Beachgoers have been urged not to panic if they spot the sea looking green today. The water at Exmouth Beach is set to turn green or yellow as part of testing by South West Water.
It follows concerns from the local community over reports of sewage being dumped in the water, reports Devon Live. While tests have confirmed that the 'sewage' was actually rotten seaweed and unrelated to South West Water's infrastructure, the company will be carrying out a dye test in a bid to reassure locals.
It's hoped the dye will identify the location of the storm overflow discharge point.
