A serious pollution incident led to a 3km oil slick near the Potteric Carr Nature Reserve, Doncaster.
Environment Agency officers have contained the oil slick with oil absorbent booms and pads, and are now starting the clear up process. As oil floats on the surface of the water, these booms prevent the oil from spreading and the pads soak it up, without interfering with wildlife or the flow of the river.
Whilst the exact source of the oil has still not been established, it has been narrowed down to the nearby Balby Carr Industrial Estate area. There is no further oil coming from the drain, but protective measures will stay in place over the weekend in case the forecast rain washes more through the system.
