What's the Cleanest Bottled Water?

The Short Answer

The bottled water landscape has shifted dramatically in the last year. Icelandic Glacial and Saratoga Spring Water (in glass) are currently the safest, cleanest options on the market. Both consistently test with non-detectable levels of PFAS ("forever chemicals") and come in glass packaging that prevents microplastic leaching.

Mountain Valley Spring Water, previously our top pick, is now a Caution due to a major class-action lawsuit filed in late 2025 alleging the presence of arsenic, uranium, and bromoform. Until independent testing clears them, we cannot recommend it as the "cleanest" option.

For sparkling water, San Pellegrino (in glass) remains a safer choice than Topo Chico, which has a history of testing high for PFAS.

Why This Matters

You are paying 2,000x more for bottled water than tap water. You should be getting purity, not plastic soup.

Microplastics are everywhere.

A 2024 study found that the average liter of bottled water contains 240,000 tiny plastic fragments. These enter your bloodstream and can disrupt hormones. The only way to avoid this is to drink from glass or aluminum.

PFAS levels are unregulated.

The EPA limits PFAS in tap water, but bottled water regulation is spotty. Brands like Deer Park and Poland Spring have historically tested positive for these "forever chemicals," which are linked to cancer and liver damage.

What to Look For

Green Flags:

• Glass Bottles: The only material that is truly inert. It won't leach flavor or chemicals.
• "Artesian" or "Spring" Source: Indicates the water comes from a protected underground aquifer, not a municipal tap.
• Recent Lab Reports: Transparency is key. Brands should publish 2025/2026 water quality reports (like Mountain Valley Water Report).

Red Flags:

• "Purified Water" in Plastic: This is usually just filtered tap water (like Aquafina or Dasani) sitting in degrading plastic.
• Sparkling Water in Cans: The liners of aluminum cans often contain BPA or varying types of epoxy resins.
• High TDS with No Report: High Total Dissolved Solids can mean good minerals, or it can mean contamination. Always check the report.

The Best Options

Here is how the top brands rank based on the latest available data and legal filings.

Detailed Breakdown

1. Icelandic Glacial (Best Overall)

Sourced from the Ölfus Spring in Iceland, this water is filtered through volcanic rock. It has a naturally high pH of 8.4, making it alkaline without artificial additives.

• PFAS: Non-detectable.
• Packaging: Available in glass (recommended) and BPA-free plastic.
• Taste: Crisp, clean, unmatched purity.

2. Saratoga Spring Water (Best Domestic)

The iconic blue bottle isn't just for looks—it protects the water from light degradation. Sourced from Saratoga Springs, NY, it is a premium domestic option that avoids the carbon footprint of shipping water from Europe.

• PFAS: Non-detectable.
• Packaging: Cobalt blue glass.
• Note: Ensure you are buying the spring water, not the sparkling, if you want zero carbonation.

3. Mountain Valley Spring Water (The Controversy)

For years, this was the "clean water" gold standard. However, a lawsuit filed in 2025 (Nadel v. Primo Water Corp) alleges that independent testing found arsenic, uranium, and bromoform in the water.

• The Verdict: Proceed with caution. While these are allegations, the specific mention of bromoform (a disinfection byproduct) suggests the water may be treated more heavily than advertised. We are pausing our endorsement until new independent labs are released.

4. Reverse Osmosis Brands (Essentia, Smartwater)

If you can't find glass-bottled spring water, "Purified" water is your next safest bet against biological contaminants.

• Pros: The Reverse Osmosis (RO) process removes almost everything—bacteria, viruses, and PFAS.
• Cons: It also removes beneficial minerals (magnesium, calcium). Plus, they are almost exclusively sold in soft plastic bottles, which means you are likely drinking microplastics.

The Bottom Line

1. Buy Glass. It is the single biggest upgrade you can make. Icelandic Glacial or Saratoga in glass are your safest bets.

2. Filter at Home. The most cost-effective "clean" water is a high-quality home Reverse Osmosis system with a remineralizer. You control the filter changes. Best Water Filter

3. Skip the Sparkling. Carbonated waters (like Topo Chico and LaCroix) consistently test higher for PFAS and can erode tooth enamel due to acidity. Is Sparkling Water Bad For Teeth

FAQ

What is the healthiest water to drink?

The healthiest water is free of contaminants (PFAS, lead, bacteria) but rich in natural minerals (magnesium, potassium). Spring water bottled in glass generally fits this description best.

Does Fiji Water have PFAS?

Fiji Water generally tests well with no detectable PFAS. However, it is sold in plastic bottles, which introduces the risk of microplastic and nanoplastic contamination, especially if the bottle gets warm during transport. Is Fiji Water Clean

Is Smartwater safe?

Smartwater is vapor-distilled, meaning it is very pure and free of PFAS. However, it is re-mineralized with electrolytes and sold in plastic. It is "safe" from a chemical standpoint but "poor" from a microplastic standpoint.

Why is Topo Chico bad?

In a 2020 study by Consumer Reports, Topo Chico had the highest levels of PFAS (9.76 ppt) of any brand tested. While they claim to have reduced this, the brand has lost trust in the wellness community. Is Topo Chico Clean
