Water is a critical element of any survival gear, so I pay special attention when there is news about treating and storing it.
That why I was absolutely stunned to read this article.
Years ago I used bottled waters in my cache. I would cycle them in and out, but only about every 3 years. As I would do that, I would always notice how the old bottles felt flimsy and thin after pouring the water out. I always thought the plastic probably broke down and evaporated into the air. It turns out the reason that was happening is because I was pouring a large portion of the bottle out with the water! The chemicals in the bottles were actually leaching into the water.
Now as bad as that sounds, the chemicals in plastic bottles are especially bad for you. BPA, the nastiest chemical found in common plastics, actually mimics the hormone estrogen. So yes, using old water bottles for storage or repeated usage can increase estrogen in your system. It can also cause cancer, weight gain, and infertility. The hormone confusion it causes can also accelerate puberty and alter growth patterns in children.
So, as we’ve written about repeatedly, be careful about how you store your water. If you have to use bottled water, change the bottles AND the water yearly. Use larger plastic containers that do not contain BPA for long-term storage. Keep a variety of stored sizes and weights so that all members of the family can help transport water.
Remember our on-the-fly water treatment methods so that you can get clean water wherever you are and no matter what the conditions are. And don’t forget to keep your water safe from looters.
