BBC – Lancashire water supplies declared safe
People in Lancashire who had been boiling their drinking water have been told supplies are back to normal.
Up to 300,000 homeowners could not drink tap water for more than three weeks after cryptosporidium, a microbial parasite, was discovered.
Supplies to the last 50,000 homes have now been declared safe to drink and residents no longer have to boil their water, United Utilities said.
The bug was found at a treatment works near Preston on 6 August.
