THOUSANDS of Yorkshire households were warned not to use tap water at the weekend because of contamination.
Around 3,600 households in the South Yorkshire communities of Thorne and Moorends have now been told they can use the tap water providing they boil it first.
Yorkshire Water is investigating an industrial estate thought to be the source of the high levels of bacteria.
It said: “The protection of public health is our number-one priority and we will only lift the new advice to boil the water as soon as it is safe to do so.
“We will also continue to distribute bottled water directly to the homes of our vulnerable customers.”
“We are continuing to identify the exact cause of the contamination, with investigations focused on a local industrial estate in the area.”
