Study Finds Microplastic Contamination in Most Bottled Water

The plastic water bottles consumed on the go, in aircraft, in hotel rooms, and at fitness centers may have an ingredient the buyer didn’t bargain for, according to a recently released study.

A study conducted by researchers at the State University of New York at Fredonia, in partnership with Orb Media, a non-profit journalism organization, found that almost all bottles tested had microplastic contamination.

The researchers tested 259 water bottles from 11 brands that included Aquafina, Dasani, Evian, Nestlé and San Pellegrino, and found that 93% of those were contaminated. The bottles were purchased in 19 locations in nine countries.

The study found an average of 10.4 microplastic particles about the width of a human hair per liter, twice the amount of contamination found within tap water in a separate, earlier study conducted by Orb Media. They also found significant variation between bottles of the same brand and lot.

Within one brand, Gerolsteiner, where both glass and plastic bottles of water were tested, there was “considerably less” microplastic contamination found in the glass bottles than in the plastic.

Polypropylene, the material used to manufacture bottle caps, was found to be the most common polymeric material, with Nylon in second place.

Researchers concluded that at least part of the contamination arises from the plastic packaging and the bottling process itself.

Meanwhile, the World Health Organization said Wednesday that it plans to launch a review into the potential risks of plastic found in drinking water.
