Greenpeace has identified many “hot spots” of industrial pollution in Central and Eastern Europe. In Romania, Slovakia and Hungary many ecological time bombs, such as unsecured burning landfills, toxic factory sewage and dead rivers, unsafe cyanide tailing ponds and leaky pipelines, are still ticking. Greenpeace runs the "Clean Water Tour 2002" throughout the region demanding to hold water pollution. Activists will take samples, analyse industrial wastewater and inform the people in more than twenty cities in the three countries about pollution. To be able to work Greenpeace has constructed a technically and ecologically advanced “Action Bus” which will serve as a mobile office and lab during the tour.
