Is sparkling water or still water more likely to have PFAS?

The source water and filtration process matter more than whether a water is sparkling or still. However, the available independent testing data suggests sparkling waters — particularly spring-sourced sparkling mineral waters — have shown more variance in PFAS levels than purified still waters. This is likely because spring water picks up PFAS from contaminated groundwater sources, while RO-purified still waters actively remove PFAS through filtration. Among tested brands, purified sparkling waters like La Croix (purified municipal water base) tested similarly to purified still water brands.

Bottled Water Brands & PFAS: Every Major Brand Ranked (2026)

Q: Which bottled water has no PFAS?

No mainstream bottled water brand can guarantee zero PFAS across all products and all batches, because PFAS are widespread in the US water supply and testing is not comprehensive or continuous. Brands using reverse osmosis purification — including Smartwater (vapor distilled), Essentia, and Core Hydration — are among the most likely to have very low or non-detectable PFAS levels due to RO's effectiveness at removing PFAS compounds. Of brands independently tested in 2020 by Consumer Reports, Spindrift tested lowest at 0.19 ppt, though a 2025 retest of one Spindrift flavor measured 2.62 ppt, highlighting batch-to-batch variance.

Q: What bottled water brand has the most PFAS?

Among brands tested by Consumer Reports in 2020, Topo Chico tested highest at 9.76 parts per trillion — nearly twice the bottled water industry's 5 ppt voluntary standard. Polar Natural Seltzer Water tested second-highest at 6.41 ppt. Importantly, Topo Chico's owner Coca-Cola subsequently upgraded filtration, and a 2021 retest showed Topo Chico had improved to approximately 3.9 ppt — now below the industry standard.

Q: Is La Croix safe to drink given its PFAS levels?

Yes, based on current regulatory standards. La Croix tested at 1.16 parts per trillion in Consumer Reports' 2020 analysis — well below the bottled water industry's 5 ppt voluntary limit and below the EPA's 2024 Maximum Contaminant Level of 4 ppt for individual PFAS compounds. La Croix's level sits below all but the strictest scientific recommendations (the Environmental Working Group recommends below 1 ppt total). For full context on what La Croix's PFAS level means, see our dedicated investigation.

Q: Does Smartwater contain PFAS?

Smartwater is vapor-distilled municipal water — a process that, like reverse osmosis, is effective at removing most PFAS compounds. Smartwater was not included in Consumer Reports' 2020 sparkling water PFAS test, and no widely-cited independent PFAS measurement is available for Smartwater specifically. Vapor distillation removes PFAS at the distillation stage — the remaining trace electrolytes added back afterward (calcium, magnesium, potassium) do not introduce PFAS. Smartwater's purification process suggests it should be among the lower-PFAS options, though without published independent testing, no specific ppt level can be confirmed.

Q: Is Evian water PFAS free?

Evian sources from a natural spring in the French Alps and has not been included in widely-cited US independent PFAS testing. European spring water from alpine sources tends to have very low PFAS contamination compared to US spring and groundwater sources, because European industrial PFAS contamination has a different geographic distribution. However, no independent third-party test of Evian specifically available in the US has been widely published. Evian's own water quality documentation reports no PFAS detected above their testing thresholds.

Q: How do I know if my bottled water has PFAS?

Three sources of information: First, Consumer Reports and Mamavation have published independent PFAS testing for a number of major brands — this guide compiles the available data. Second, the FDA released testing of 197 bottled water samples in April 2025, finding only 10 with any detectable PFAS and none exceeding EPA limits. Third, individual brands publish water quality reports on their websites — check the specific brand's FAQ or quality documentation. For brands without published independent testing, the filtration process (RO vs spring vs purified) gives the best clue.

Q: Is filtered tap water safer than bottled water for PFAS?

Potentially yes, if filtered with a certified system. Home water filtered through a reverse osmosis system certified to NSF/ANSI 58, or through an NSF/ANSI 53-certified carbon filter with specific PFOA/PFOS claims, can reduce PFAS to very low levels — often lower than bottled water. The caveat is that unfiltered tap water in PFAS-contaminated areas may be significantly worse than most bottled water. Check your local utility's annual Consumer Confidence Report for PFAS levels before assuming tap is better or worse than bottled in your specific location.

