    Silt Pollution

    We have settlement ponds in place and are trying to stabilise as much ground as possible, but due to the amount of rainfall, it is almost impossible to treat all runoff. It is a very fine particle size, in some cases smaller than 75 microns. We have had a report from Siltbuster in Wales that...
