Sediment, chlorine and bacteria are three of the main contaminants that can be found in drinking water. They can cause health problem if the concentration of these contaminants is too high or if you are exposed to them for a long time.
What are the effects on our health ?
The sediments
Sediments are solids particles found in water sush as plants fragments, soil or minerals. These contaminants can settle to the bottom of reservoir or lake. This is how they are carried into the pipes that distribute drinking water.

Chlorine
Chlorine is a common disinfectant used to kill germs and bacteria in drinking water. It can cause minor health problems such as eye and respiratory irritation. But it can also cause more serious problems such as allergies and skin irriation.
Some researchers have also linked chlorine exposure with increase cancer risk.
Bacteria
Bacteria are microorganisms that can be found naturally in water. Some bacteria are beneficial for health but others can cause diseases.
Bacteria dangerous for human health include Escherichia coli and Legionella pneumophila. These bacteria can cause intestinal infections, pneumonia and others serious diseases.
Warning :
It is important to note that these contaminants are not always present in drinking water and the majority of drinking water systems are designed to remove or reduce them to safe levels.
However, it is possible that leaks or debris in pipes or tanks can allow these contaminants to enter the drinking water.
Therefore, it is important to regularly monitor water quality and follow « boil water » advisories issued by local authories if necessary.
