What is Deer Park water?
Deer Park is a 100% natural spring water brand owned by BlueTriton Brands (formerly Nestlé Waters North America). It's sourced from multiple springs across the eastern US and distributed primarily in the Mid-Atlantic and Southeast.
Deer Park water source
Deer Park is bottled from several protected springs, including sites in Pennsylvania, Maryland, Florida, South Carolina and Georgia. The original source is the Deer Park Spring in Deer Park, Maryland, first bottled in 1873. The label always lists the specific spring(s) used for that bottle.
Deer Park pH level
BlueTriton's official 2024 water analysis report lists Deer Park Spring Water's pH range as 4.7–8.3 — this wide range reflects that Deer Park is bottled from more than a dozen distinct spring sources with their own natural chemistry, not one single spring. Any individual bottle could test mildly acidic, neutral, or mildly alkaline depending on which source supplied it.
Is Deer Park alkaline?
It depends on the batch. Deer Park's pH can range from 4.7 (mildly acidic) to 8.3 (mildly alkaline) across its various spring sources, per BlueTriton's official reporting. It is not marketed as an "alkaline water" in the specialty sense; brands like Essentia (pH 9.5) or Icelandic Glacial (pH 8.4) are consistently and meaningfully higher. See our best alkaline water brands guide.
Deer Park mineral content
| Mineral | mg/L (typical) |
|---|---|
| Calcium | Non-detect – 69 |
| Magnesium | 0.17 – 10 |
| Sodium | Non-detect – 11 |
| Alkalinity (as CaCO₃) | Non-detect – 160 |
| Chloride | 1.1 – 17 |
| Sulfate | Non-detect – 30 |
| Fluoride | Non-detect – 0.15 |
| Total TDS | Non-detect – 240 |
Ranges are from BlueTriton's official 2024 water analysis report and reflect the full spread across Deer Park's 15+ spring sources — an individual bottle will fall somewhere within these ranges, not at every value simultaneously.
Deer Park vs Poland Spring
Both are BlueTriton spring water brands with similarly light, low-mineral profiles and pH that varies by source spring rather than sitting at one fixed number. Poland Spring draws primarily from Maine sources, while Deer Park blends 15+ springs across the Mid-Atlantic and Southeast. Taste and mineral differences between the two are minimal.
Deer Park vs Fiji
Fiji is a higher-mineral artesian water: pH ~7.7–7.89, TDS ~220 mg/L, with significant silica (~88 mg/L). Deer Park is a low-mineral spring water (TDS up to 240 mg/L, but often much lower). Fiji has a softer, silkier mouthfeel; Deer Park is lighter and more variable batch-to-batch. Fiji costs meaningfully more per bottle.
