Water, water everywhere — and not a drop to drink.
A study by Orb Media and State University of New York at Fredonia made headlines this week for reporting that, of 250 water bottles sourced from 11 brands in nine different countries, 93 percent of the samples were contaminated with microplastics.
Testing bottles of Aqua, Aquafina, Bisleri, Dasani, Epura, Evian, Gerolsteiner, Minalba, Nestle Pure Life, San Pellegrino and Wahaha water from India, Indonesia, Kenya, Mexico and the United States, researchers identified 325 particles per liter of water, Fox 28 reported.
However, some bottles tested featured concentrations up to 10,000 plastic pieces per liter.
Nevertheless, Fox 28 pointed out that the joint study has not been subjected to scientific peer review and has not been published in a journal.
Speaking out against the findings, International Bottled Water Association President and CEO Joe Doss said that "non-peer reviewed study" aims to “do nothing more than unnecessarily scare consumers,” USA Today reported.
Meanwhile, the World Health Organization confirmed to BBC that it will be launching a new investigation to review the potential risks of plastic in drinking water.
"It's not about pointing fingers at particular brands; it's really showing that this is everywhere, that plastic has become such a pervasive material in our society, and it’s pervading water - all of these products that we consume at a very basic level,” said Sherri Mason, a professor of chemistry at SUNY Fredonia who contributed to the study, told BBC.
Though there is no evidence to date that ingesting microplastics is harmful to the human body, the researchers believe that the implications need to be better understood.
"It's not catastrophic, the numbers that we're seeing, but it is concerning,” Mason said.
The World Health Organization did not immediately return Fox News’ request for comment.
