Yorkshire Water has completed its investigations into the water quality issue in Thorne and Moorends in Doncaster, where a Boil Water Notice has been in place since Saturday - E.coli and a related group of bacteria were found in samples that were collected during the incident.
The utility said it was confident it has identified the source of the bacteria and immediately isolated the source from the water network. Once the investigation found the source, which is external to the Yorkshire Water network, several physical barriers were put in place to stop this source from contaminating the water network in Thorne again. Yorkshire Water said it does not wish to name the source at the moment .
The bacteria is routinely tested for by water companies - once the bacteria was found Yorkshire Water launched a full investigation into the cause and issued a ‘Do Not Drink’ notice to local residents, which was later changed to a ‘Boil First’ Instruction.
A full list of postcodes that are still required to boil water before using for drinking and cooking is in place on the Yorkshire Water website this morning.
Charlie Haysom, Director of Service Delivery, said:
“As soon as the bacteria was found we responded by launching a full investigation into the cause of the problem. We’ve now put a permanent solution in place so this incident cannot happen again from this source.”
“The sample results have improved significantly, but we need them to be completely clear before we can lift the boil notice. Residents in the affected area must continue to boil their water until we tell them otherwise.”
The water company has said it will issue "good will payments" of £30 to customers in Thorne and Moorends to thank all affected residents for their patience.
Yorkshire Water said the Boil First order is still in place and will remain so until at least Thursday. It has received some reports of people making bogus phone calls claiming to be on behalf of Yorkshire Water saying that the order has been lifted.
