title: [The hygienic situation of the central drinking water supply in the former East Germany--an evaluation of the annual reports on water hygiene from 1984 to 1989].
abstract: In the former GDR an annual report on the situation in the field of communal hygiene had to be elaborated and submitted to the minister of public health. One part of this was the report on the hygienic situation in water supply, worked out by the Reference Laboratory for Water Hygiene in Bad Elster. After the political changes in autumn 1989 it became possible to analyse these reports as a whole. In this paper the reports from 1984 to 1989 are interpreted. The results of the laboratory measurements and field controls by the State Sanitary Inspectorates are shown in 17 graphics and compared to the bacteriological and chemical limits in drinking water standards. Special issue is drawn on the estimation of the number of inhabitants concerned by reduced drinking-water quality or any hazardous situations. The special problems of the different districts are compared in some graphics. The hygienic safety of the central drinking-water supply units is assessed basing on the results of the field controls by the State Sanitary Inspectorate. The Sanitation of the central drinking-water supply facilities in the new federal countries of the FRG is connected with the solution of a variety of technological problems, particularly the improvement of the water treatment techniques and the restoration of the pipe systems. The use of surface waters from extremely polluted rivers generates a high hygienic risk and requires the sanitation of the rivers. The high number of existing protection zones in the catchment areas for drinking-water is a valuable precondition to ensure the hygienic safety of the drinking-water supply in the new federal countries.
