And not a drop to drink (211.6) - Mark's Journal
And not a drop to drink (211.6)
There are so many opinions out there about what's safe for carrying water. Will leaving a plastic water bottle in the car poison my water with dioxins? Will using an aluminum bottle give me Alzheimer's, just like antiperspirants containing aluminum are supposed to? Are "reusable" plastic water bottles safer than the ones you buy by the case already full of water?

Watkins Glen WeekendI love the tip to freeze a half-full water bottle and then fill the other half on the way out the door so you'll have cold water for hours, but is that dangerous, too, as one oft-spread warning suggests?

Mostly, I refill old water bottles again and again. I love the tiny ones that I typically get at blood drives, since in most cases I can put one in a jacket pocket and always have it with me. (In the summer, I go to cons and concerts with cargo shorts. Water bottle in one side pocket, lens in the other.) Am I slowly killing myself?

They officially spooked me off the smaller ones that I liked to use as well.

I'll reuse them once or twice, if at all these days.

I use one aluminum and one glass (like this).

What did our ancestors use?? Perhaps we should be copying nomadic tribes!

"The product you are trying to view no longer exists," says your link.

Our ancestors carried water in dried bladders. No thanks. Leather or oilcloth canteens, for a long time. Then the military-style aluminum canteens I used for camping.

Buddha (below) suggests I needn't worry quite as much about the plastic bottles as I was starting to, but maybe I just need to look for BPA-free containers.

Well, my internet sucks atm, so I'm not going to look for another link -- it's glass & silicone. Hedging my bets. Obviously glass will be "BPA-free".

Despite that, the "gross" factor, they didn't worry about BPAs... or giving themselves Alzheimer's. Meh. It's just ironic the two step forward, one step "progress" of mankind at times.

I prefer drinking water from glass, but I can't take glass with me on the go. I have a few bpa-free cups that I use when I'm out and about. I will cop to carrying 4 disposable bottles with us into the city last week. We refilled them throughout the day. Only 2 of them hit the trash before we left the city, but those ended up in the recycling containers in Millennium Park. The other two went in our home recycling. I sure hope that I'm not going to get cancer from them. :)

I am terribly rough on my stuff and that thick glass incased in silicone has already lasted longer than a year!! It's also easy to clean and fairly light weight.

I'm gonna have to take another look for glass water bottles in the 8-12 ounce range.

That's pretty much what I do... keep refilling them as long as they're useful! Just for longer than a weekend. :-)

Coincidentally, I just read (and have the browser tab still open) a Snopes.com story about this: http://www.snopes.com/medical/toxins/plasticbottles.asp

Bottom line: plastic bottles don't contain dioxins or DEHA, and despite research and testing, DEHA hasn't had enough evidence of carcinogenic effects to worry about even if it was in the plastic. Dioxins, while toxic, are generated at high temperatures (over 700 degrees F), and not by freezing. Cold temperatures (like freezing) reduces diffusion and leaching anyway, simply because cold slows down all chemical processes.

Heat, on the other hand, may be a concern, as elevated temperatures can caused phthalates and BPA to leach out. But how dangerous this is is unclear as well.

So don't worry about freezing or cold water.

I can think of an easy experiment to run, assuming I had a lab with a GC/MS and similar equipment: Get 48 plastic bottles and 48 similarly sized glass bottles (mason jars would work fine). Empty and clean them. Fill all 96 containers 3/4 full with tap water (or distilled, if you so choose). Split the containers evenly between a freezer (at 0F), a refrigerator (at 40F), a shelf (at 68F), and a hot room/proofing box (at 90F). Wait a week. Then use the GC/MS on all 96 samples to determine what the differences are between the samples, especially differences correlated with storage temperature.

Re: No

Thanks. Like you, I'm much less worried about cold than I am about hot. Leaving my water bottles in the car from April through October would seem to be potentially hazardous, thanks to phthalates and BPA if nothing else.

Even the BPA nervousness is overblown at this point. The various panels which have look at most of the BPA research generally mark various health concerns as negligible to minor with the minor concerns generally focusing on very young children and pregnant women. While it's probably not a bad idea to get BPA free containers I wouldn't worry too much.

Dammit, I clicked comments and nothing was there. Now all the people are there. :)

The glass water bottles come in all sizes and are awesome. Sure they have them at EMS. and you'll be helping the environment. Using tons of small plastic bottles is super wasteful IMHO. :-)
mhaithaca From: mhaithaca Date: May 6th, 2013 09:43 pm (UTC) (Link)

That's why I don't use tons of them, and instead keep reusing a couple for months at a stretch. :-) Carrying around glass sounds inconvenient and potentially dangerous.
helianthas From: helianthas Date: May 7th, 2013 12:03 pm (UTC) (Link)
1. Not dangerous.
2. Why not just buy a reusable plastic one, then? (Personally, I love my platypus that folds up easily into my purse when it's empty...)
mhaithaca From: mhaithaca Date: May 7th, 2013 12:08 pm (UTC) (Link)

Thanks, I like their web site. I might have to see if I can find a small-enough Platypus.

Bugs ?

I don't re-use plastic bottles. If I'm on a trip and need water along the way, I'll buy and consume a plastic bottle, but not reuse the bottle.

The thing that always concerns me about leaving *any* water in any kind of container for any period of time, and then re-using the container, is germs. I don't think any one's drinking water is exactly sterile, and then secondary use of any bottle without sanitizing it seems like it'd invite germs to grow. Yummm, germ soup ? Or am I being un-necessarily concerned ?

Re: Bugs ?

I'd worry more if they were other people's germs! My own are probably fine in the short term, and I do periodically rinse out the bottle and cap in very hot water. I'm sure you could also use a weak bleach solution, but at that point it seems like it's time to throw out the bottle.

Re: Bugs ?

Ahh, well, true - probably OK If it's just my germs ... lol ... I do use bleach water to rinse out the metal water thermos things around the house, seems wise.

I'm SO bad about this. I probably use BPA free bottles like the contigo ones about...50-60% of the time, but I definitely refill plastic water bottles a lot. Probably too much, even knowing that snopes says the dioxin threat really isn't that hardcore...
