Chlorine is a poison which in moderated doses is used to treat water for swimming and drinking. It kills many germs which might otherwise make people sick. It also gives the water a blue tint, which is why the water in swimming pools appears to be blue. A glass of chlorinated water held against the light will be blue, while water untreated with chlorine is clear.
