The paradox

Mountain Valley has all the credentials of a premium spring water — protected source, zero sodium, glass packaging — yet faces a class-action lawsuit that clouds its purity narrative. For the informed buyer, the question is whether the science outweighs the allegation.

Eight key specs, one pattern: Mountain Valley sits in a category with a rare combination — zero sodium, neutral pH, and a century-old protected source — but it competes in a market where Evian and Fiji have deeper clinical and marketing infrastructure.

Specification Mountain Valley Evian Fiji
Source type Protected spring, Ouachita Mountains, AR Natural spring, French Alps (Evian official U.S. homepage (brand’s site)) Natural artesian aquifer, Fiji (Fiji Water FAQs (brand’s site))
Founded 1871 1826 1996
Packaging Glass & aluminum only Plastic & glass Plastic & glass
Sodium (mg/L) 0 ~6.5 (natural) ~17 (Fine Bottled Water (bottled water database))
Calcium (mg/L) Present (approx. 20) 80 (Evian 1L product page (brand’s site)) 18 (Fine Bottled Water – Fiji Water (bottled water database))
Magnesium (mg/L) Present 26 (Evian 1L product page (brand’s site)) 15 (Fine Bottled Water – Fiji Water (bottled water database))
Potassium (mg/L) Present 1 5 (Fine Bottled Water – Fiji Water (bottled water database))
Silica (mg/L) Not disclosed ~10 93 (Fine Bottled Water – Fiji Water (bottled water database))
pH 7.8 7.2 7.7
Total Dissolved Solids (mg/L) ~150 ~350 ~210
Bottom line: The implication: Mountain Valley’s zero-sodium profile is genuinely rare at this price and source tier. Evian and Fiji offer higher mineral loads — which may appeal to athletes or those seeking electrolyte replacement — but come with higher sodium. For sodium-sensitive consumers, Mountain Valley holds a clear advantage.

Is Mountain Valley Spring Water real spring water?

The short answer is yes — with documentation to back it. Mountain Valley Spring Water meets the FDA definition of spring water: it is collected at the point where water flows naturally to the earth’s surface from a confined aquifer in the Ouachita Mountains, and it has been bottled at that same protected source since 1871 (Mountain Valley 2020 Water Quality Report (brand’s disclosure)).

Which bottled water is 100% spring?

  • The FDA defines spring water as water derived from an underground formation from which water flows naturally to the surface. It must be collected only at the spring or through a borehole tapping the underground formation.
  • Mountain Valley, Evian, and several smaller regional brands meet this standard — but many “spring water” labels on the market do not, because some brands use treated municipal water and label it as “spring” only if it meets minimal federal criteria (Evian Water Attributes (brand’s site)).

What is the source of Mountain Valley Spring Water?

  • The water comes from a protected natural spring in the Ouachita Mountains near Hot Springs, Arkansas. The brand has operated at this same site since 1871 (Mountain Valley 2020 Water Quality Report (brand’s disclosure)).
  • According to the brand’s 2020 quality report, the source is monitored before bottling, and the water meets all FDA bottled-water quality standards.

Has Mountain Valley Spring Water been recalled?

  • As of the latest check, the FDA’s recall database does not list a major recall for Mountain Valley Spring Water. However, a class-action lawsuit filed in 2023 alleges that the brand advertised its water as pure despite claims of contamination with carcinogens (ClassAction.org (legal news site)). This allegation has not been proven in court, and the brand continues to sell its product with FDA compliance claims.
Bottom line: Mountain Valley is real spring water from a documented, protected source. The legal allegation is unresolved, but no FDA recall currently exists. For buyers: check the brand’s latest quality report before letting a lawsuit change your purchasing decision.

What Exactly is Spring Water?

Understanding the regulatory definition helps separate genuine spring water from marketing labels. The FDA has specific criteria that must be met for bottled water to carry the “spring water” label.

How does the FDA define spring water?

  • The FDA defines spring water as water derived from an underground formation from which water flows naturally to the surface of the earth at a specific location. It must be collected only at the spring or through a borehole tapping the underground formation that feeds the spring.
  • Spring water must meet the same purity standards as other bottled water categories and cannot be treated beyond minimal filtration or disinfection. If any treatment alters the mineral content, the label cannot say “spring water.”

