Question: Is a lot of our water we drink is polluted

Luckily for us here in Ireland, our drinking water is generally considered safe and not polluted. In some parts of the country, people are told to boil the water before they drink it to make sure it is safe. Unfortunately in other less developed parts of the world, water pollution is a really big problem. It’s really important that scientists keep working to find new solutions to improve water quality to make sure it is safe for people to drink. As part of my research I’m trying to develop devices that tell people whether water is safe to drink or not.
