Chlorine: not agent of the devil

One of the world's leading water contamination experts says New Zealand is vulnerable to another drinking water crisis because of a lack of chlorination. Professor Emeritus of the University of Alberta, Dr Steve Hrudey, prepared a 50-page analysis on the 2016 contamination of Havelock North's public drinking water on behalf of Water New Zealand. He says a failure to recognise close calls and complacency were a major factor in the crisis, as well as the avoidance of chlorination. Dr Hrudey is out in New Zealand speaking at the Water New Zealand Conference, starting next week.
