Swansea June 29, 2017August 16, 2017 Ben Z Swansea East shore of the Taunton River, with Somerset and Coles river. This is the most heavily trashed area surveyed yet. Not only are there hundreds of tires, there's timbers, trash and styrofoam. These tire rafts are used as wavebreaks. Sadly, they often break loose and find their way ashore. Tidal salt marshes are often the victims of much rubble.
