Microplastics in Fiji water: premium source, same PET bottle.
Fiji water is marketed as artesian water drawn from a single protected aquifer in Viti Levu, Fiji. The source is high quality. But in the 2018 SUNY-Fredonia/Orb Media bottled water study, Fiji samples still came back positive for microplastics. Premium source doesn't fix the PET bottle problem — and the bottle is where most of the plastic comes from.
What the research found
Fiji was one of the 11 brands tested by Dr. Sherri Mason's SUNY-Fredonia team in 2018. Across all 259 bottles tested, 93% had detectable microplastics at an average of 325 particles per liter. Fiji was in the middle of the pack — below the worst offenders, well above zero. None of the premium or “glacier” brands came back clean.
The 2024 Columbia nanoplastics study pushed the numbers higher with more sensitive Raman spectroscopy — ~240,000 particles per liter on average across tested PET bottled water. The takeaway is the same: PET bottles shed, regardless of what the water inside was before bottling.
Why premium source doesn't help
PET (the plastic in most single-use water bottles) sheds microscopic particles as a function of heat, UV exposure, compression, and time. Water that ships from Fiji to your local grocery store spends weeks in shipping containers — many of which get hot — and then sits on shelves. Every hour adds shedding.
The irony of Fiji is the branding. You're paying a premium for untouched source water, then that water sits in a plastic container for months picking up plastic from the container. The source is pristine. The delivery system is not.
Test your own bottle
The Water Test at-home kit lets you run the same measurement on the bottle of Fiji in your fridge. $50 for two tests. Pour 100 mL, stain with Nile Red, filter through PTFE, shine the blue LED. Plastic glows pink. Take a photo.
Real customer result from a bottled water sample.
A useful pair: one test on Fiji, one on your tap water. If your tap has a decent filter, it will often come back cleaner than the Fiji. This is the comparison almost no one runs, and almost everyone is surprised by.
