surface waters

Viele Gewässer enthalten umweltbelastende Stoffe, zu denen auch Arzneimittel und deren Abbauprodukte gehören. Auch im Grundwasser und somit im Rohwasser für unser Trinkwasser werden Rückstände von Arzneimitteln gemessen.
Diese sogenannten Spurenstoffe können sich bereits in sehr niedrigen Konzentrationen nachteilig auf die Lebenswelt im Wasser und die menschliche Gesundheit auswirken.

Surface water quality was considerably improved in recent decades in Germany. Nevertheless, hazardous substances are still emitted into surface waters. Reducing emissions is mandatory. Where do the pollutants originate? Where are emission hotspots? Which measures are efficient? In order to answer these questions, integrated modelling tools have to be applied.

Pesticides can cause damage to the environment. A project coordinated by the German Environment Agency for the European Environment Agency provides the first overview of pesticides in rivers. lakes and groundwater reported by EU Member States. The report confirms that additional measures are necessary to ensure compliance with environmental quality standards in waters.

Nitrogen is an essential nutrient for all living organisms. The use of mineral and organic nitrogen fertilizers to increase yields is therefore common practice in agriculture. Careful and needs-based application is crucial. Excess nitrogen can pollute water and land ecosystems and adversely affect the climate, air quality, and biodiversity.

Our waters are used in a variety of ways, these influence their status. The results of the monitoring of the EC Water Framework Directive show it needs forceful measures in the whole catchment and at the rivers to meet the good status.