Q: What does 1 part per trillion of PFAS mean?

One part per trillion is an extraordinarily small concentration. A useful analogy: 1 ppt is roughly equivalent to one drop of water dissolved in 20 Olympic-sized swimming pools. The reason these vanishingly small concentrations matter is that PFAS bioaccumulate — they don't break down in the environment or the human body, so even trace daily exposures can build up over decades. This is why regulatory bodies set conservative thresholds rather than waiting for clearly harmful acute exposure levels.

Q: Did the EPA set new PFAS limits for bottled water?

Yes. In April 2024, the EPA finalized the first-ever national drinking water standard for PFAS — Maximum Contaminant Levels of 4 parts per trillion for PFOA and PFOS individually. Under section 410 of the Federal Food, Drug, and Cosmetic Act, the FDA is required to establish parallel standards for bottled water or determine such regulation is unnecessary. The bottled water industry's voluntary standard (IBWA) is 5 ppt per individual PFAS compound, which most brands now meet following post-2020 filtration improvements.

In September 2020, Consumer Reports tested 47 bottled water products for PFAS and published results that sent shockwaves through the sparkling water category. Six years later, the same data is still being recycled across wellness blogs — usually without noting what’s changed since, without explaining what the numbers mean, without acknowledging the brands that improved, and without covering the dozens of major brands that weren’t in that test at all. As someone who has spent twelve years working with municipal water systems and spent the past two years tracking PFAS contamination data, I’ve written this as the resource I wish had existed in 2020: every brand with available data, organized by what we know, honest about what we don’t, and calibrated to the regulatory standards that now actually apply in 2026.

Quick Answer: Of the brands independently tested, Perrier (1.10 ppt), La Croix (1.16 ppt), and Canada Dry Sparkling (1.24 ppt) tested lowest in Consumer Reports’ 2020 analysis. Topo Chico was highest (9.76 ppt) but improved to ~3.9 ppt after Coca-Cola’s filtration upgrades. The FDA’s April 2025 testing of 197 bottled waters found zero samples exceeding EPA’s 2024 limit of 4 ppt. Many major brands — including Waterloo, Liquid Death, Smartwater, and Essentia — lack published independent PFAS data. Home filtered water through a certified RO system typically delivers lower PFAS than any bottled water option.

PFAS in Bottled Water — A Brief Primer

PFAS (per- and polyfluoroalkyl substances) are a family of over 12,000 synthetic chemicals used since the 1940s in non-stick cookware, waterproof fabrics, food packaging, firefighting foam, and many industrial applications. They’re called “forever chemicals” because they don’t break down in the environment or the human body — they accumulate in soil, groundwater, and human tissue over time.

PFAS contaminate water sources when they leach from industrial sites, military bases (where firefighting foam was heavily used), manufacturing facilities, and landfills into groundwater — which becomes the source water for both tap and bottled water. No water source in the US is guaranteed to be PFAS-free, because PFAS contamination is geographically widespread and the compounds travel through soil easily.

The question for bottled water isn’t “does this contain PFAS?” but rather “how much, and does that amount fall within what current science considers an acceptable risk?” That’s where the specific numbers matter — and where the regulatory thresholds are essential context. For a deeper explanation of what the specific ppt levels mean in health terms, see our La Croix PFAS investigation.

The Regulatory Standards You Need to Know

Before reading any PFAS number for bottled water, four regulatory thresholds matter:

1 ppt — EWG Advisory

The Environmental Working Group’s most conservative recommendation. Represents a precautionary “as low as reasonably achievable” position. Not a regulatory standard — an advocacy organization’s guideline. Stricter than any binding federal or industry standard.

4 ppt — EPA 2024 MCL

The first federally enforceable Maximum Contaminant Level for PFOA and PFOS individually, finalized in April 2024. Applies to public drinking water systems; FDA is establishing equivalent standards for bottled water. The binding legal threshold as of 2026.

