People in general like to moan and grown over the water issue and want any excuse they can find to not make their own. Like your story, those that make their own, KNOW, once they KNOW, other polluted metalic water makes them ill to think about drinking it. This is why pop and carbonated flavored drinks are so common, add sugar to the most toxic water and children will live on it.
People are so miseducated about sugar and don't realize the traps their food manufacturers have caught them in.
