Ossett Spring Mill Ponds polluted by mystery leak
A mysterious flow of oil or diesel in a stream in West Yorkshire has led to a warning for children and pets to be kept away from the leak.
The pollution of Spring Mill Ponds in Ossett was first noticed in December.
The Environment Agency (EA) has searched the nearby Milner Way industrial estate and around Flushdyke but has not found the source.
A series of booms and absorbent pads have been used to prevent the pollution from being carried downstream.
The EA believe the pollutant could be red diesel, and not waste oil, so the leak could be in a fuel system rather than a deliberate disposal of waste.
The source of the leak could be some way from Spring Mill Ponds especially if the pollution has entered the drainage system or the water course.
Councillor Maureen Cummings, Wakefield Council's cabinet member for environment and communities, said: "I urge anyone with any information on the source of the oil to get in touch as soon as possible and to please keep children and animals away from the water."
Local business owners have been asked to check oil tanks for any leaks.
