Water pollution is the contamination of water sources by substances which make the water unusable for drinking, cooking, cleaning, swimming, and other activities
Where does water pollution come from?
sewage and waste water
How do we detect water pollution?
Water pollution is detected in laboratories, where small samples of water are analysed for different contaminants
animals
