I knew a girl in college that would only drink bottled water. She had convinced herself there was a taste difference. She wouldn't even drink tap water filtered from a brita filter
She was right, there is a big difference.

Try Evian versus the waters sold by Coca-Cola (that are tap-water equivalent) and you can really feel it.

I had a roommate like this. So I set up a blind taste test. I set up 10 tests with two glasses each, most of which had one of each type, but I think 3 had either both bottled or both tap. Regardless, it came out int he end, that he couldn't even tell them apart, let alone have a favorite. For some reason, even after the test, he continued to drink bottled water.
The marketing teams behind bottled water successfully brainwashed people. Most people don’t even realize it
Aren't Brita filters gonna have the same problem as the nanoplastics discussed in this article? The article specifically says that the plastic isn't from the bottles themselves.
Ironically a lot of bottled water is just tap. It's one of the biggest scams out there. You're also generally paying 1600x markup.

There's an obvious taste difference between bottled water Vs straight tap water Vs filtered water, ime. That said, you will get used to the different taste after a couple of days and you won't even notice it, so that's not a good reason to buy bottled water.
I find that water flavour has a strong context-sensitive component. For example, I find water tastes really good when I'm really thirsty or after a workout. Any flavour differences between water sources are completely overpowered by this effect for me.
I’ve been in places with bad tasting tap water. Today I live in East Bay, CA and our tap water is amazing.

If I were faced with the sludge coming out of the pipe in some places, I’d stock up on Brita pitchers. Here, I never go out of my way to filter it.

I think there is a taste difference. Did you ask her to try a blind taste test?
There’s a huge difference
All that plastic must have some taste, right?
Difference from what? Even different municipalities have vastly different tastes from each other.

(That said, it's never bothered me to drink tap water wherever I go, and acclimate quickly. I think the bottled water trend is insane.)

There almost certainly is a taste difference. The mineral content is likely different, and the plastic from the bottle can have an influence, too.

I can definitely taste a difference between our (Pur-filtered) tap water and the cheap bottled water we get.

When I was a kid, I wouldn't drink Aquafina (or Dasani) because they tasted plasticky. I attributed it to them using the same plastic for Cola bottles, without the overpowering flavors to mask subtle tastes from the plastic. I'm not as picky now, but my taste buds have gotten less sensitive and it's also possible they fixed the issue.

The blind group think and hand waving around this topic always astounds me.

Plastics used in water bottles are not water soluable.

Is there ANY hard evidence of harm to human health from ingesting minute quantities plastic dust vs any other kinds of dust?

Most plastics are chemically and biologically inert. That is why they don't break down in nature.

Where is the evidence that they react in the body to cause harm?

A water bottle is not your vinyl shower curtain. It is made of PET or maybe PE. Neither are biologically active.

Polyamide ( nylon ) in water filters is non toxic. You could probably eat a teaspoon of fine nylon powder a day suspended in water for years with no health effects because it would just pass through the body without reacting, mainly excreted with feces. Your intestines are not going to absorb insoluble plastics into your blood. The quantities found in water bottles are far, far, less than a teaspoon.

Is there any study that purports to find a significant quantity of polyamide or PET or PE in blood???

It really seems there is a media generated mass hysteria around safe plastics. Not all plastics are the same. Plastics used for food or drink application are typically PROVEN safe from decades of study. What are we all worried about then?

As long as you can't definitively prove it's harmless, I'd rather avoid the stuff if at all possible.

For example there was a time when publicity recommending cigarettes to pregnant women was a thing.

Because of the we did not like the taste of our tab water and we were concerned with plastic in the water when buying bottled water, we bought a reverse osmosis filter for home. We added a mineral filter to the system so we get some minerals as well (only to improve the taste).

I still quite a fan of this even when I drink water from plastic bottles when I am on the road.

Cost wise I found it evens out per bottle when compared to buy cheap bottled water from e.g. Aldi. However, it is not necessary to carry water bottles anymore which already is quite an improvement and well worth the money.

The article has bad news for ya then...

> the most commonly detected plastic was polyamide, a material commonly used in water filtration systems and "the most popular membrane material used in reverse osmosis

Don't Aldi's water bottles have chlorine like city water does?
I’m still trying to figure out why I can’t buy a drip coffee maker that’s not plastic.

Hot water and an acidic beverage running through plastic every morning. Doesn’t seem good.

Look for a Chemex or a V60 (the non plstic one). But it will involve a bit of labor.
why use a drip coffee make when you could be making some good coffee for about the same price using something like Bialetti Moka Express Espresso Maker?
you can. i use a metal funnel and unbleached coffee filters
I assume the same principle of microplastic contamination applies to some degree, not only to bottled water itself, but also to many other food and drink products where a primary ingredient is that kind of commercial plastic-filtered water. For example, most packaged beverages (soft drinks, alcoholic drinks, etc), and certain packaged or jarred food items.
Are there good reasons why Distillation + Re-Added Electrolytes method isn't used more?
I haven’t been able to find a good distiller. Everything on Amazon looks to be rebrands of the same product which I tried.

