Contaminant hydrogeology in the German-speaking part of Europe



In the (mainly) German-speaking countries of Europe (the Federal Republic of Germany, the German Democratic Republic, Austria, and Switzerland), 70–85% of the drinking water supplies are drawn from groundwater. Aquifers along many rivers, consisting of glaciofluvial or fluvial granular deposits, are important resources which are recharged by both influent rivers and seepage of winter precipitation. Groundwater is threatened by the continuing and increasing presence of toxic and mobile contaminants from wastedisposal sites, agricultural pesticides and fertilizers, and sewage effluents.
