Beaches closed due to an oil spill in Fife will be reopened to the public this weekend.

A massive clean-up operation has been on the go in Limekilns and Charlestown since the oil was discovered on the coastline last month.

The area was closed off to the public and the coastal path route was diverted while the oil was cleaned up and investigations were launched to determine where it came from.

Around 600 tonnes of contaminated seaweed and sand has since been lifted from the three beaches affected and transported to a specialist facility for disposal.

Despite investigations by the Scottish Environment Protection Agency (SEPA), Marine Coastguard Agency (MCA) and Forth Ports, the source of the slick has not been found.

Derek Crowe, senior manager with Fife Council's roads and transportation service, said: "This has been a massive partnership operation with many organisations working together to get this area cleared up and back in public use.

"It's great news that we can reopen the beaches as I know people have been missing the opportunity to use this much loved resource.

"I'd like to thank everyone for their patience while the work was underway . Although residents may still occasionally see a sheen on the water, this will disperse naturally."

The clean-up operation is estimated to cost around £600,000 in total - a cost that will have to be borne by the council if the polluter cannot be identified.

Ian Buchanan, SEPA chief officer, stated: "An extensive investigation carried out by regulatory, chemistry and marine science staff at SEPA has ruled out all identified land-based sources for the pollution found on Limekilns and Charleston beaches.

"SEPA analysed samples of the contamination and compared the results to samples taken from potential sources. No matches were found, and as result SEPA's investigation is closed, unless further information comes to our attention in the future.

"Early suggestions that the oil had come from a land drain appear to have been based on an early visual assessment and no evidence has been found that substantiates this."

The beaches will continue to be monitored as the area returns to its natural habitat.
