A study was carried out on 258 rivers in 106 different countries. What did they have in common? That they are all polluted with residues from the pharmaceutical world to levels that are dangerous to humans.

This very comprehensive and factual international study shows that this pollution affects more than a quarter of our planet's rivers. And that this pollution is present even in remote places such as Antarctica or Amazonia.

The drug residues found, such as antibiotics, antidepressants, anti-inflammatories and others, come both from the care given to people living longer and longer and from agriculture, which uses certain substances to treat farm animals.

Ecosystems are affected, with more or less deleterious effects, but so is human consumption. Wastewater treatment plants are unable to filter these substances because they are not designed to eliminate them, so they are allowed to pass through, and some of these molecules undoubtedly end up in our tap water.

A good idea to purify your water: use a Berkey® filter, designed to eliminate many chemical molecules from the pharmaceutical industry.
