Hawke’s Bay laid low with gastro – In the News

Posted in In the News on August 18th, 2016.

Thousands of people in Havelock North have been laid low with gastroenteritis in the past week following a contamination of the drinking water supply, thought to be campylobacter.

He said the most common contributing factors to such contamination events were untreated or inadequately treated water supplies.

Massey University’s Professor Nigel French told media that the incident showed even secure groundwater could become contaminated, highlighting the importance of testing and treatment especially after high-risk events such as heavy rain.

Radio NZ reporter Kate Newton dug through documents and news reports to show that while large outbreaks are rare, waterborne disease is common in New Zealand.

The outbreak isn’t the first in the Havelock North community: last year E.coli was found in a bore about 200 metres from the wells at the centre of the current outbreak. A Tonkin and Taylor report on the 2015 outbreak was given to the Hastings District Council this week, but it was unable to identify the cause of the contamination.

Water treatment engineer Iain Rabbits has been vocal in the media, saying the outbreak could have been prevented if water had been chlorinated. Water NZ chief executive John Pfahlert agreed, calling for an inquiry to consider whether chlorination should be compulsory for town water supplies.
