Skellefteå works to make its water drinkable

The northern city of Skellefteå is getting three ultraviolet light machines on loan to help clean its tap water, which officials suspect is contaminated with a stomach bug.

The UV equipment is reportedly the most effective way to kill the parasite, Cryptosporidium, which can cause diarrhea and stomach aches. Some six-thousand residents there have reported that they suffered from stomach maladies in April.

Officials believe the drinking water is contaminated by waste water, though they are still waiting for tests to confirm this.

Swedish Radio news reports that the machines should be ready to install by next month at the latest, but that residents will probably still have to boil their drinking water for a number of weeks afterwards.