What minerals are naturally found in spring water?

  • Natural mineral content varies by geological source. Spring waters typically contain some combination of calcium, magnesium, potassium, silica, and bicarbonates. The specific mineral profile depends on the rock layers through which the water travels (Evian Water Attributes (brand’s site)).
  • Mountain Valley’s profile includes calcium, magnesium, and potassium with zero sodium — a relatively rare combination for a spring water sourced from sedimentary rock.
Why this matters

The FDA definition means that any bottle labeled “spring water” that doesn’t originate from a genuine spring is mislabeled. For Mountain Valley, the 150-year track record at a single protected source gives it credibility that newer or less transparent brands cannot match.

What is the healthiest spring water to buy?

If “healthiest” means lowest sodium plus beneficial minerals at a neutral pH, Mountain Valley scores well. But health outcomes depend heavily on individual hydration needs, activity levels, and existing mineral intake from food.

What are the top 5 healthiest bottled waters?

  • Mountain Valley Spring Water — Zero sodium, pH 7.8, calcium, magnesium, potassium. Glass packaging only.
  • Evian — Higher calcium (80 mg/L) and magnesium (26 mg/L), good for electrolyte replenishment. Available in plastic, which raises microplastic concerns.
  • Fiji Water — High silica (93 mg/L) and natural alkalinity (pH 7.7), but contains 17 mg/L sodium (Fine Bottled Water – Fiji Water (bottled water database)).
  • Waiakea — Hawaiian volcanic water with electrolytes and alkaline pH, sold in RPET bottles.
  • Voss — Norwegian artesian water, very low TDS (20 mg/L), neutral pH, in glass or plastic.

What happens to your body when you start drinking spring water?

  • Switching from tap or purified water to natural spring water can increase your intake of calcium, magnesium, and potassium — minerals most adults underconsume. Magnesium alone supports muscle function, nerve health, and sleep quality (Beverage Universe (general wellness blog)).
  • For sodium-sensitive individuals, a zero-sodium spring water like Mountain Valley can help manage blood pressure compared to waters with 10-20 mg/L sodium.
  • The hydration effect is similar across all clean water options — the health difference lies in mineral contribution, not hydration superiority.
The catch

No single water is “healthiest” for everyone. An athlete losing electrolytes needs the calcium and magnesium in Evian or Fiji. A person with hypertension benefits from Mountain Valley’s zero sodium. The healthiest choice is the one aligned with your body’s specific needs and risks.

Where does Mountain Valley Spring Water rank?

Mountain Valley consistently appears in top-ten lists for premium bottled water, but ranking methodology varies. Some judges prioritize taste, others mineral profile or source purity.

Why is Mountain Valley considered the best bottled water by some experts?

  • It has won multiple “Best Tasting Water” awards and is frequently recommended by water sommeliers.
  • The zero-sodium profile and neutral pH (7.8) make it appealing to purists who want nothing added — and nothing removed — from the natural spring.
  • The glass packaging eliminates plastic leaching concerns, a growing factor in premium water rankings.

How does it compare to Evian, Fiji, and other premium brands?

  • vs Evian: Evian has higher mineral content (80 mg/L calcium vs ~20 in Mountain Valley) but contains 6.5 mg/L sodium. Evian is widely available in plastic; Mountain Valley is glass only.
  • vs Fiji: Fiji has 93 mg/L silica, which supports nail and hair health, but also 17 mg/L sodium. Mountain Valley wins for sodium-sensitive consumers.
  • vs European mineral waters: Many European brands (San Pellegrino, Perrier) are carbonated. Mountain Valley is still, which appeals to a different buyer.
The trade-off

Mountain Valley ranks high on taste and purity — but its limited distribution and higher price (often $2-4 per 750ml bottle) mean it competes on exclusivity, not everyday affordability. For the buyer who values zero sodium and glass packaging over mineral variety, it wins. For those prioritizing mineral density or convenience, Evian or Fiji may serve better.

Can you buy Mountain Valley Spring Water in the UK?

Yes, but through limited channels. Mountain Valley Spring Water is available via online importers and some specialty retailers, but it is not widely stocked in mainstream UK supermarkets.
