Authorities are apologising after contaminated tap water left dozens of Darfield residents stricken with diarrhoea and vomiting.
The Selwyn District Council will review its systems after more than 125 Darfield residents were struck down by gastroenteritis after drinking contaminated water.
The announcement comes after Canterbury District Health Board medical officer of health Alistair Humphrey said the council needed to ''wake up to its responsibility'' and address its recurring water issues.
Humphrey said more than one barrier had failed, resulting in the ''serious outbreak''.
''Intensified farming now means that a lot of water is contaminated with animal faeces, especially the Waimakariri after heavy rains. Secondly, the chlorination of this heavily contaminated water fell short of levels required to make it safe.''
He said the importance of protecting water from source to tap was ''sometimes lost in political imperatives''. Stuff, August 29
