No One Knew How Dangerous Lead Was
It is an unfortunate reality that lead continues to be an issue in our water supply system. However, it used to be worse in the past. When bathtubs and water systems were originally built, they used lead. Back then, people did not know that the metal was dangerous. Water supplies continue to be tainted with lead, but filters and other tools make it possible to keep them clean. It has resulted in fewer people falling sick from using tap water for bathing or drinking.
