asked the Secretary of State for Wales, in view of the fact that crude sewage is being discharged into the River Dee at Llangollen, Clwyd, and will continue to be so discharged, as a result of the failure of the Welsh National Water Development Authority to implement phase IV of the Llangollen Chapel Street sewerage scheme, whether he will take immediate steps to investigate this situation on health grounds.

This is a matter for the Welsh National Water Development Authority. It has carried out tests and informs me that there is no evidence that there is a public health risk involved.