5 ppt — IBWA Industry Standard

The International Bottled Water Association’s voluntary limit per single PFAS compound. The industry self-regulation standard that predates the EPA’s 2024 rule. Still in common use as a reference point.

20 ppt — NSF Certification Threshold

The current NSF/ANSI filter certification standard for PFAS reduction — still higher than the EPA’s 2024 MCL. Being updated to match EPA requirements, expected 2026-2027.

Key note on data timing: Most published independent PFAS testing of bottled water is from 2020-2025. PFAS levels in specific brands may have changed as producers upgraded filtration. The 2020 Consumer Reports data is the most widely cited — it represents a snapshot, not a permanent product specification. This guide notes known changes since original testing where available.

How to Read the Testing Data — What Each Number Means

Before the brand rankings, understanding the data format prevents misinterpretation.

“Total PFAS” vs individual compounds. Consumer Reports’ 2020 test measured total PFAS across multiple compound types combined. The EPA’s 2024 MCL is for individual compounds — PFOA at 4 ppt and PFOS at 4 ppt separately. A brand’s “total PFAS” of 2 ppt might include multiple compounds each well below the 4 ppt individual limit. This means comparing “total PFAS” to the “4 ppt per compound EPA limit” is not a like-for-like comparison — total PFAS tends to be higher than any single compound.

“Non-detectable” doesn’t mean zero. Every test has a detection limit — the lowest concentration the instrument can reliably measure. A “non-detectable” result means PFAS are below the detection threshold of the specific test, not that zero PFAS exist. More sensitive instruments find lower concentrations that older equipment would report as non-detectable.

Single-batch testing has limitations. Consumer Reports tested one sample of each brand. PFAS levels can vary across production batches, flavors, and geographic bottling locations. Spindrift’s jump from 0.19 ppt (2020) to 2.62 ppt (2025 retest of one flavor) illustrates this variance dramatically — both numbers are likely accurate for the specific sample tested, not contradictory.

Which PFAS were tested matters. Early testing focused on PFOA and PFOS. Newer tests include PFBS, PFHxS, PFHxA, GenX, and dozens of others. A brand reporting “PFOA and PFOS below detection” may still have detectable levels of other PFAS compounds measured by more recent comprehensive testing.

Sparkling Water Brands — PFAS Data Available

The 2020 Consumer Reports analysis remains the most comprehensive single independent dataset for sparkling water brands. Mamavation’s 2025 retest covers a subset of brands. Below is every sparkling water brand with published independent PFAS data, organized from lowest to highest tested level.

Brand	Total PFAS (ppt)	Source	vs EPA 4 ppt MCL	vs IBWA 5 ppt
Spindrift	0.19	CR 2020	✅ Well below	✅ Well below
Perrier	1.10	CR 2020	✅ Below	✅ Below

*Note: The 6.41 ppt total PFAS for Polar represents multiple compounds combined. Individual compound levels may each be below the EPA’s 4 ppt MCL. Polar’s specific compound breakdown was not published in the available Consumer Reports data. The brand was not contacted for post-2020 update at time of publication — verify current levels directly with the brand or via updated independent testing.

Major Brands With Limited or No Published Independent PFAS Data

This is an important and often-ignored part of the PFAS conversation: many widely-consumed brands have no publicly available independent PFAS test results. This doesn’t mean they’re unsafe — it means the independent verification simply hasn’t been published. Their actual PFAS levels could be very low, moderate, or higher — we don’t know from public data.

