Truth be told, it tends to be hazardous; another investigation from the Environmental Working Group (EWG) discovered disturbing dimensions of chromium-6 (the cancer-causing "Erin Brockovich" compound) in drinking water that about 200 million Americans drink, from every one of the 50 states.
Chromium-6 is a long way from the main water poison. Our water can contain differing dimensions of different contaminants, for example, arsenic, lead, and mercury.
What are you expected to do? You realize drinking water is a fundamental solid propensity, connected to everything from getting in shape to helping weakness. So you need a great deal of it, yet getting the best stuff probably won't be as basic as purchasing the fanciest-looking jug at the market.
First of all, filtered water isn't really any better for you, and it comes at a lofty money related and ecological expense - Americans burned through $11.8 billion on filtered water in 2012, and discard in excess of 60 million of those plastic jugs multi day.
