No biggie really considering the amount of drugs, chemicals and contaminates found in city tap water. Many active drug metabolites pass directly through the liver and remain active in urine, even after the city water has been purified. This is why girls breasts have gotten so big and many men are pussifing before our eyes. Birth control pills are the main reason for this.
I won't bother to mention the radioactive cesium and other nasty things in our water and food supply directly attributed to the Fukushima meltdowns.
