Pollution de l'eau

Disposition de débris de dragage, Miramichi, mai 1981La pollution de l'eau est causée par des déchets industriels et institutionnels ainsi que par d'autres matières nocives ou inacceptables.

À mesure que l'eau parcourt son trajet dans le cycle hydrologique, elle entraîne divers contaminants présents à la surface de la Terre. Lorsqu'elle est absorbée dans le sol, elle peut libérer ces contaminants en chemin. Lorsqu'elle s'écoule dans un cours d'eau ou un puits, elle peut transporter ces contaminants dans votre maison.

Les activités humaines peuvent modifier la qualité et le volume de l'eau qui s'écoule dans un ruisseau ou sous le sol.

La présente section renseigne sur les causes et les effets de la pollution de l'eau et les types de pollution de l'eau qui sont particulièrement préoccupants au Canada.
