Lead in water – a substance hazardous to health and how to deal with it

How does it get into my drinking water ?

Before 1973 the substance was often used as piping material. Only then were alternatives preferred for new buildings. Lead can get into the water if left standing for a long time. It dissolves there. If you live in a house, whether renovated or not, that was built before 1973, lead could be present in your tap water . However, if your house has been renovated, this is less likely. If your house was built after 1973, you generally don't have to worry.

The general rule is that the substance gets into water if left standing for a long time. This is why household appliances, such as coffee machines, can also be affected. Lead can also accumulate in faucets.

How dangerous is it?
