A pollution incident has occurred following a leak from a heating oil tank located at the former Ardwyn School in Welshpool, Powys County Council has said.
The incident has resulted in the migration of an unknown quantity of oil from the site which is known to be impacting properties within the town. The council said that the landowner is aware of the situation and is currently commencing actions to make the site safe.
The leak has now been stopped.
The Mid and West Wales Fire and Rescue Service crew from Welshpool responded to the site on Wednesday and today (Thursday). Crew members have used absorption pads and granules to remove surface oil and to prevent further contamination of the local water supply.
Further investigations into this pollution incident are ongoing by Natural Resources Wales and partner organisations.
If you are experiencing the smell of heating oil (kerosene) inside your property you are advised to, where possible, ventilate the impacted rooms.
If your water supply is affected (by taste or odour) you should contact Hafren Dyfrdwy on 0800 0858033 for advice.
