Toxic algae a threat to Sweden’s water supply
High levels of toxic blue-green algae, which has thrived in this summer’s extreme hot weather, is making it more difficult to secure clean drinking water.
Caroline Dirks, a chemist with the Swedish Food Administration, tells Radio Sweden that large amounts of cyanobacteria found in algae can be difficult to filter out from the water supply.
“There is a possibility that it can end up in the drinking supply because we produce a lot of our drinking water from surface water and if there is a severe algae bloom then there is a risk that it can enter the drinking water process,” she says.
Dirks recommends that drinking water producers carry out risk assessments and take measures to be prepared to face the algae threat.
