Reservoirs in Germany

Drinking Water Reservoirs in Thuringia

Poster: Water and Environment

Minimum requirements for the quality of untreated water for the preparation of drinking water

Additional requirements for the quality of untreated water for the preparation of drinking water in view of eutrophication

Natural  and antropogenic factors wich affect water quality

Influence of antropogenic factors


Water Protection, Catchment Aera and Wateshed

Significant sources of water pollution

Waste water problems

Sewage draining away from the conservation areas

Diffuse entries from agriculture 

Relationship between nitrate and agriculture (example)

Reduction of pollution from agriculture
