Water: nutrient and heavy metal pollution 'decoupling' from growth

These trends are highlighted in a series of new indicators published by the European Environment Agency (EEA), which look at various economic aspects of water pollution and water use in Europe.
'Absolute decoupling' is the implicit aim of many environmental policies, meaning economic growth continues while environmental impacts decrease. 'Relative decoupling' is often used to describe a situation where environmental impacts continue to increase, but at a lower rate than growth.
The data suggests that Europe is generally moving in the right direction in reducing nutrient pollution of water, a major cause of eutrophication. It is still a significant pollution problem, however. Manufacturing industries have also significantly cut their emissions of heavy metals to water between 2004 and 2010, the data shows.
However, at the national level a handful of countries do not show an absolute decoupling trend, either with falling rates of productivity or increasing pollutant emission levels.
