Bitumen that spilled into the River Thames weeks ago has washed up on Essex beaches, after 'changing weather conditions'

The company responsable for the spillage, The Port of London Authority, said that due to an accident, tonnes of the material, which is used in construction and to pave roads, was released from a commercial operator, on 17 August.

The MP for Maldon, Sir John Whittingdale, said due to changing weather conditions, external small pieces of debris had been found along the coast from Thurrock to Clacton.

Statement by the Port of London Authority:

“On 17 August, FM Conway, a commercial operator working from Imperial Wharf in Gravesend accidently released bitumen – an oil product used in construction projects and to pave roads – into the River Thames.

"Since then, the Port of London Authority has been using its expertise to coordinate the clean-up operation working with partners across the region.

"So far, we have removed around 15 tonnes of bitumen from the River Thames. We will continue our efforts to search for, contain, and remove the spill.

"If people find what they suspect to be bitumen, please don’t try to remove it yourself but report it to your local council.

"Our expert contractors advise that it is not harmful to human health, but it requires proper handling and disposal to avoid further contamination.

"The Environment Agency will lead the investigation into the cause of this incident.”