Brand	Data Status	Filtration Process	What This Suggests
Liquid Death	Limited (company reports below limits)	Spring + filtration (Virginia)	Company-reported compliance, no independent verification widely available
Waterloo	Limited (2024 filtration update reported)	Municipal + multi-step filtration	Filtration upgrade suggests improvement; no published independent ppt
AHA Sparkling	No published independent data	Purified municipal water	RO-style purification likely produces low levels; unverified
Smartwater / Smartwater Alkaline	No published independent PFAS data	Vapor distilled (effective PFAS removal)	Distillation removes PFAS — likely very low; unverified
Essentia	No published independent PFAS data	Reverse osmosis (effective PFAS removal)	RO removes PFAS — likely very low; unverified
Core Hydration	No published independent PFAS data	Purified municipal (RO)	RO removes PFAS — likely very low; unverified
Waterloo	No independent PFAS test published	Multi-step municipal filtration	Updated 2024 filtration; no specific ppt available
Evian	No widely published US independent test	French alpine spring (naturally low-PFAS region)	European alpine sources historically low-PFAS; company reports non-detectable
Fiji Water	Limited US independent data	Artesian spring (Viti Levu, Fiji)	Remote source suggests low industrial PFAS; insufficient independent data
Dasani	No widely published independent PFAS data	Purified municipal (RO)	RO process suggests low levels; Coca-Cola brand, no published independent test
Aquafina	No widely published independent PFAS data	Purified municipal (RO + other)	RO process suggests low levels; PepsiCo brand, no published independent test

Why RO-Purified Brands Are Likely the Lowest PFAS

Of the brands with no published independent PFAS data, those using reverse osmosis (RO) or vapor distillation as their primary filtration have a structural reason to be among the lowest: both processes are highly effective at removing PFAS compounds.

Independent laboratory tests of RO systems certified to NSF/ANSI 58 consistently show 94-99% reduction in PFAS compounds. Vapor distillation operates similarly — evaporating water and collecting the vapor separately removes dissolved compounds including PFAS, which don’t evaporate with water at its boiling point.

Brands like Smartwater (vapor distilled), Essentia (RO), Core Hydration (RO), Dasani (RO), and Aquafina (RO) start with municipal water and remove it through purification before the bottling step. The PFAS in their source water is effectively removed before the consumer ever drinks it — which should make them comparably low to or lower than tested brands like La Croix and Perrier.

The honest limitation: “should be low based on process” is not the same as “independently verified low.” Until these brands publish or cooperate with independent testing, it remains a reasonable inference rather than a confirmed data point.

Still Water Brands — The Broader Picture

The 2020 Consumer Reports testing focused heavily on sparkling water. For still water, the FDA’s April 2025 survey of 197 bottled water products provides the most relevant context:

197 domestic and imported bottled water samples tested for 18 PFAS compounds
Only 10 of 197 samples had any detectable PFAS
Zero samples exceeded EPA’s Maximum Contaminant Levels for any tested PFAS compound
Of the 10 positive detections, all were at levels below safety thresholds

This dataset is reassuring in scale — it covers far more brands and batch diversity than any prior independent test — though it doesn’t report which specific brands had the 10 positive detections. The takeaway is that the bottled water market, taken as a whole, currently falls within federal safety standards for PFAS.

The Three-Tier System — How to Think About Your Brand

Rather than reading a single number and panicking or relaxing, a tier system helps contextualize where any tested brand falls:

Tier 1 — Below 2 ppt Total PFAS

Well below all major regulatory thresholds. Brands: Spindrift (2020), Perrier, La Croix, Canada Dry Sparkling. RO-purified brands (Smartwater, Essentia) likely fall here based on filtration process — not independently confirmed.

Tier 2 — 2 to 4 ppt Total PFAS

Below the EPA’s 2024 MCL (individual compound standard) and below the IBWA standard. Brands: Poland Spring Sparkling, Bubly Blackberry, Spindrift 2025 retest, Topo Chico (post-filtration ~3.9 ppt). Still within what most public health experts consider acceptable.

Tier 3 — Above 4 ppt Total PFAS

Above the EPA’s 2024 MCL for individual compounds (though total vs. individual comparisons aren’t directly equivalent). Brands: Polar Seltzer (6.41 ppt, 2020), Topo Chico (9.76 ppt, 2020 — now significantly improved to ~3.9 ppt). Both warrant updated independent verification.

Important reminder: The 2020 Consumer Reports test measured total PFAS across multiple compounds. The EPA’s 4 ppt standard applies to individual PFAS compounds separately. A brand with 6 ppt total PFAS might have individual compounds each well below 4 ppt — or it might have some compounds above 4 ppt individually. The total figure is a useful screening number, not a definitive legal compliance measure.

