Our oceans and waters are under great pressure. If our lakes and oceans are to flourish and we are to continue having access to clean drinking water in the future, we must protect our waters from hazardous substances and start to see wastewater as a resource.
According to the UN over two billion people lack access to clean water and wastewater treatment services. The prevailing trend, both in Sweden and other parts of the world, is a migration from rural areas to cities. This places great demands on urban water supplies and sustainable wastewater management.
There are many challenges in water research. Nutrients in wastewater contribute to eutrophication. Drug residues that are difficult to separate in treatment plants harm wildlife. All over the world groundwater levels are sinking and climate change will lead to further upsets in water supply systems.
