At a River Wandle cleanup at the start of February, we caught up with Phil Stubbington, a regular South East Rivers Trust volunteer, to find out why he gets involved with our work.
At a stretch of river off Poulter Park in Carshalton, he was one of about 20 people who collected many bulky items and dozens of bags of rubbish.
Items collected ranged from wet wipes and clothing embedded in the berms and silt, to polystyrene, crisp packet, piping, a car number plate and wood that had been furniture.
