The town of Birch Hills, SK has been advised to boil its tap water because algae blooms are causing high turbidity within the system and discolouring the water.
According to town administrator Tara Gariepy, this is a seasonal issue,"although, this year the water seems to me to be more discoloured but have less of an odour than in previous years."
The town's water comes from two reservoir ponds on the outskirts of town.
"This is a historical problem," says Rahoul Hampul, health inspector for the Saskatcehwan Water Security Agency in Prince Albert. "There are algae blooms in the raw surface water. The hot temperature we are experiencing is also causing stratification of the ponds whereby the upper layers are warmer than the deepest layers creating a churning of the water which brings up the sediments."
The precautionary advisory affects about 450 residents as well as a number of tanker trucks who use the town's fill station.
Hampul says that the town is currently using an aeration process to help remedy the situation but its water system is due for an assessment by the Water Security Agency next year which will determine if a new treatment plant is required to solve the algae issue in the longer-term.
