–6.5 range. The exceptions are waters with exceptionally high natural bicarbonate (San Pellegrino, Vichy Catalan) that buffer the acidity back toward neutral.
EU bottled water labels list pH as part of the typical analysis, usually next to TDS, calcium, magnesium and sodium. US labels are inconsistent — many do not disclose pH at all. Manufacturer websites and water-analysis PDFs are the most reliable source. Values can drift slightly batch to batch and over the shelf life of the bottle.
For the full mineral composition behind each pH value, see the bottled water mineral content chart. To explore low-mineral options, see low mineral water brands.
San Pellegrino has a pH of approximately 7.7 — slightly alkaline despite being a naturally sparkling water. Its high bicarbonate content (around 219 mg/L) buffers the acidity that dissolved CO₂ would otherwise create.
Poland Spring has a pH of around 7.0 — neutral. The Maine spring sources it draws from produce a low-mineral, soft-tasting water that sits squarely on the neutral line.
Highland Spring has a pH of approximately 7.8 — mildly alkaline. The water filters through the Ochil Hills in Perthshire, Scotland, picking up calcium bicarbonate that gives it its smooth, slightly sweet character.
Most bottled waters fall between pH 6.5 and 8.5. There is no legally mandated pH range; values reflect the source geology. Naturally carbonated waters trend acidic (pH 5.5–6.5) and ionized alkaline waters can reach pH 9.5.
Clinical evidence that high-pH water provides health benefits beyond regular hydration is limited. Healthy adults regulate body pH tightly regardless of what they drink. Alkaline water is generally safe but rarely necessary.
Dissolved CO₂ forms carbonic acid in solution, lowering pH. Most sparkling waters sit between pH 5.5 and 6.5. Brands with high natural bicarbonate (San Pellegrino, Vichy Catalan) buffer this and stay closer to neutral.
Alkaline water has a pH above 7 — typically 8.0 to 9.5. Naturally alkaline water picks up bicarbonate and other minerals from rock (e.g., volcanic filtration). Ionized alkaline water is created by electrolysis in a machine. The two are not the same in mineral content or taste.
No. Mineral content (TDS) measures total dissolved solids like calcium and magnesium. pH measures acidity/alkalinity. A water can be high in minerals but neutral or even slightly acidic (e.g., Gerolsteiner at pH ~5.9). Conversely, some low-TDS waters can be alkaline due to bicarbonate buffering.
