Does Evian have microplastics?
Yes. We bought Evian at a grocery store in Los Angeles and it tested positive for particles consistent with microplastics, with a PET fluorescence signature.
So did the other six brands we tested. Not one came back clean. What follows is the reading, how it was produced, and — the part that matters most — what a fluorescent dye can and cannot prove.
Evian tested positive for particles consistent with microplastics, with a PET signature in line with the rest of the plastic-bottle field. Alpine spring provenance did not separate it from the others.
What the reading is — and isn’t
The number above is a fluorescence signal strength, not a particle count. It comes from staining the sample with undiluted Nile Red, pushing it through a PCTE membrane, and measuring how brightly the retained material glows across three wavelengths. A brand with a higher reading produced a stronger signal from material consistent with plastic. Nobody counted 143 of anything.
The scored brands span a narrow range, from Path at 106 to Dasani at 143. Three brands were not assigned a number in this round. We are not going to rank those three against each other to fill out a list, because we do not have the data to do it honestly.
Nile Red binds hydrophobic material. Plastic is hydrophobic — and so are lipids, oils, and some organic debris. That is why every result here is phrased as particles consistent with microplastics rather than as confirmed plastic. Definitive polymer identification requires spectroscopy, not a dye. Our full error budget, including the contamination sources we know about and the ones we suspect, is published at thewatertest.com/limitations. Read it before you treat any number on this page as gospel.
These are results from an ongoing study, not a peer-reviewed paper. Our method is adapted from published work (Meyers et al. 2022; Leonard et al. 2022); those authors have not reviewed or validated it.
The other six brands
Evian was one of seven bought together and run the same way. Reading any single brand in isolation is a mistake — the finding of the study is not that Evian is bad, it is that the container is the common thread and every brand tested positive.

People also ask
+Does Evian have microplastics?
Yes. In our screening, Evian tested positive for particles consistent with microplastics under Nile Red staining, with a dominant PET fluorescence signature. Nile Red stains hydrophobic material rather than plastic specifically, so this is a screening result, not chemical confirmation.
+What kind of plastic was found in Evian?
The dominant fluorescence signature was PET — the plastic used in water bottles and can linings. The stain indicates material consistent with PET; definitive polymer identification requires spectroscopy, not a dye.
+Is Evian safe to drink?
No regulator has set a health-based limit for microplastics in drinking water, so a positive screening result is not a safety finding. Evian tested positive for particles consistent with microplastics, in the same range as the other six brands we bought — every one came back positive, whether it was bottled from purified tap, spring, or artesian water.
+Is Evian BPA-free?
Evian is bottled in PET (polyethylene terephthalate, plastic #1) — the plastic our screening detected. BPA is used in polycarbonate (plastic #7) and some epoxy resins, not in PET, so Evian's bottle is not a BPA source. That is a separate question from microplastics: PET bottles don't contain BPA, but Evian still tested positive for particles consistent with microplastic shedding in our screening.
+Where does Evian's water come from?
Marketed as natural mineral water. Bottled in PET. That's the utility's/brand's own sourcing claim, not something we independently verified — our test measured what came out of the bottle, not where the water started.
+Which bottled water had the most microplastics?
By screening signal strength, Dasani read highest at 143 and Path lowest at 106 — a narrow band. Three brands (Fiji, Evian, San Pellegrino) tested positive but were not assigned a number this round, so we do not rank them against the rest. Every brand tested positive.
Test your own bottle
We ran Evian once, from one lot. The only way to know what a bottle in your fridge is shedding is to test it yourself. The same Nile Red screen we used here comes as an at-home kit — stain a 100 mL pour, filter it, and count the particles consistent with microplastics under the scope in about 15 minutes.
