Common Toxins Found In Your Tap Water

We are lucky to have access to water from the convenience of our tap and we are lucky to have the resources to dig deeper and educate ourselves about the quality of this water. And most findings are not too pretty. So if you thought your tap water was clean – think again.

Here are the most common toxins found in your tap water:


This is added to sanitize drinking water and to kill bacteria and viruses. It can cause skin irritation, dry scalp and hair and inflammation of the respiratory system further emphasizing asthma and other chest-related conditions.  In high amounts, Chlorine has been linked to cancer as well as risk pregnancies.


This is an ion of chlorine and may find its way into drinking water through water contamination from road salt and other factors. High amounts of this equal high amounts of sodium in our bodies.


People get about a third of the lead in their bodies from drinking water that has passed through lead pipes. Lead pipes were commonly used in the past for plumbing and may leak toxic lead residue that may affect your immune system, teeth and bones. Over 15% of distribution pipelines in North America are over 100 years old!


This comes from iron pipes or water seeping from soil and rock. While iron may not pose health hazards it can result in staining (rust) and bad tasting water.


This is a toxic chemical that can contribute to an increased risk of bladder, lung, and skin cancers.


This comes from corrosion of copper piping and in high amounts can cause stomach discomfort, vomiting and diarrhea.

Hydrogen Sulfide

This forms by the decay of organic matter – usually not a health concern but results in awful tasting water.

And last but certainly not the least group of contaminants that end up in your water are volatile organic compounds (VOCs for short).

VOCs are a class of chemicals that evaporate or vaporize quickly (which makes them volatile) and they contain carbon (which makes them organic). Hundreds of VOCs have been produced for use in consumer products, including gasoline, dry cleaning solvents, and degreasing agents. When these are improperly stored or disposed of VOCs can contaminate household water.

What’s worse, VOCs may also enter your water supply through the chlorination process. Chlorine reacts with many of the organic materials in water and can form VOCs known as chlorination by-products. And Chlorine is one of the main ingredients used by nearly all water treatment facilities.

Drinking and bathing water that contains high levels of VOCs can hardly be called healthy. Contaminated water can cause a wide range of illnesses, as well as specific and non-specific symptoms.

For instance, VOCs like chlorinated solvents are easily absorbed through the digestive system and the lungs. Once inside a human body, VOCs accumulate in the liver, kidneys or fatty tissues. High amounts of them can cause symptoms like dizziness, headaches, lack of concentration and forgetfulness, and they can affect the heart.
