How can water be contaminated?

ANSWER

Water can be contaminated in several ways. It can contain microorganisms like bacteria and parasites that get in the water from human or animal feces. It can contain chemicals from industrial waste or from spraying crops. Nitrates used in fertilizers can enter the water with runoff from the land. Various minerals such as lead or mercury can enter the water supply, sometimes from natural deposits underground, or more often from improper disposal.
