Fly-tippers are blighting a Dearne beauty spot and killing off wildlife by dumping industrial waste there.
In recent weeks people have illegally dumped litres of oil and more than 20 tyres into a pond at Horsefair Park, Swinton.
Littler bugs have also dumped household items in the nearby woodland, such as large wooden and uPVC doors.
Environmentalists hit out this week and said the dumped litter is killing off wildlife habitats and blighting an area popular with dog walkers.
Meanwhile, Rotherham Council bosses said it is costing the cash-strapped authority over £100, 000 a year to clear up the mess and urged people to take their litter to recycling centres.
Swinton councillor Ken Wyatt, cabinet member for health and wellbeing, said: “The oil and tyres issue will have cost the council several thousands of pounds to remove.
“But not only that there were coots, ducks, fish and insect life in there, much of which has now gone.
“We used to have school visits here to look at the wildlife, but the pond and park are being blighted by vandalism.
“It is killing off wildlife and ruining a park for dog walkers and visitors.”
He added: “I would urge people to use proper waste recycling centres. The nearest one to Swinton is in Warren Vale, Rawmarsh.”
David Burton, director of the council’s Streetpride team, said the authority deals with about 45 incidents of fly-tipping every week, which has cost the council more than £117,000 in the last financial year.
He added: “While fly-tipping is a blight on the environment wherever it occurs, it is particularly galling when it happens in areas such as parks, because everyone’s enjoyment is spoilt by a few thoughtless individuals, who affect the quality of life for local residents.
“It is they who have to live with the consequences of the actions of a small minority of individuals who refuse to use the facilities that the council makes available such as the four household waste recycling centres and the bulky waste collection service.
Mr Burton added there has been an increase in fly-tipping incidents this last year because people are using hi-tech mapping devices to target places to dump their waste.
He said: “Unfortunately, there are certain places around the borough where we do experience more incidents of fly tipping as well as hot-spots that have to be tackled individually.
“These are tackled by increased numbers of scheduled visits, the use of enforcement and CCTV cameras.
“Where we have evidence to do so, the council will issue fixed penalties of £80 and, if a case is serious enough, we will and do take the offenders to court where they can face up to five years in imprisonment and a fine of up to £50,000.”
