Holy Hannah, did you know there’s drug residues (metabolytes) in the groundwater in every village town and city on this planet??
To avoid taking in other peoples drug residues, I would highly recommend a water filter/purification system that will ensure the water you are taking in has been absolutely combed clean of drug metabolytes.
What causes drugs to end up in our tap water? Drugs are used every day by millions of people. Billions in fact. Those drug residues are poisons, and the body tries hard to shed them. It cannot shed all but tries. Therefore the residues end up via the toilets and sinks and the industrial waste that gets dumped right into the municipal water system. I used to sell water purifiers and there are many articles and videos you can catch on youtube or elsewhere on this subject.
I suggest you arm yourself with all the information available out there on the subject of drugs in your tap water, and then protect you and your family from continuing contamination by removing the residues completely with an effective water treatment system.
And then get on all the committees or sub committees or public awareness group mailing lists that you can and see how you can add your voice in protest to this problem. Pharmaceutical companies are poisoning our groundwater. Illegal drugs came from pharmaceutical labs in the first place, so these “orphans” of the pharma industry are part and parcel of the problem.
Don’t want drugs in your tap water? Get involved. For your own sake, and that of your children, and their children’s children.
This problem won’t go away by itself.
