Good quality drinking water is one of the great blessings we enjoy here in Australia. Anywhere we go, we can expect to turn on a tap and have cool, drinkable water instantly.

And the results, in some places. Have been less than ideal. One of those scientists, Senior Lecturer in Environmental Science Dr Ian Wright, joined us over the phone.
