back to article Cutting-edge microscopy reveals bottled water has 'up to 100 times' more bits of plastic than previously feared

The average store-bought bottle of water contains somewhere in the neighborhood of 10 to 100 times more minute plastic particles than previously believed, judging from a study published this week. We've long known about the presence of microplastic particles in bottled water and proliferating through nature, while nanoplastics …

      Re: I avoid buying water in plastic bottles

      I also avoid water in plastic bottles, I drink filtered tap water.

      The issue is though, that as per the article, a large part of the microplastics found isn't coming from the bottle itself. Bottled water in a glass container (and tap water too for that matter) is sourced from a spring / underground aquefier and filtered, or derived from reverse osmosis. Either way there are plastics involved in the processing machinery. I wouldn't be surprised if plastics are being picked up from the pipes that deliver tap water.

      However since I don't have a private pristine brook of snow-melt water in an unpolluted corner on the slopes of Mount Inaccessible, I'll just have to make do with avoiding plastic bottles.

        Of course if you do get to Mount "Inaccessible", you'll need a colander to strain out the bear turds, and iodine tablets to kill off the giardia...

        The article does illustrate the perils of analytical technology: the harder you look, the more dirt you find. The relevant question is whether that dirt is a problem. I think there are large areas of the world where people would happily take a bit of microplastic instead of chlamidia, bilharzia, cholera or other nasties in an untreated supply.

          Also, do I prefer my water delivered through plastic pipes (or plastic bottles) containing microplastics, or through lead[0] pipes as in days of yore? (I don't buy bottled water and I don't filter what comes out of the tap. My landlord thinks I'm crazy but last time I checked I wasn't dead yet.)

          [0] Other metals are available, e.g. copper or iron, but I think lead is the least friendly.

            Re: Mount Inaccessible

            What comes out of the tap is supposed to be drinkable anyway.

            But until I was nearly 14 we lived in a house with lead pipes and unfiltered spring water as the source of drinking water. At some point a municipal piped supply was provided but the 3rd tap, the spring water tap was preferred as drinking water. Like you, last time I checked I'm still alive very many decades later.

            According to the directer of the Traad Point water research lab on Lough Neagh lead in potable water only became a problem with central heating and working wives, the combination resulting in water sitting stationary in warmish surroundings for many hours during the day so that the concentration built up. In a multi-generational household with seldom less than two adults in the house and where there would be ice on the inside of the windows on a cold morning that was not a problem.

                  On Victorian houses that still have lead pipes, you don't have a water meter. (Guess how I know that)

                  However, it's still not much more expensive than having a watermeter (and not using any water) because the pipe is so small that it only allows basically one tap to be on at full, and presumably somebody did the math and calculated that it was impossible on a practical level to use enough water to be worth bothering with.

                Now there's a word I haven't seen for a while. In the olden days when chemists used burettes and washbottles and got jobs with the Water Board, they were taught about such things. Apparently soft water, as seen in areas fed from peat covered volcanic geology like western Scotland and north-west England, contains organic acids that do lift a bit of lead off the pipes so flushing is not a bad idea. In hard water areas (on chalky ground) the minerals tend to coat the inners of the pipe so there is less of a danger. In the cities of course, you got plenty of lead from the dust in the car exhausts anyway.

              I've always been told that water straight from a mountain spring - no water upstream - was about the cleanest water you could find. Has minerals, sure, but little to no bacteria/virii and should have no plastics. Drunk fresh, it's also quite cold and, er, refreshing.

    This has managed to scare my mother

    We use bottled water as it tastes better than tap water ... and part of the problem is who knows what's in that ... and it's easier to put in the fridge in summer as she needs a good supply of chilled water to keep her cool. The filtration jugs that we've tried are useless and we go through filters like... er... water.

    I feel that this has been presented by the news in general without any balance. I mean, even getting out of bed in the morning is a risk. I wonder how much plastic is in my milk bottles, but there are issues with alternatives as well.

      Re: This has managed to scare my mother

      I use bottled water for all drinking and cooking (the tap water is from a well and it's not great). I'm not overly worried about plastics in the water as there are many worse things in my food (while I eat organic meat now, I grew up with meat stuffed full of antibiotics and maybe the odd defective prion or two). I take comfort in thinking that the water I'm drinking has been through a few humans, thousands of animals, and the odd I'm just another meatsack in the chain of life. It'll go in as tea, come out as pee, and continue its journey.

        Re: This has managed to scare my mother

        Here in winnipeg, canada our tap water is soft and pretty high quality (about 120-160ppm TDS, 7.6pH) but the pipes in the city are all too old, break and leak every winter. So you randomly get sick off it, and bad smells. The city's warnings and supply of "portable potable water" trailers are usually late in the game and insufficient to cover the affected areas. I installed an RO unit and pressure vessel for drinking water and very happy with that. Top quality ice for sure.

        AFAIK our canadian meat is not allowed to be fed antibiotics or hormones.

    PET is easy to spot at any size.

    Relative purity

    If the water filtration plant floods the water with PA nano particles, the relative amount of other impurities/garbage goes down.

