Poland Spring PFAS Testing (2026): 1.66 ppt — And a Bigger Problem

Poland Spring is the best-selling bottled water in the Northeast, and it has spent the last several years defending itself on two fronts at once.

The first is PFAS: Consumer Reports’ 2020 lab analysis measured 1.66 parts per trillion of total PFAS in Poland Spring Zesty Lime Sparkling Water — while Nestlé, then the brand’s owner, told CR that its own testing had detected none.

The second is more fundamental. A federal class action has spent years arguing that Poland Spring isn’t spring water at all. In December 2024, a judge refused to throw that case out.

These are separate issues, and they need to be kept separate — but together they explain why a brand with a relatively unremarkable PFAS number carries an outsized trust problem. This guide covers both, honestly.

The Three Numbers That Matter

Poland Spring’s measured level sits at roughly 42% of the EPA’s binding limit and one-third of the industry standard. It exceeds only the EWG’s 1 ppt advocacy guideline — which no regulator enforces and which nearly every carbonated water on the market also exceeds.

What Consumer Reports Actually Found

In September 2020, Consumer Reports commissioned independent lab testing of 47 bottled water products — 35 still and 12 carbonated — screening for 30 PFAS compounds and four heavy metals.

Seven of the 12 carbonated waters came in above the 1 ppt total-PFAS threshold. Here is the full sparkling field, highest to lowest:

Poland Spring landed fourth-highest — middling, not alarming. It tested at roughly one-sixth of Topo Chico’s level.

One related finding worth noting: CR also tested Deer Park, another Nestlé still-water brand, and measured 1.21 ppt — one of only two non-carbonated waters in the entire study to exceed 1 ppt. Nestlé responded that its most recent testing of Deer Park indicated undetectable PFAS levels. The same pattern of company denial recurs across the Nestlé portfolio.

CR’s broader observation was that carbonated waters tested positive for PFAS far more often than still waters — possibly because of the carbonation process, PFAS in the source water, or treatment that doesn’t reduce PFAS below 1 ppt.

The Nestlé Contradiction

Consumer Reports contacted every manufacturer. Nestlé — then the owner of both Poland Spring and Perrier — replied that its own recent testing had not detected PFAS, and that it supported federal efforts to establish PFAS limits.

CR’s lab found 1.66 ppt in Poland Spring and 1.10 ppt in Perrier.

This looks like a flat contradiction. In practice, it usually isn’t — and understanding why matters more than scoring a point:

Detection limits are not zero

“Non-detect” means “below the threshold this lab can reliably measure,” not “absent.” If Nestlé’s laboratory has a reporting limit of 2 ppt for a given compound, a real 1.66 ppt result gets reported, accurately, as non-detect. CR’s lab, using more sensitive methodology, resolves it. Both companies can be telling the truth about their own tests.

“Total PFAS” is a contested calculation

Total PFAS is a sum across dozens of individual compounds, and there is genuine scientific disagreement about how to compute it — particularly whether to include compounds sitting just above the detection floor. Different defensible choices produce different totals from identical raw data. La Croix’s parent company raised precisely this objection to CR’s methodology, and it is a legitimate technical point, even though it doesn’t erase the measurements.

Batch and source variance is real

Poland Spring draws from multiple sources across western Maine. Source water composition varies by site, by season, and by production run. A sample from one bottling line in March is not the same water as a sample from another line in September.

Different samples, different dates

Nestlé’s “recent testing” was not CR’s bottles. Two labs, two sample sets, two timeframes, two methodologies — divergent results follow naturally, without anyone lying.

What settles the question is reproducibility. When independent investigators using different methods converge on similar numbers, the data holds. Mamavation’s subsequent independent testing of the category produced results broadly consistent with Consumer Reports’ 2020 findings — suggesting CR’s original numbers were reproducible.

The Bigger Problem: Is Poland Spring Even Spring Water?

This is a completely separate issue from PFAS, and it needs to be labeled as such — but it is the reason many readers arrive at this page suspicious of the brand, and it deserves an accurate accounting.

In 2017, consumers filed a federal class action alleging that Poland Spring’s “100% Natural Spring Water” labeling was false. The complaint argued that the water is ordinary groundwater drawn from drilled wells and man-made boreholes — not water emerging naturally from a spring, as FDA regulations require for the “spring water” designation.