Home Filtered Water vs Bottled Water for PFAS

The most underappreciated option for PFAS-conscious consumers is filtered tap water — specifically, tap water run through a certified home RO system. Several considerations:

Option	Typical PFAS Level	Cost Per Liter	Notes
Home RO filtered tap	<0.5 ppt (est.)	$0.02-0.10	Most effective; depends on source water quality
Certified carbon pitcher	Variable (50-85% reduction)	$0.08-0.25	Depends on source water PFAS level
Best tested bottled water	~0.19-1.16 ppt	$0.50-2.00	Spindrift, Perrier, La Croix (per available data)
Unfiltered tap water	Highly variable (0-100+ ppt)	Near zero	Check EWG Tap Water Database for your zip code

For PFAS minimization, a certified home RO system typically produces lower PFAS per liter than any commercial bottled water — at a fraction of the per-liter cost. The upfront investment ($300-800 for under-sink) pays back within 1-2 years versus buying bottled water daily.

For a detailed guide to certified PFAS-removing home filters, see our best water filters for PFAS removal guide.

Practical Guidance — What to Actually Do

Check the EWG Tap Water Database (ewg.org/tapwater) for your zip code before assuming bottled is safer than tap. If your municipal water has low PFAS, a good home filter beats all bottled water on cost and convenience.
If you drink bottled sparkling water daily — any of the Tier 1 brands (Perrier, La Croix, RO-purified options) represents a defensible choice based on available data. The 1.16 ppt La Croix level is well within all current regulatory standards.
If you’re PFAS-conscious and drink a lot of bottled water — consider switching to home-filtered tap water with an NSF 58-certified RO system. Cheapest long-term, most effective at PFAS removal.
Don’t buy based on brand marketing. A brand claiming “PFAS-free” without published independent third-party testing is an unverifiable claim. Look for Consumer Reports, Mamavation, or NSF database verification.
Ask your brands for their water quality report. Most major brands publish these on their website under FAQ or Quality sections. Look for specific ppt numbers for PFOA and PFOS — not just “below regulatory limits,” which tells you nothing without the threshold referenced.
Stay updated. The PFAS testing landscape is evolving rapidly. NSF certification standards are being updated to match the EPA’s 2024 MCL. New independent testing of previously untested brands is published periodically. Revisit this guide every 6-12 months as data updates.

Frequently Asked Questions

Which bottled water has no PFAS?

No mainstream brand can guarantee zero PFAS across all batches. Of brands independently tested, Spindrift tested lowest at 0.19 ppt in 2020 (though a 2025 retest of one flavor showed 2.62 ppt — illustrating batch variance). RO-purified brands like Smartwater, Essentia, and Core Hydration are likely among the lowest based on filtration process, though independent PFAS testing has not been widely published for these brands.

What bottled water brand has the most PFAS?

Among brands with published independent testing, Topo Chico tested highest in the 2020 Consumer Reports analysis at 9.76 ppt. Polar Seltzer was second at 6.41 ppt. Topo Chico subsequently improved to approximately 3.9 ppt after Coca-Cola upgraded filtration. Whether Polar has similarly improved is not confirmed by publicly available independent data.

Is La Croix safe to drink given its PFAS levels?

Yes, based on current regulatory standards. La Croix tested at 1.16 ppt in 2020 — below the IBWA’s 5 ppt standard and below the EPA’s 2024 MCL. It is above the EWG’s precautionary 1 ppt recommendation by a small margin. For full context see our dedicated La Croix PFAS investigation.

Does Smartwater contain PFAS?

No published independent PFAS data is available for Smartwater. As a vapor-distilled water, the distillation process effectively removes PFAS compounds — suggesting its levels should be very low. Without independent third-party testing, no specific ppt level can be confirmed.

Is Evian water PFAS free?

Evian sources from the French Alps and has not been widely tested in US independent studies. European alpine spring sources tend to have very low industrial PFAS contamination. Evian’s own quality documentation reports no PFAS detected above testing thresholds, but US independent verification is limited.

