Top 10 Contaminants in Tap Water

Here are 10 of the top contaminants that can be found in your tap water. Beware... what you read next may change your perspective forever!

Personal Care Products
Antibiotic soaps, perfumed products, products containing microplastics, and other chemicals/contaminants go down the drain and then can be found in water supplies.

Most arsenic in drinking water comes from natural rock formations. As water flows through these formations, it can dissolve arsenic and carry it into underground aquifers, streams, or rivers that may become drinking water supplies. Long-term exposure to low levels of arsenic in drinking water is known to cause cancer, thickening and discoloration of the skin, problems with blood vessels, high blood pressure, heart disease, nerve effects including numbness and/or pain, and more...

Microorganisms, Bacteria, and Viruses
Honestly, This requires a whole other list… But SOME of the harmful bacteria found in public water include E.Coli, Hepatitis A, Salmonella, Giardia Lamblia, and Cryptosporidium. Drinking water with disease-causing bacteria, viruses, or parasites (collectively called pathogens) will make you very sick. Oh, and here’s a not-so-fun fact- According to the World Health Organization, at least 2 billion people globally drink water contaminated by feces.

Nitrate is a compound that is formed naturally when nitrogen combines with oxygen or ozone. Nitrogen is essential for all living things, but high levels of nitrate in drinking water can be dangerous to health, especially for infants and pregnant women.

Fluoride is produced synthetically for use in drinking water. Water authorities add fluoride to “prevent tooth decay.” The risks outweigh the benefits greatly. Firstly, the fluoride only makes contact with your teeth for a few seconds but remains in your body for much longer. Fluoride can lead to thyroid problems, neurological problems, acne, reproductive issues, and much more.

Lead levels in drinking water depend on many variables such as the pipes in which the water travels, the corrosion on the pipes, the water’s acidity, etc. As you may know, this toxic metal causes damages even in low doses.

This powerful oxidant, a reactant that removes electrons from other reactants, is used to treat water and control microbes. Chlorine can be absorbed by drinking and also while bathing. Chlorine severely dries out hair and skin and can irritate your eyes, nose, etc.

This liquid metal can be found in natural deposits, discharge from factories, landfill runoff, and others. Being exposed to high levels of mercury over time will cause kidney damage.

These synthetic chemicals found in prescription medications make it into the water stream by poorly controlled facilities and improper disposal from individuals.

Herbicides enter the water stream by accumulating in public soil, and water sources. They usually enter our water supply through irrigation or rain runoff. Atrazine, a common herbicide used on golf courses, can interfere greatly with the body’s hormonal activity and reproductive organs.
