since returning to work at a pre-school after the summer holidays we have noticed a strong taste of chlorine in the drinking water. some days the water is undrinkable but is it dangerous
The chlorine in the water supply will always be within safe limits. There are many water filter jugs available that will remove most of the chlorine by using a carbon filter. Chlorine evaporates quite quickly from an open container. Filling an ordinary jug, and letting it stand for a few hours, will get rid of a lot of the chlorine.
