Key public health messages following the recent earthquakes in Nelson and Marlborough
Boil drinking water if the supply has been damaged and/or boil water notices issued. There has been damage to the Seddon and Ward supplies. Both Seddon and Ward supplies are on permanent boil-water-notices, however earthquake damage may have increased the risk of biological contamination at this time.
Private reticulated water supplies and individual household supplies may also have been compromised by earthquake damage and so it may be appropriate to boil water as a precautionary measure until normal treatment and/or supply has been resumed.
- Bringing water to the boil is sufficient to kill bugs.
- Boil or treat all water from taps and tankers before drinking, brushing teeth or using in food preparation.
- Water needs to be boiled even if the smell or taste of chlorine is present.
- If you cannot boil water, treat it by adding 1 teaspoon of plain (non scented) household bleach per 10 litres of water and leave for 30 minutes.
- Employers should also ensure their staff are only consuming boiled/bottled water at work.
