Water contamination is a public health problem that arises when chemicals (pollutants) are released into surface water, groundwater or groundwater. These substances can come from many elements and are both natural and technological.

Different water contaminations :

  • Pathogens : Pathogens are microorganisms that cause disease: bacteria, fungi, viruses.
  • Pesticides : they are found in soils and groundwater.
  • Metals : they are found in the soil and groundwater: lead, cadmium, mercury, copper, nickel, arsenic, iron, zinc, etc.
  • Volatile organic compounds (VOCs) : they are found in groundwater and rivers.
  • Hydrocarbons : they are found in groundwater and rivers.
    Drinking water is often the most contaminated element. Chemical factories, garbage dumps, aluminum industries, mines and other industrial sources, accumulate pollutants in the environment. These substances can be found in groundwater and even in the aquatic environment.

Drinking water can also be contaminated by a chemical spill or a leak from an industrial facility. Drinking water can also be contaminated with bacteria or parasites from a polluted area, from a farm, or from timber in a contaminated area.

The potential risks are much more serious when the contamination of the water is due to pathogenic microorganisms. Pathogenic microorganisms can be present in groundwater, in the water table, and in surface water.

What are the risks associated with water contamination ?

Contaminated water can cause health problems, damage the environment, and impact the economy. The consequences of water contamination vary depending on the type of substance. Some water soils can be harmful to your health while others can affect the appearance, smell or properties of the water. Contaminated water can also damage crops, cause wildlife to move away from the area and damage infrastructure.

The chemicals can irritate the skin and mucous membranes, cause respiratory damage, damage to the nervous system, and can even cause cancer.

Our bodies need water, we consume a lot of it throughout the day, it is essential that it be as healthy as possible.
