River Clean River Clean 3 River Clean 2  This awesome group from Kingston University Sub Aqua Club (KUSAC), including Chris, Tom and Tina from Aquanaut, spent their Sunday cleaning up the River Thames. Collectively they covered about a 50m stretch of the Thames, and hauled out numerous shopping trolleys, bikes, and all sorts. Supported by kayakers and helpers onland to pull out the debris, the team did an amazing job!
