Environmental quality objectives and action targets for water protection Status report and prospects

The water economy and all areas of environmental and resource protection must be concerned with the environmental quality that ought to be achieved in the long term without adversely affecting utilisation by future generations, and with demands for future 'sustainable use' that have to be made today. In Germany water would appear to be a sheer inexhaustible resource. Water serves not only as drinking water for human beings, it is also the essential basis for all life and economic development. Water resources serve a variety of uses, such as the supply of drinking water, cooling water, waste-water discharge, fishery, shipping, energy production, bathing and recreation, activities that often have a lasting negative effect on water quality, ecology and hydromorphological conditions. Despite the fact that drastic and conspicuous effects to surface waters, such as fish kills, is hardly evident today as a result of measures taken over the past thirty years, the results in many areas are still unsatisfactory. In terms of sustainability criteria, water-compatible land use -in farming, for instance, - will not be achieved so long as drinking water abstraction from groundwater is at risk. In order to secure all forms of water utilisation, it is therefore necessary to define the quality that corresponds with the concept of ecologically-intact water bodies to be achieved in the long term.
