Why a transnational project?
Within Europe the environmental policy is increasingly effected by European regulations and international initiatives. This is useful since pollution does not stop at national borders and therefore aspects of environmental protection have to be solved on an international level. As examples for international initiatives the European Water Framework Directive or international river basin management programmes can be mentioned.
The problem of waste water being polluted with micro pollutants is known, although for many pollutants no solutions - either on a national or on an international level - have yet been found. Especially when different countries are linked by rivers (e.g. in the Rhine catchment), it is necessary to think about common initiatives in order to deal with the problem. This is the reason why transnational cooperation is useful and necessary to be able to develop joint water protection strategies, which are applicable under different national conditions.
