They are pretty lax on regulating bottled water, so sometimes your tap water might be safer, as the article stated. The sources of bottled water may be misleading and not as pristine as they appear to be. As for tap water, there are expensive filters you can put in your house to filter all your water in your house.
I actually just tested my tap water at home with a cheap home test. It passed the two tests I was curious about (pesticides, lead) but the test strip wasn't as obvious as I would have liked on the pesticides.
I myself am drinking distilled water. We also have a reverse osmosis water filter for our fish, they love it. If anyone heard distilled water is harmful, I just went into this debate on another board, so I can post helpful links to set your mind at ease.
We get the 5 gallon water jugs, and I fill a Thermos full for my husband so he can have cold, distilled water at work, and I myself drink out of my sports bottles. The picture of the 9 out of 10 water bottles piling up as garbage taking 1000 years to biodegrade makes me very sad.
Thanks for sharing this article, I'm always interested in learning more about water.