It seems once the water is boiling inside it’s vigorous enough to kick particles out with the steam. (And it’s hard to refill without occasionally spilling on the cord which ultimately killed mine)

Cost
It amazes me that people drink plastic bottled water.

I ensure my little boy uses only metal water bottles.

"metal" is too unspecific. You usually want stainless steel, preferrably CrNiMo steel (V4A, 1.4401 or similar).

Aluminium bottles are always coated with plastic in the factory, which flakes off and usually isn't really better than plastic-bottle-plastic, sometimes even worse (containing PTFE, BPA, ...). As soon as the coating is gone, aluminium will dissolve in the water, and aluminium salts are known to be "not good", in addition to the influence on taste. Same for copper, in addition to the hassle to keep copper clean. Steel bottles are better because proper kitchen-quality stainless steel (the one with Molybdenum in it, in addition to Chromium and Nickel) doesn't leech out into common drinks (including salty hot broth, which would stain CrNi steel) and doesn't need inner coating.

My little boy drinks bottled water.

First of all, at least where I live, tap water has chlorine. Which seems to carry some risks (see, e.g. https://pubmed.ncbi.nlm.nih.gov/12594192/).

Secondly, my building has copper and PVC pipes, which are also suspected of having some adverse health effects.

Thirdly, where I live, sometimes (about once per month) tap water comes out brown. Authorities typically say that it's fine to drink, and I suppose they analyze it and it conforms to some official standard, but I'm not going to drink or give anyone brown water. And that also makes me think that maybe the days it doesn't look brown to me, it might be also somewhat brown, just maybe not brown enough for me to notice.

Maybe I'm wrong and plastic from bottles is much worse than these things, but I don't think you should be so amazed that people can prefer bottled water. At the end of the day, it's a matter of picking your poison... with incomplete information.

Interested to see if the findings are applicable to bottled juices, bottled sodas, pex piping, etc. Also canned goods (beers, foods) where there's a plastic liner in the can.

If some of the contamination is "pre bottling" then the issue may be way more pervasive than just bottled water.

Are cans or canned food any better? It's all lined with plastic.
having grown up with in-house water filteration for drinking, from simple uv or charcoal filtering to 14+ stage filteration shebang, it is sad to hear that the source of microplastics might be from the RO process.

i wonder if it is more of an issue for large-scale filteration or even for the ones used at homes. anyways, for our generation and the next microplastics are here to stay (just check the search results here https://hn.algolia.com/?q=microplastics)

> "Previous studies found the major chemical composition to be PET, which is expected since the bottle is made of PET," Yan told us. "Therefore, for a long time, we had the impression that the majority of plastic particles inside bottled water would be Polyethylene terephthalate (PET) particles of a few hundred nanometers in size."

> "That was incorrect," Yan said.

Too different from the title. And the other comments seem to have been written without reading the text.

This is unfortunate news given that I have a plastic water filter on my house.
> the most commonly detected plastic was polyamide, a material commonly used in water filtration systems and "the most popular membrane material used in reverse osmosis … a common water purification method shared by all three brands [of water tested]

Is this inevitable with a polyamide membrane RO system or is this wear and tear with insuficient maintenance/ part replacement?

My town banned single-use plastic water bottles. Now stores sell water in cans, does that water also contain plastic particles?

It sounds like it doesn't matter:

"Ironically enough, the most commonly detected plastic was polyamide, a material commonly used in water filtration systems and "the most popular membrane material used in reverse osmosis … a common water purification method shared by all three brands [of water tested]," the team wrote in the paper."

I think cans are coated with a chemical unfortunately

> Virtually all metal cans used for food and beverage products are lined on the inside with a coating that uses BPA as a starting material.

It bothers me that so many people drink bottled water in places where tap water is drinkable. But from time to time I'm reminded that even in those places sometimes bottled water is unavoidable. I have friends in Paris that can't drink tap water after they had led poisoning thanks to very old plumbing.
A lot of places are high levels of Chlorine that also have bad effects, for instance in Spain it's pretty high and linked to lung issues when showering.

Here still lead pipes are being discovered in old building, which has proven to lead to significant issues in Brain development of children.

Also often other residue is found of farming & medicine and other things seeping into the ground water.

So sadly finding clean & good water is not easy, bottled or tap.

This is a sentence you can say in places with nice water, but often the mineralization content is very different, the taste isn't really good, etc.
I read these articles and the comments and wonder how many people who are concerned with these things also drink alcohol or drive dangerously or consume unhealthy food. All of which will affect their lives way worse than particles of plastic.
I go to whole foods and fill up a 5 gallon jug of reverse osmosis water for cheaper than a single 8 oz bottle of water.
I can 100% taste the plastic in any bottled water.
