Think your tap water is safe? You won’t believe what could be floating in it.

That crystal-clear glass of water from your kitchen tap might look pristine, but it’s basically a chemistry set wearing a disguise. We’ve been conditioned to equate clarity with purity, assuming that if we can see through something, it must be safe to drink. It’s like judging a person’s character by their appearance – sometimes the most dangerous things come in the most innocent packaging.
Your municipal water supply works hard to keep the really scary stuff out, but plenty of unwanted guests still manage to crash the party. The truth is, your tap water has more passengers than a rush-hour subway car, and most of them didn’t buy tickets.
