Teams work to curb environmental impact from oil spill in chalk stream

The Wandle flows through south London (Alamy/PA) -

Thousands of litres of oil have spilled into the environment and polluted a rare chalk stream in London, officials have said.

The Environment Agency said an estimated 4,000 litres of oil had spilled into surface water drains and affected the River Wandle, a once-heavily industrialised chalk stream that has been revived and is now home to wildlife such as brown trout to kingfishers.
