Safe drinking water back in Östersund?
Water in the northern Swedish city of Östersund will soon be bacteria-free after several months of contamination and thousands of cases of stomach illnesses. This is thanks to an ultraviolet filter placed in the water treatment plant.
A labaratory in the US has analyzed samples of contaminated water that have passed through the filter and confirms that this leads to decontamination.
All water pipes will have to be rinsed with clean water before tap water can be considered safe to drink again however and this is estimated to take a week.
