Ottawa Public Health lifted its boil water advisory affecting residents of more than 700 homes in the Carp area.



The precautionary measure was due to a drop in pressure in the town's communal well system.



People in the affected area were asked to bring drinking water to a rolling boil for at least one minute before using it for drinking, making juice, ice and infant formula, or any other food preparation.



The water was fine for uses such as cleaning or showering, the city said.



On Friday morning, an official release said tests show the water is again safe for human consumption. No other tests are required by households.



However, residents are advised to run the cold water tap for at least one minute for the first time, before drinking it as usual.