    1. The Indomitable Gall

      Re: Relative purity

      No, that's not relative purity, really... it seems a lot like absolute purity to me, because you're doing a one-dimensional measure of "how many impurities does it have", with no concern to what they are.

      Water that's swimming with bacteria is relatively purer than water containing nano-plastics from one point of view: the consumer can just boil the bacteria-laden water before they drink it, but there is no consumer tech to remove microplastics.

      Companies have not necessarily reduced overall risk -- they have eliminated known problems that have had known solutions for generations, and they've introduced new problems with no known solution.

    Should have tested beer

    Back in Cobbitt's day he recommended (small) beer over tea (an anathema), milk or water.

    I wouldn't be surprised if traditional beer making as described in his A Cottage Economy somehow removed (flocculated?) these nano/microplastics from the final product.

      Re: Should have tested beer

      There are fining agents (substances that a brewer can add to beer in order to help clarify it) that are basically powdered plastic. The idea is that the plastic drops out (flocculates) and doesn't make it into the finished product, but it attracts some other kinds of particles on the way down, so they are removed as well.

    Well, lets go back to refillable (or recyclable) glass bottles. Jeeze, nothing is more refreshing than ice cold beverages in chilled glass bottles.

    Glass can be cleaned and sterilized, unlike plastics, so it can be reusable. It can also be remelted and used to some extent. Glass is probably the safest thing to use. Unfortunately it's weighty though.

    Pain in the ass, but we still take glass wine, liquor and beer bottles back for deposit. Cans too, but fewer people bother with those, they tend to just go in the recycle bin unless there's a lot of them to justify a trip. They'll give you a few cents for plastics too, like plastic liquor bottles and the liners from those wine boxes.

    For that matter, aluminum cans could be used for bottled water too. They are recyclable for sure, one of the most valuable recyclable materials. However, they need to find other plastics to line them with. (I think currently it's polycarbonate which can release BPA... "bisphenol-A". I don't know how much of a concern it really is in trace amounts, but it's pretty frowny these days)

    I'm 60 and I probably don't have to give a shit. I might drink one bottle of water a week (if I go on a car trip... otherwise we have very good tap water here) but I'm not liking what I'm hearing about PET bottles now.

    1. John Brown (no body) Silver badge

      All that recycling is wonderful. I still use a plastic bottle. Well, two actually. One of them is quite new, less than a year old, because one day last summer I forgot to take the 10-15 year old bottle with me. I rinse them out and fill them every day, leaving them in the fridge overnight ready for another re-use. I guess one day they will be recycled. But re-using is the primary thing. I think my primary water bottle is a 750ml Volvic Sport, the ones with the flip cap/nozzle, but the label deteriorated and disappeared many years ago :-) The previous bottle was a similar type, but eventually the flip cap hinge snapped. I probably got 10 years out of that one too. I'm not being especially "green" or conscious of being eco-friendly etc, just object to the ridiculous cost of buying a bottle of water. I've probably save £100's if not £1000;s over the last 20-30 years by refilling from the tap :-)

      I suppose if I should have any real concerns about re-using that bottle for so many years, it's how is the plastic holding up and am I getting even more micro-particles now than I used to.

    2. Ourshug

      Yes but no, it ain't ever going to happen.

      Truck/lorry trailers are already load & weight limited with any/all liquid beverages. You want to add 150 - 200g to every 500ml <10g PET bottle and cut the load down by another third...

      So unless trailers double their load carrying capacity or manufacturers half the loads and double their transport cost.

      Nope, not gonna happen ever..

    Plastics are everywhere

    They are found in the middle of Antarctica, at the bottom of the ocean, and in rainwater. Therefore they are already in all water you drink at this point at some level.

    So rather than worrying about drinking out of a plastic bottle, we should be figuring out what those plastics are / will be doing to us and the environment. Because even if we quit using plastic tomorrow, this stuff is likely to be with us at least through the lifetime of anyone alive now including those born five minutes ago (and I'll bet if we look closely they were born with some level of plastics in their blood)

    If they are doing bad things to us, it is too late to remove them from the environment. Instead we have to concentrate on figuring out ways to mitigate the negative effects.

  13. jmch Silver badge

    "even if we quit using plastic tomorrow, this stuff is likely to be with us at least through the lifetime of anyone alive now including those born five minutes ago "

    Far longer than that actually. Plastic takes hundreds of years to break down, and it actually simply breaks down into smaller and smaller particles, hence the proliferation of micro and nano particles. There are some interesting prospects of developing certain types of bacteria that feed on plastic, but the only way to be free of plastic waste is if such bacteria were ubiquitous (and that in turn means the lifetime even of in-use plastics would be severely limited)

  14. PB90210 Bronze badge

    I think it's the Law of Unintended Consequences...

    A while back I went to pick up a plastic bag containing old documents, only for it to disintegrate in my hands.

    Back in the '80s folks were complaining that plastics were being dumped in landfill that would take centuries to break down and people came up with biodegradable plastics as the answer... now the stuff breaks down in decades into microparticles...

    And now we have starch-based plastics that are 'compostable' but have to be kept separate from domestic rubbish...
