After sampling Arthur St tank water on Tuesday, an Adelaide laboratory has confirmed the presence of Escherichia coli in a proportion of South Hobart tap water.
A Boil Water Alert is in place for a small region in South Hobart meaning residents will need to boil drinking water until further notice. This includes water used for brushing teeth, washing and preparing food or drinks, baby formula and for making ice.
The health notice states that unboiled water can be used for showering and bathing, though you will need to avoid swallowing water and toddlers and babies should be sponge bathed. Dishes and clothes can still be washed in the water, provided they are air-dried before use.
Tests are currently being undertaken to determine the cause of contamination, with results coming back from the Adelaide laboratory, tomorrow at the earliest.
If you experience symptoms such as vomiting, diarrhoea, cramps or feeling unwell, contact your GP as soon as possible.
For now, you can access the affected region of South Hobart by reading the TasWater public notice here.