The original Poland Spring in Poland, Maine — the spring the brand is named after — has been dry for decades. The company acknowledges it no longer uses the original source and points to seven other Maine springs it says it draws from.

Where the case stands

In December 2024, US District Judge Jeffrey Alker Meyer refused to grant summary judgment dismissing the case. He dismissed some claims but ruled that whether Poland Spring qualifies as spring water remains an open factual question under the laws of Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, and Rhode Island.

Meyer noted that the plaintiffs’ geological expert raised genuine factual disputes — including evidence that some of the company’s alleged springs are man-made, and that water extracted from boreholes differs substantially from water emerging naturally at a spring orifice.

The company’s position: geologists and state officials in all eight states have concluded Poland Spring complies with the FDA’s definition of spring water, and each state authorized its sale as such. Nestlé Waters called the lawsuit meritless and has sought dismissal three times.

This is not a health or contamination finding. No one has alleged the water is unsafe. It is a labeling and consumer-deception case about whether the premium “spring water” claim — and the premium price that goes with it — is justified. As of 2026 it remains unresolved.

A separate suit over microplastics and phthalates

A more recent proposed class action alleges that Poland Spring’s plastic bottles introduce phthalates and microplastics, and that this independently undermines the “100% Natural” claim. Central to that filing is Consumer Reports testing that found substantial phthalate content per plastic bottle serving. This too is a labeling and materials issue, distinct from the PFAS measurement.

Who Owns Poland Spring Now?

The brand has changed hands repeatedly, which matters for anyone trying to hold a company accountable:

• 1992–2021 — Nestlé (as Nestlé Waters North America). This is the entity that responded to Consumer Reports in 2020.
• 2021–2024 — Sold to private equity, renamed BlueTriton Brands.
• November 2024–present — BlueTriton merged with Primo Water to form Primo Brands, headquartered in Tampa, Florida.

The 2020 PFAS testing and the 2020 denial both predate the current ownership. Primo Brands inherited both the brand and the litigation.

What 1.66 ppt Actually Means

Four thresholds frame the number:

• 70 ppt — the EPA’s older voluntary advisory for combined PFOA and PFOS. Poland Spring sits at roughly 2.4% of it. This figure is now widely regarded as far too permissive.
• 5 ppt single / 10 ppt combined — the International Bottled Water Association’s member standard. Poland Spring is well under both.
• 4 ppt — the EPA’s April 2024 rule, the first federally enforceable Maximum Contaminant Level for PFOA and PFOS individually in drinking water. Poland Spring’s total falls below this.
• 1 ppt — the Environmental Working Group’s precautionary total-PFAS guideline. Poland Spring exceeds this by 0.66 ppt.

PFAS are called “forever chemicals” because they resist environmental and biological breakdown and accumulate in the body over time. Research associates PFAS exposure with effects on the immune system, cholesterol, thyroid function, and birth weight, and at higher exposures with certain cancers. The risk at low single-digit ppt levels from any one product remains genuinely uncertain — which is exactly why the advisory thresholds diverge by a factor of seventy.

The realistic framing: the question isn’t whether a product contains PFAS — most bottled water and most municipal tap water does — but how much, from how many sources, over how long. At 1.66 ppt, a bottle of Poland Spring Sparkling is a modest contributor. Cumulative daily exposure across all sources is where the actual risk lives.

What’s Changed Since 2020

The EPA’s 2024 rule

In April 2024, the EPA finalized the first legally enforceable national PFAS drinking water standard — 4 ppt Maximum Contaminant Levels for PFOA and PFOS individually, replacing the old 70 ppt voluntary advisory. That is a seventeen-fold tightening, and it reset the entire regulatory frame.

The FDA’s April 2025 bottled water survey

The FDA tested 197 bottled water products for PFAS. Zero samples exceeded EPA limits. This is the most current and comprehensive federal dataset available, and it is substantially more reassuring than the 2020 coverage implied.

Brands have improved

Topo Chico, the worst 2020 performer at 9.76 ppt, dropped to roughly 3.9 ppt after Coca-Cola upgraded filtration — a 60% reduction, now below the EPA’s 4 ppt limit. This demonstrates the levels are addressable when a company chooses to address them.

