I am in the affected area, what should I do?
If your drinking water comes from a private bore, there are several steps you should take for your safety:
- Boil your drinking water and water used for hygiene purposes for at least one minute before consuming. This will treat any E.coli that may be in the water. Learn more about boiling water.
- If you have a bottle-fed infant under the age of six months, use an alternate water source or use bottled water to make their baby formula. This will help to ensure your infants' safety if there are high levels of nitrate in your water. Learn more from the Canterbury District Health Board.
- Arrange for your bore water to be sampled and tested for E.coli and nitrate. Find information on companies who provide this service. Learn more about the correct sampling procedure.
I have consumed unboiled water, what should I do?
If you are experiencing any symptoms such as diarrhoea, vomiting or a fever, consult your general practitioner at any time of the day or night.
How long will this notice remain in place?
You should continue boiling your water until we further advise. You should boil water until such time as your water is tested and is determined safe. Please note that as your water comes from a privately owned well, you are responsible for testing it regularly. This should happen at least four times a year for E.coli and once a year for nitrate.
