New study finds that almost all of our bottled water is contaminated

Let's be honest: it doesn't matter if you watch your portions, count your carbs and otherwise do what you can to ensure you're eating healthily, but without the right amount of water per day, all that effort counts for precisely nothing. We've talked before about how dehydration can mess with your body, so I'm sure I don't need to tell you to drink water.

But for those of us thirst-quenchers, there's always the question of how we get our hydration fix. While I like to have a nice cup of tea periodically throughout the day, there are some people who'll fork out the cash for a bottle of Evian, and stay hydrated that way. But a new study says that this might not be such a good idea.

As you have probably figured out by now, most of the bottled water you get comes in plastic. It's lightweight, it won't shatter like glass, and most importantly, it's cheap for food companies to produce, and as a result, cheaper for you to buy. But if I were you, I'd probably steer clear of that bottled water for a while.

That's down to a study, produced by journalism organization Orb Media and researchers at the State University of New York at Fredonia. They carried out research on 259 bottles from 11 different water brands in nine different countries, and the resulting data made for some pretty interesting reading.

On average, the researchers found as much as 10.4 microplastic particles per liter of water, each of which about the width of a human hair. Ew. Even more worryingly, the study revealed that these particles were found in a staggering 93 percent of the bottles sampled.

"Of the 259 total bottles analyzed, 93% showed signs of microplastics. There was significant variation even among bottles of the same brand and lot, which is consistent with environmental sampling and likely resulting from the complexities of microplastic sources, the manufacturing process and particle-fluid dynamics, among others."

Following on from a previous study, Orb found that there was twice as much plastic in bottled water than there was in tap water, and concluded that it could be the result of plastic packaging more than anything. Flagship water brands like Aquafina, Dasani, Evian, Nestlé and San Pellegrino were all sampled in the study.

At this moment in time, it's not clear what effect these plastic particles could have on human health. As much as 90 percent of plastic passes right through the digestive system, but there's always the chance it could get lodged somewhere, and at that point it's not clear what kind of damage this could do.

“We don’t know all the chemicals in plastics, even… There’s so many unknowns here,” added Jane Muncke, chief scientist at the Zurich-based Food Packaging Forum, speaking to Orb. As we all know, staying hydrated is super important, and although the results of this study may be quite worrying, that doesn't mean you should stop drinking. If possible, try to drink tap water instead of bottled, but ensure that you're safe at all times.