Poland Spring vs. the Field

A pattern worth noticing: purified and reverse-osmosis waters generally test lower than spring waters. Spring water is bottled close to its natural state, so whatever PFAS is in the aquifer travels into the bottle. RO and purification strip most of it out before bottling. Poland Spring is a spring water — which is precisely why its number is higher than La Croix’s or Dasani’s, both of which start from municipal water and purify it.

That is an uncomfortable irony for the entire premium spring water category: the “more natural” product is, on this specific measure, the less filtered one.

Honest Verdict

On PFAS alone, Poland Spring is fine. At 1.66 ppt it sits below every enforceable regulatory limit, well below the industry standard, and in the middle of the pack. Anyone avoiding it purely on PFAS grounds is applying a standard that would rule out most sparkling water on the market, including brands with better reputations.

The brand’s real problem is trust, not chemistry. An unresolved federal class action over whether its core product claim is even true, a second suit over bottle materials, and a corporate denial that its own independent testing contradicted — that combination is a reasonable basis for skepticism, and it has nothing to do with the 1.66 ppt figure.

Choose Poland Spring if: you want an inexpensive, widely available water and the PFAS number is your only concern. It clears every binding standard.

Look elsewhere if: you’re paying a premium for “natural spring water” and want confidence that the label means what it says — the courts have not settled that question. If PFAS minimization is the priority, Spindrift (0.19 ppt), San Pellegrino (0.31 ppt), and Perrier (1.10 ppt) all tested lower.

The lowest-PFAS option isn’t bottled. A certified NSF/ANSI 58 reverse-osmosis system removes 94–99% of PFAS compounds from tap water, at roughly $0.05 per liter against $1.50–4.00 for bottled — with lower PFAS and more certainty than any bottled brand offers, and no labeling dispute attached.

Frequently Asked Questions

Does Poland Spring have PFAS?

Yes. Consumer Reports’ 2020 independent lab testing detected 1.66 parts per trillion of total PFAS in Poland Spring Zesty Lime Sparkling Water. This is below the EPA’s 2024 enforceable limit of 4 ppt and the bottled water industry’s 5 ppt standard, but above the Environmental Working Group’s precautionary 1 ppt guideline.

Is Poland Spring safe to drink in 2026?

By current regulatory standards, yes. Its tested PFAS level of 1.66 ppt falls below every enforceable US limit, and the FDA’s April 2025 survey of 197 bottled water products found none exceeding EPA limits. The open questions about Poland Spring concern labeling accuracy and bottle materials, not water safety.

Why did Nestlé say Poland Spring has no PFAS?

Nestlé told Consumer Reports its own testing had not detected PFAS. The most likely explanation is a difference in laboratory detection limits — “non-detect” means below a lab’s reporting threshold, not zero. Different methods for aggregating “total PFAS,” different sample batches, and different testing dates can all produce divergent results without dishonesty on either side.

Is Poland Spring actually spring water?

That is currently before a federal court. A class action alleges the water comes from drilled wells and man-made boreholes rather than natural springs. In December 2024, a judge refused to dismiss the case, ruling that whether Poland Spring qualifies as spring water remains an open factual question. The company maintains it complies with the FDA definition and that state regulators in all eight states have authorized its sale as spring water.

Does Poland Spring have more PFAS than La Croix?

Yes. Poland Spring tested at 1.66 ppt and La Croix at 1.16 ppt in the same Consumer Reports study — Poland Spring measured roughly 43% higher. Both are below every enforceable regulatory limit.

Who owns Poland Spring now?

Primo Brands, headquartered in Tampa, Florida. Nestlé owned the brand from 1992 until 2021, when it was sold to private equity and renamed BlueTriton Brands. BlueTriton merged with Primo Water in November 2024 to form Primo Brands. The 2020 PFAS testing and Nestlé’s response both predate the current ownership.

How can I reduce PFAS in my drinking water?

A reverse-osmosis system certified to NSF/ANSI 58 typically reduces PFAS compounds by 94–99%. Activated carbon filters certified to NSF/ANSI 53 for PFOA/PFOS also help, though generally less completely. Boiling does not remove PFAS — it concentrates them.

For practical next steps: check PFAS levels in tap water by state, see how to test your water for PFAS at home, and compare the best under-sink filters for PFAS.