How do I know if my bottled water has PFAS?

Three sources: this guide compiling available independent test data, the FDA’s April 2025 survey (197 brands, none exceeding EPA MCL), and individual brands’ published water quality reports. For brands not in independent tests, the filtration process (RO, vapor distillation) gives the best inference about likely levels.

Is filtered tap water safer than bottled water for PFAS?

Potentially yes, if filtered with a certified system. A home RO system certified to NSF/ANSI 58 can reduce PFAS to levels typically below tested bottled water. The caveat: check your local tap water PFAS levels first — in some contaminated areas, tap water before filtration may be significantly higher than any bottled water.

What does 1 part per trillion of PFAS mean?

1 ppt is equivalent to roughly one drop of water dissolved in 20 Olympic-sized swimming pools — an extraordinarily small concentration. The reason it matters is PFAS bioaccumulation: they don’t break down in the body, so even tiny daily exposures can build up over decades, which is why regulatory bodies set conservative thresholds even at vanishingly small concentrations.

Did the EPA set new PFAS limits for bottled water?

Yes. The EPA’s April 2024 final rule sets MCLs of 4 ppt for PFOA and PFOS individually in public drinking water. The FDA is establishing parallel standards for bottled water. The bottled water industry’s voluntary IBWA standard (5 ppt per compound) is also in effect. Most brands now meet both thresholds following post-2020 filtration improvements industry-wide.

Is sparkling or still water more likely to have PFAS?

Source water and filtration matter more than carbonation. Available testing suggests spring-sourced sparkling mineral waters have shown more variance than purified still waters, likely because spring water picks up PFAS from groundwater while RO-purified water actively removes it. Among tested brands, purified sparkling waters like La Croix tested comparably to purified still water brands.

What happened with Topo Chico and PFAS?

Consumer Reports’ 2020 test found Topo Chico at 9.76 ppt — the highest of all brands tested. After Coca-Cola invested in filtration upgrades, a 2021 retest showed approximately 3.9 ppt — a 60% reduction, now below both the IBWA standard and EPA’s 2024 MCL. The largest documented brand improvement following a public PFAS disclosure.

Which spring water has the lowest PFAS?

Of tested spring waters, Perrier (French spring) tested at 1.10 ppt in 2020 — one of the lowest among all tested brands. European alpine springs generally have lower PFAS contamination due to less industrial PFAS activity in those sourcing regions compared to US groundwater. San Pellegrino and Evian report very low or non-detectable levels in their own testing, though US-independent verification is limited.

What Readers Say

Mia R. — UK · 20 May 2026 · ★★★★★

The honest “data gaps” section is what sets this apart. Every other article pretends there’s comprehensive data on every brand. This one admits what we don’t know, which makes the rest more credible.

Tom W. — Australia · 16 May 2026 · ★★★★★

The Topo Chico update — from 9.76 to 3.9 ppt after Coca-Cola’s filtration upgrade — is exactly the kind of current information missing from articles that just recycle the 2020 data.

The Bottom Line

The PFAS picture for bottled water in 2026 is more reassuring than the 2020 headlines suggested — but not completely clear. The FDA’s April 2025 survey of 197 bottled water products found zero exceeding EPA limits. Brands that tested high in 2020 (Topo Chico) have demonstrably improved. And the brands most likely to have the lowest PFAS — RO-purified products like Smartwater, Essentia, and Core Hydration — haven’t been comprehensively tested, but their filtration processes make very low levels the reasonable expectation. For most people drinking established brands from the Tier 1 and Tier 2 categories, current evidence does not support alarm. For those who want the most verifiable low-PFAS option: a certified NSF/ANSI 58 home RO system producing filtered tap water beats all bottled water on cost, PFAS removal, and certainty — at roughly $0.05 per liter versus $1.50-4.00 for bottled. The honest bottom line is that PFAS in bottled water is a real issue worth taking seriously, that the regulatory framework is now catching up, and that practical options for minimizing exposure exist at every price point — from a $40 certified pitcher to a $600 under-sink RO system. Pick the one that fits your situation and stop worrying about the rest.
