The first series of tests is seeing the end of another boil water order for thousands of Saint Johners will be taken today.
The boil water order remains in effect for residents east of the Reversing Falls bridge after strong winds and heavy rain stirred up turbidity levels.
The order will be in place until at least Sunday night.The city is advising you to boil your water for at least a minute before drinking it.
It is safe to shower or have a bath and wash dishes but, the water must be hot and soapy.
