In this country, the drinking water purification system used by maintenance facilities is designed to protect us from typhus, cholera and other diseases. While they have controlled the outbreak, except for some cases of cryptosporidiosis, parasitic infections of the digestive tract, the tactics they use leaving something desired.
Every drinking water purification system can produce something "satisfying". Whether it's healthy or not for long-term consumption is another question completely. In an emergency situation, you can use household withers to clarify and disinfect, but you don't want to continue using it regularly. You want something healthier and better taste everyday use.
Drinking water purification system varies. Public facilities can use wire mesh, flocculation, UV and / or chemical disinfection, reverse osmosis filter water softening agents, ultrafiltration, deionization, carbon care or any combination. And, still, there are other methods used to overcome certain contaminants.
No matter how good the public water purification system is possible, there are certain problems that they cannot fix. Chemical contaminants are not easily removed and often end up in the final product.
The number of drugs and hormones has been found after testing. Bacterial cysts (something like eggs) float along the way and cannot be removed by one of the drinking water purification systems mentioned above. These cysts caused more than 100 deaths in Milwaukee during the Cryptosporidiosis outbreak.
