Christchurch advised to chlorinate water to avoid contamination

The city of Christchurch is likely to have chlorinated water within two months because some of the city's groundwater wells could be vulnerable to contamination. Canterbury Medical Officer of Health Alistair Humphrey has advised the city council to temporarily chlorinate the water. Fans of Christchurch's water who RNZ spoke to are none too pleased. Christchurch City Council is to vote on the issue on Thursday. Dr Humphrey tells Guyon Espiner it's expected to go ahead.
